Sales Commission Calculator: What Do I Earn On This Deal?

Standard SaaS commission rates center around 10% of the revenue base a plan pays on — but the real number on your deal depends on your rate structure, deal composition, and plan conditions, so the calculator above recalculates it the moment you change an input.

You close the deal. The Slack messages come in — "Nice one," "Huge win." You open your CRM, look at the contract value, and do the math in your head: "Alright, that's about twelve grand." Then a few weeks later, the commission hits your account. And it's not twelve grand. It's lower. Or delayed. Or split in a way you didn't expect.

What Is Sales Commission

Sales commission is the variable portion of compensation paid as a percentage of the revenue a rep generates, calculated against a revenue base (ACV or TCV), a rate structure (flat, tiered, or cliff), and any plan conditions such as thresholds, caps, or accelerators. It differs from total on-target earnings, which also includes base salary and bonuses.

Why One Deal Doesn't Equal One Simple Commission Number

Most deals are not a single clean number at a single rate. They are a mix of products, services, and categories that can each be paid differently depending on your plan. Treating everything as one number usually leads to an overestimate of what you will actually earn.

Enterprise and mid-market deals are often composed of multiple elements: software licenses, professional services, hardware, training, and support. Each of these components may be tied to a different commission rate. If your plan pays 9% on software and 4% on services, a $214,000 deal that includes $151,000 of software and $63,000 of services does not produce a single blended-rate figure. It produces $13,590 on the software portion and $2,520 on the services portion, for a total of $16,110.

The gap between a simplified calculation and the real one can be significant, especially on larger deals. This is where the calculator becomes particularly useful — by entering each component separately with its corresponding rate, or by modeling your plan's actual structure, you get a much more accurate view of what the deal is really worth to you.

How a Discount Affects Your Commission

When you offer a discount to close a deal, it doesn't just lower the price for the customer — it directly changes the math behind your paycheck. How much it costs you depends entirely on which of three structures your plan uses, and the exact dollar impact on your specific deal is what the discount module in the calculator above computes the moment you enter your numbers.

Gross commission — discount absorbed by the company

In a gross commission plan, your commission is calculated on the original contract value before any discount is applied. You offer 15% off a $100,000 deal — your commission is still calculated on $100,000. The company absorbs the cost of the discount entirely.

This structure is rare in B2B sales. It exists in some early-stage startups where the priority is closing logos at any cost, and in channel or partner deals where discount authority is managed separately from rep compensation. If you are not sure which structure your plan uses, check the "revenue base" language in your comp plan document — if it says "list price" or "pre-discount value," you are on a gross plan.

Net commission — the B2B standard

Net commission is the default in B2B sales. Your commission applies only to the final contract value after discount. A 15% discount on a $100,000 deal means your commission base is $85,000. At a 10% rate, that is $8,500 instead of $10,000 — a $1,500 reduction in your paycheck from a single discount decision.

The relationship is linear and direct: every percentage point of discount you give costs you the same percentage of your commission on that deal. A 10% discount costs you 10% of your commission. A 20% discount costs you 20%. There is no cushion, no recovery mechanism — the discount comes straight out of your variable pay. Enter your deal amount, commission rate, and discount percentage in the calculator above to see your exact number.

Penalized rate — the double hit

Some plans go further than simple net commission. When a rep exceeds a defined discount threshold — typically 15% to 20% — the commission rate itself drops in addition to the reduced base. The rep loses twice: once because the revenue base is lower, and once because the rate applied to that lower base is also reduced.

Example: your standard rate is 10%, your plan penalizes discounts above 20% by dropping the rate to 5%. You offer 25% off a $100,000 deal.

• Net price: $75,000
• Penalized rate: 5%
• Commission: $3,750

Without the discount, the same deal at list price would have paid $10,000. The 25% discount cost you $6,250 — more than the discount itself was worth to the customer in dollar terms. This is the math most reps do not run before offering the discount. The penalized rate toggle in the calculator's discount settings lets you model this exact scenario for your plan's specific threshold and reduced rate — the result depends entirely on your numbers, not a generic estimate.

The Three Discount Structures and What Each Costs You

Every B2B commission plan handles discounts one of three ways. Which one applies to you determines how much of your commission each percentage point of discount actually costs — and the difference between structures on the same deal can be thousands of dollars.

