Enter your sales for the pay period and the commission plan in your contract: one rate, or up to three rates split by two thresholds. You get the commission before tax, total pay with your basic pay and, if you want, a check against the minimum wage in force across the UK (£12.71 an hour for workers aged 21 and over since 1 April 2026) for the hours you work.
Choose how commission is worked out
Flat rate: one rate on all sales. Banded: each slice of sales earns the rate of its band, as with tax bands, so only the sales above a threshold earn the higher rate. Retroactive: once sales reach a threshold, that tier’s rate applies to all your sales from the first pound. A threshold is reached when sales are equal to it or above it.
Enter the rates and thresholds
The first rate applies below the first threshold; enter 0 if nothing is paid until you hit a target. The second threshold is optional: leave it empty for a two-rate plan. Enter the figure your plan pays on, whether that is sales invoiced, cash received or margin, with or without VAT.
Check against the minimum wage
Tick ‘Check against the minimum wage’, choose a monthly or weekly pay period and enter your hours a week. For a month, the calculator counts weekly hours × 52 ÷ 12. The hourly rates are £12.71 at 21 and over, £10.85 at 18 to 20, and £8.00 under 18 or for apprentices, the same in England, Scotland, Wales and Northern Ireland. The minimum wage covers workers, not the genuinely self-employed. If your contract guarantees more, choose ‘Other hourly minimum’.
Rounding and reuse
Amounts are rounded to the nearest penny, with halves rounded up; with bands, each band is rounded and the bands are then added. Copy the workings in one click, export them as a CSV file or save the result to Priostack.
Flat rate: commission = sales × rate.
Banded: commission = the sum, band by band, of (sales within the band × the band’s rate).
Retroactive: commission = sales × the rate of the highest tier reached.
Minimum for a month = hourly rate × hours a week × 52 ÷ 12; top-up due = minimum − (basic pay + commission), when positive.
Example: £45,000 of sales under a three-rate plan
A salesperson on £1,200 a month basic pay earns 2% up to £20,000 of sales, 4% from £20,000 to £40,000 and 6% above that. With £45,000 of sales in the month, the banded plan pays £400.00 + £800.00 + £300.00 = £1,500.00, so total pay is £2,700.00. As a retroactive plan, 6% applies to all sales: £2,700.00. In a quiet month with £10,000 of sales, banded commission is £200.00 and total pay £1,400.00, below the £2,065.38 minimum for 37.5 hours a week at £12.71, so the employer must pay an extra £665.38.
