Commission Calculator, flat & tiered.

Calculate sales commission for any deal — use a single flat rate or build a tiered bracket structure with up to eight levels. Add a deal multiplier to project weekly, monthly, or annual earnings. Results include effective rate, net proceeds, and a full tier-by-tier breakdown.

Sales commission guide

Understanding sales commission structures.

A sales commission is a performance-based payment calculated as a percentage of the revenue a salesperson generates. It aligns individual incentives with company goals, the more you sell, the more you earn. Commission structures vary significantly across industries, roles, and companies, from a simple flat percentage to multi-tier accelerator schedules that reward high-volume producers.

Flat-rate commission: simple and predictable

A flat commission applies the same percentage to every dollar of the sale, regardless of size:

Commission = Sale Amount × (Rate / 100)

For example, a real estate agent earning 3% on a $450,000 home receives:

Commission = $450,000 × 0.03 = $13,500

Flat commissions are easy to understand and communicate, making them common in real estate, auto sales, insurance, and retail. The downside is that they don't accelerate motivation for higher-value deals — a $1M deal earns the same rate as a $50K deal.

Tiered (accelerated) commission: brackets that reward performance

A tiered commission structure applies different rates to different portions of a sale, similar to progressive income tax brackets. Higher tranches earn a higher percentage, incentivising salespeople to close larger deals or exceed quota:

Tier commission = Applicable amount in bracket × Tier rate Total = Σ (commission from each tier)

Consider a $120,000 deal under the Sales accelerator preset (5% / 7% / 10%):

TierRangeRateIn this tierCommission
1$0–$25,0005%$25,000$1,250
2$25K–$100K7%$75,000$5,250
3$100K+10%$20,000$2,000
Total$120,000$8,500

The effective rate is $8,500 ÷ $120,000 ≈ 7.08%: lower than the top tier rate because only the deal's highest tranche earns 10%. This blended rate is what the commission calculator displays.

Flat vs. tiered, which is better?

For employers / companies, tiered structures are more cost-efficient at scale: the bulk of deals (smaller ones) earn a lower rate, and only the exceptional deals unlock the top tier, where the marginal cost of the commission is offset by the higher deal value.

For salespeople, tiered structures with accelerators above quota can be extremely lucrative. A rep who closes 2× quota at a 10% top-tier rate dramatically outearns one on a flat 6% rate. Understanding which tier a prospect's deal will fall into helps salespeople prioritise their pipeline.

What is the effective commission rate?

The effective rate is your total commission divided by the total sale amount — a single percentage that summarises what you actually earned, regardless of how many tiers contributed. For flat commissions, effective rate equals the stated rate. For tiered commissions, it lies between the lowest and highest tier rates:

Effective rate = (Total commission / Sale amount) × 100

The effective rate is the most useful number for comparing two commission structures against each other, or for forecasting earnings across a portfolio of deals of different sizes.

Projecting earnings, using the deal multiplier

Use the Number of sales field to project earnings across a period. Set it to your expected monthly deal count and the calculator shows your total commission. Common benchmarks:

  • Weekly: 1–5 deals for an individual rep
  • Monthly: 5–20 deals depending on ACV
  • Annual: 60–240 deals (50–200 per month ×12 for high-volume roles)

Note that real earnings are more complex; variable deal sizes mean average commission per deal may be higher or lower than any single example. For the most accurate forecast, use the calculator with your median deal size and your actual close rate applied to a full pipeline.

How to negotiate your commission structure

  1. Know your effective rate target. Use this calculator to model your expected deal mix before negotiating. If your average deal is $80K, a 7% flat rate beats a 5%/10% two-tier if your top-tier deals are rare.
  2. Request accelerators, not just higher base rates.A 5% base with 10% above quota often delivers more total earnings than a flat 7% if you consistently exceed quota.
  3. Watch the clawback and draw provisions.Many commission plans include clawbacks (repayment if a deal cancels) and a recoverable draw (advance commissions that must be paid back if you leave). These can significantly affect net take-home.
  4. Ask for the OTE breakdown. On-Target Earnings (OTE) is only meaningful if you know the quota, the base salary portion, and whether 100% quota attainment is realistic given territory and product.