Structure 1: Gross (pre-discount base)

Commission is calculated on the original price regardless of discount. The rep's paycheck is unaffected by the discount decision.

When you see it: Early-stage startups prioritizing logo acquisition, channel deals, plans where discount authority is managed separately.

What it costs you: Nothing. The company absorbs the discount.

Structure 2: Net (post-discount base) — most common

Commission is calculated on the final price after discount. Every point of discount reduces your commission by the same percentage.

When you see it: The default in B2B sales across SMB, Mid-Market, and Enterprise.

What it costs you on a $100K deal at 10% rate:

The exact loss on your deal depends on your deal size and commission rate — toggle the discount module in the calculator above to see your specific numbers.

Structure 3: Penalized rate (double hit)

Commission is calculated on the net price AND the rate drops once the discount exceeds a threshold. Two reductions, one discount decision.

When you see it: Plans designed to protect margin, typically Mid-Market and Enterprise plans where large discounts materially damage CAC payback periods.

What it costs you on the same $100K deal at 10% rate, with a 20% threshold and 5% penalized rate:

The jump between 20% and 25% discount is not linear — it is the point where the penalty kicks in and the commission drops by more than double what the additional 5% discount would cost under a net-only structure. This is the scenario the calculator's penalized rate setting is built to model, because no mental math produces this number reliably. Enter your threshold and penalized rate in the discount drawer to see exactly what your plan costs you at any discount level.

What a Discount Actually Costs You at End of Quarter

The math above shows the cost of a single discount on a single deal. The real question most reps face at end of quarter is different: is the commission loss from discounting worth it to close the deal before the period ends, compared to losing the deal and closing nothing?

The answer depends on two numbers your plan determines: how much commission you lose per point of discount, and whether closing this deal at a discount changes your attainment enough to trigger an accelerator or cross a bonus threshold.

If you are at 95% of quota and a discounted deal at 25% off pushes you to 102%, the commission loss from the discount may be offset by the accelerator that kicks in above 100%. If you are at 75% of quota and the deal only gets you to 85%, no threshold changes — you are simply taking a lower commission on a discounted deal with no compensating upside.

This is why the discount calculation cannot be done in isolation from your quota position. The exact tradeoff on your deal, at your current attainment, with your specific discount structure, is what the calculator computes when you combine the deal amount, your discount, and your current quota attainment — the result depends on all three variables simultaneously, which is why no generic answer applies to your situation.

How to Know Which Discount Structure Your Plan Uses

Most reps do not know which discount structure their plan uses until they receive a commission statement that is lower than expected. The three questions to ask when you read your comp plan document:

Question 1: What is the commission base? Look for language like "net revenue," "invoiced amount," "list price," or "pre-discount value." Net revenue and invoiced amount indicate a net structure. List price or pre-discount value indicate a gross structure.

Question 2: Is there a discount threshold? Search for "discount authority," "discount approval," or "commission rate adjustment." If any of these appear alongside a percentage, you are likely on a penalized rate structure.

Question 3: What happens above the threshold? If a threshold exists, the plan should specify whether the reduced rate applies to the full deal or only to the portion above the threshold. The calculator models the most common version: the penalized rate applies to the entire net price once the threshold is crossed.

If your plan document does not answer these questions clearly, ask your manager or RevOps before you offer a discount — not after. The difference between a 15% and 25% discount on a $150,000 deal under a penalized rate structure can exceed $10,000 in commission, and the exact amount for your deal and your plan is what the discount module above calculates in real time.

Formula

Commission (flat)              = Effective Revenue × Flat Rate

Commission (tiered, prospective) = Σ over tiers of:
                                    min(Revenue, TierEnd) − TierStart) × TierRate

Commission (tiered, retroactive) = Revenue × Rate of highest tier reached

Effective Revenue = Revenue,
  or Revenue − (FloorThreshold% × Quota) if a floor applies only above threshold

Final Commission = min(Commission, Cap)   [if a commission cap is enabled]

Total Compensation = Fixed Salary + Commission + Bonuses + SPIFFs + MBOs
                      − Clawback + True-Up Delta + Draw Advance

Effective Revenue is the deal or period revenue commission is actually calculated on, after any floor (minimum attainment threshold) is applied. Attainment is revenue divided by quota, expressed as a percentage. Tier structure determines whether each slice of revenue is paid at its own tier's rate (prospective/marginal) or whether crossing a tier retroactively raises the rate on all revenue (cliff). Cap is an optional ceiling on total commission, expressed as a fixed amount or a percentage of variable target. Decelerator, when enabled, overrides the standard rate structure below a set attainment threshold, paying a reduced rate instead.

