How to Use the Commission Calculator
- Choose a flat rate or tiered rates.
- Enter the sales amount for the period.
- Enter the commission rate, or set tiers if you chose tiered.
- Add base pay, your share of the commission and an optional goal.
- Read your commission, total pay, effective rate and sales needed.
Choose Flat rate if you earn the same percentage on every dollar sold, then enter the sales amount and the rate. Choose Tiered rates if your plan pays more as sales grow. Set the upper limit and rate for the first two tiers and the rate for everything above them. Then pick the tier type: graduated plans pay each band of sales at its own rate, while whole-amount plans pay the entire sales total at the rate of the highest tier reached.
Add any base pay for the same period and your share of the commission if it is split with a brokerage, team or partner. Enter a commission goal to see the sales you need to reach it. The breakdown lists how each band contributes, so you can check the result against your pay statement.
Commission Formulas
graduated: commission = Σ (sales in each band × that band's rate)
whole amount: commission = sales × rate of the tier reached
your commission = commission × your share
effective rate = commission before split ÷ sales
The two tier types can give very different pay on the same sales. Graduated tiers rise smoothly, while whole-amount tiers jump at each threshold, which creates a strong push to cross the next level. The sales needed for a goal are found by searching for the smallest sales figure that produces the goal.
Commission plans often pay monthly or quarterly. Enter the sales for the same period as the base pay so the total matches your pay statement, or use yearly sales and a yearly salary for an annual view. A split is applied after the commission is calculated, so tier thresholds use total sales, not your share.
The effective rate helps when comparing a job offer with a lower base and richer commission against one with a higher base. Multiply your expected sales by each plan's effective rate and add the base pay to compare total earnings.
Worked Examples
At a flat 5%, $50,000 of sales earns $2,500 of commission. With $2,000 of base pay the total is $4,500. To earn a $3,000 commission at 5%, sales must reach $60,000. With a 70% split, the same sales would pay you $1,750.
With tiers of 3% up to $10,000, 5% up to $25,000 and 7% above that, graduated commission on $50,000 is $10,000 × 3% + $15,000 × 5% + $25,000 × 7% = $300 + $750 + $1,750 = $2,800, an effective rate of 5.60%. On a whole-amount plan, all $50,000 is paid at 7%, or $3,500. At $20,000 of sales the graduated plan pays $800.
Commission on Common Sales Amounts
| Sales | 3% | 5% | 7% | 10% |
|---|---|---|---|---|
| $10,000 | $300 | $500 | $700 | $1,000 |
| $25,000 | $750 | $1,250 | $1,750 | $2,500 |
| $50,000 | $1,500 | $2,500 | $3,500 | $5,000 |
| $100,000 | $3,000 | $5,000 | $7,000 | $10,000 |
| $250,000 | $7,500 | $12,500 | $17,500 | $25,000 |
Commission is normally taxable employment or self-employment income. The calculator shows gross figures before any tax or payroll deductions.
Tips for Commission Plans
- Read your plan for what counts as a sale: invoiced, paid, or net of returns and discounts. That changes the sales figure you should enter.
- Check whether the plan uses a draw against commission, where advances are deducted from future commission.
- Compare plans by effective rate at the sales level you expect, not only by the top tier rate.
- For real estate commissions on a home sale, use our realtor commission calculator, which handles agent splits and sales tax on fees.
- Keep your own record of sales and expected commission to reconcile each pay period.
Assumptions and Limits
The calculator supports a flat rate or three tiers. Plans with caps, accelerators by quarter, clawbacks, quotas or team pools need extra steps beyond this tool. Amounts work in any currency and no tax is deducted. For payroll questions, check your written plan and ask your employer.
Frequently asked questions
How do I calculate commission?
Multiply the sales amount by the commission rate as a decimal. Sales of $50,000 at a 5% commission rate earn $2,500, before any split or tax.
How does tiered commission work?
Tiered plans pay higher rates as sales grow. In a graduated plan, each band of sales is paid at its own rate. In a whole-amount plan, all sales are paid at the rate of the highest tier reached.
How do I calculate my commission rate?
Divide the commission earned by the sales amount and multiply by 100. Earning $2,800 on $50,000 of sales is an effective commission rate of 5.6%.
How much do I need to sell to earn a certain commission?
With a flat rate, divide the commission goal by the rate. A $3,000 goal at 5% needs $60,000 of sales. For tiers, the calculator finds the figure for you.
What is a commission split?
A split shares the commission between you and a brokerage, team or partner. On a 70/30 split you keep 70%, so $2,500 of commission pays you $1,750.
Is commission taxed differently from salary?
Commission is generally taxed as regular employment income, though employers may withhold tax on it differently from salary. Self-employed agents usually pay their own tax on commission income.
