What Is a Commission Calculator?
A commission calculator helps you calculate your commission earnings based on sales, commission rate and structure. This commission calculator UK shows your commission, total pay and estimated take-home pay after tax and National Insurance.
How to Use the Commission Calculator
Select your commission type (percentage, flat rate or tiered), enter your sales amount, commission rate or flat rate, and optionally add your base salary. Click Calculate Commission to see your earnings.
How Commission Is Calculated
Total Pay = Base Salary + Commission
Commission Example
Example: Sales amount £10,000, commission rate 5%, base salary £2,000
- Commission: £10,000 × 5% = £500
- Total pay: £2,000 + £500 = £2,500
Commission Types
- Percentage of Sales: Earn a percentage of your sales value
- Flat Rate: Earn a fixed amount per sale
- Tiered: Earn different rates based on sales thresholds
Tiered Commission Example
Example: 5% up to £10,000, 10% over £10,000, sales amount £15,000
- First £10,000: £10,000 × 5% = £500
- Next £5,000: £5,000 × 10% = £500
- Total commission: £1,000
How Commission Affects Tax and NI
Commission is subject to Income Tax and National Insurance just like regular pay. This calculator estimates the tax and NI on your total earnings.
Commission vs Base Salary
Your base salary is your guaranteed regular pay. Commission is variable pay based on performance. Together they make up your total earnings.
Common Commission Mistakes
- Forgetting tax and NI — commission is subject to deductions.
- Using the wrong rate — check your commission structure.
- Not including base salary — total pay includes both.
- Not accounting for tiers — tiered structures have different rates.
Important: This calculator provides estimates only. Actual commission and tax may differ based on your employment contract and tax code. Always check your payslip for exact figures.