How Sales Commission Actually Works

At its core, commission is straightforward: you generate revenue for the company, and you receive a percentage of that revenue as variable compensation. In technology and SaaS sales, that percentage typically centers around 10%, but can range from 5% to 15% depending on your role, the complexity of the deal, and the company's compensation structure.

What matters is not just the rate itself, but how it is applied. The same "10% commission" can produce very different outcomes depending on what revenue it applies to, when it applies, and under what conditions it is triggered. Two sales reps working at the same company, with the same headline commission rate, can end up with meaningfully different earnings on identical deals simply because of differences in plan structure.

What Your Commission Actually Applies To (ACV vs TCV vs Revenue Streams)

Your commission rate only becomes meaningful once you understand the base it is applied to. Most SaaS companies pay commission on Annual Contract Value (ACV), which represents the value of the first year of a contract. Others pay on Total Contract Value (TCV), which includes the full duration of the agreement.

A three-year contract worth $127,500 per year will generate $12,750 in commission under an ACV model at a 10% rate, but $38,250 under a TCV model. The difference is substantial, and it is one of the first things to clarify when evaluating a plan — the exact gap on your own contract depends on its length and your plan's rate, which is exactly what the calculator's revenue-base toggle lets you check.

In addition to contract structure, most compensation plans divide revenue into multiple streams. New business, upsell or expansion, and renewals are typically treated differently, each with its own commission rate. New business tends to carry the highest rate, as acquiring new customers is more demanding. Expansion revenue usually comes with a lower rate, and renewals often sit at the bottom of the range or are not commissioned at all. This means that a single deal can involve multiple commission calculations, depending on how it is structured.

Where Your Commission Rate Comes From

Your commission rate is not arbitrary. It is derived from the relationship between your On-Target Earnings (OTE) and your quota. In many SaaS organizations, compensation follows a 50/50 split between base salary and variable earnings, with a quota set at approximately five times OTE. These two variables together determine the effective commission rate.

For example, a rep with $135,000 OTE might have a $67,500 base salary and $67,500 in variable compensation. If their quota is $675,000, the resulting commission rate is 10%. Understanding this relationship gives you leverage in negotiation. If you reduce the quota while keeping the same variable compensation, the effective commission rate increases, even if the OTE remains unchanged. A $67,500 variable component against a $562,500 quota produces a 12% rate instead of 10%, making every deal more valuable — the exact rate on your own plan depends on your specific OTE, split, and quota, which is exactly what the calculator computes.

Sales Commission Rates by Role (Benchmarks)

Commission structures vary depending on the role. Account Executives typically operate with a base salary representing 50 to 60% of OTE and commission rates ranging from 8% to 15% on ACV, depending on the segment and deal complexity.

Account Managers tend to have a higher base component, usually between 60 and 70%, with commission rates between 5% and 10% on renewal and expansion revenue. SDRs and BDRs are generally compensated through fixed bonuses tied to meetings or qualified opportunities rather than revenue percentages. Customer Success Managers are even more heavily weighted toward base salary, with variable compensation linked to retention or customer satisfaction metrics.

Understanding these benchmarks helps you assess whether your plan is competitive and identify where there may be room for negotiation.

When You Actually Get Paid (And Why It's Delayed)

Closing a deal and receiving your commission are two separate events. In most SaaS companies, commission is paid at the time of deal closure — once the contract is signed, the payout is included in the next payroll cycle. Some organizations operate on a quarterly payout model, where commissions are calculated and distributed at the end of each quarter, introducing a delay but providing predictability. Others pay commission on collection, meaning you are only paid once the client has paid their invoice — depending on payment terms, this can delay your commission by several months.

