Flat-rate gross compensation before taxes, draws, or clawbacks. Base pay is not split.

Commission split

  • Your commission500.00 USD
  • Other share of commission0.00 USD

These amounts add to the commission pool. Base pay is excluded from the split.

Commission splits and gross compensation

The commission pool is the amount before splitting. Your commission is the share you retain. Gross compensation adds base pay, while the effective rate expresses your retained commission as a percentage of eligible sales.

To compare period compensation on an hourly basis, use the Salary to Hourly Calculator .

The formula

Commission pool = sales × rate/100. Your commission = pool × share/100. Gross pay = base pay + your commission. Effective rate = rate × share/100.

The calculator uses a single flat percentage applied to entered eligible revenue, then a separate share percentage. It does not decide whether a contract calculates commission on revenue, profit, collected invoices, or another base; enter the base required by your agreement.

Worked example

Eligible sales of 10,000 at a 5% rate produce a commission pool of 500. Keeping 100% and adding base pay of 1,000 gives gross compensation of 1,500. Keeping 60% instead produces commission 300 and gross pay 1,300.

How to use this calculator

  1. Enter eligible sales for one compensation period.
  2. Set the flat commission rate and your retained share; leave share at 100% when there is no split.
  3. Add base compensation for that same period and calculate the gross amounts.

Choose the commission base before calculating

A rate alone does not define compensation. Some arrangements use gross sales; others exclude refunds, discounts, taxes, shipping, or uncollected invoices. If commission is based on profit, first determine the eligible profit and enter that amount as the base. The tool cannot infer contract terms from a sale price.

A split differs from a lower sales rate

A split divides an already calculated pool among representatives or parties. For a 5% pool and 60% share, your effective rate is 3% of eligible sales. The remaining 40% is shown separately. The base-pay input is added after splitting and is not itself shared by this calculation.

Keep time periods consistent

Monthly eligible sales should be paired with monthly base pay, rather than an annual salary. Gross pay here precedes taxes, withholding, benefits, draws, clawbacks, and other adjustments. A tiered plan can use different rates at different thresholds, which a single flat rate does not reproduce. Review the agreement before using the result for payroll.

Assumptions & limitations

What this calculation assumes

  • One flat commission rate applies to all entered eligible sales.

What to keep in mind

  • No marginal tiers, accelerators, caps, taxes, recoverable draws, or refund clawbacks.

Common questions

Can I use this for an agent or broker split?

Yes, for a flat commission pool and one retained share. Enter the eligible transaction amount and agreed percentages.

Is gross pay the same as take-home pay?

No. The result combines base compensation and commission before deductions or taxes.