These differences have a direct impact on your cash flow, even if the total commission amount remains the same. The calculator's payment timing settings let you model these scenarios and understand when you can realistically expect to receive your earnings.

What a Good Commission Plan Looks Like

A competitive commission plan is defined by a combination of structure and balance. In most SaaS environments, a strong plan offers a commission rate between 8% and 12% at full quota attainment, along with a meaningful accelerator above quota that increases the rate by at least 1.5 times. The quota-to-OTE ratio typically falls between 4:1 and 6:1, which reflects a balance between achievable targets and meaningful upside. Uncapped commissions are also a key characteristic of competitive plans, ensuring that top performers continue to be rewarded as they exceed their targets.

If your plan deviates significantly from these benchmarks, it is worth modeling the difference. The gap between your current structure and a market-standard plan can often be quantified clearly and used as a basis for negotiation. If you want to go further and model your entire compensation plan rather than a single deal, the OTE calculator lets you simulate your real earnings dynamically at any attainment level — base salary, commission streams, accelerators, and bonuses all included.

Methodology

The calculator treats compensation as a set of independent, toggleable rule blocks — fixed salary, commission (flat, margin, tiered-prospective, or tiered-retroactive), decelerator, sales-type rates, territory splits, commission cap, objective bonuses, new-logo bonuses, contract-duration multipliers, SPIFFs, MBOs, ramp, draw, clawback, and annual true-up — rather than a single blended formula. This mirrors how real B2B compensation plans are actually built: each rule is negotiated and administered somewhat independently, and stacking them in one blended number would hide which lever changes the outcome.

Commission on a specific deal is computed as the marginal difference between the commission calculated on revenue before the deal and revenue after the deal, which correctly accounts for tier boundaries — a deal that pushes a rep from 95% to 105% of quota earns commission at more than one rate. The quota-to-OTE ratio assessment (generous below 3:1, market standard between 3:1 and 5:1, aggressive above 5:1) is a plan-design heuristic, not a prediction of any individual rep's outcome.

The model does not attempt to predict whether a rep will close a given deal. It quantifies what a defined plan structure pays out for a given revenue outcome.

Assumptions

• Commission on a tiered-prospective plan is marginal: each tier rate applies only to the slice of revenue within that tier's band.
• Commission on a tiered-retroactive (cliff) plan applies the highest tier rate reached to the entire revenue amount, not just the portion above the threshold.
• A commission floor, when enabled, either zeroes out commission entirely below the threshold or restricts the commissionable base to revenue above the threshold, depending on configuration.
• A decelerator, when enabled, overrides the standard commission structure entirely rather than combining with it.
• New-logo bonuses, SPIFFs, and MBOs are additive to commission and are not affected by tier boundaries or caps unless explicitly capped.
• The quota-to-OTE ratio and its "generous / market / aggressive" labels are derived purely from the ratio of quota to OTE, independent of industry, region, or deal size.
• A draw, when enabled, guarantees a minimum monthly payout only for its configured duration; commission earned above the guarantee is paid in full once the draw period ends.

Limitations

The calculator computes what a defined compensation plan pays for a given revenue or deal outcome — it does not predict whether that revenue will actually be generated, nor does it model probability of closing a deal, deal slippage, or forecast accuracy. It does not account for territory-specific market conditions, personal quota adjustments outside the modeled ramp schedule, or plan changes mid-period. Benchmarks for "typical" rates, base-to-variable splits, and quota-to-OTE ratios reflect common B2B SaaS plan conventions and may not match every company, industry, or region. Tax treatment, currency conversion effects, and company-specific payroll timing beyond the modeled payment trigger are not included.

What This Means for Your Next Deal

Understanding the real structure behind your commission changes two things. First, it removes the guesswork between closing a deal and knowing what it's actually worth — instead of a rough mental estimate, you get a number that reflects your plan's actual rate structure, tiers, and conditions. Second, it gives you a concrete basis for negotiation: because the commission rate is mathematically derived from OTE and quota, you can see exactly how a quota change, a tier adjustment, or an added floor would move your take-home pay before you agree to a new plan.

The calculator above lets you model your specific deal or plan structure directly. This page explains why the number it produces is almost never the one you did in your head — and now you know exactly why.
