Open calculator →Choose the calculation that matches the decision
- Use Overtime Pay when you need the gross amount created by a contractual multiplier.
- Use Overtime Break-Even when accepting the shift creates travel, childcare, food or other incremental costs.
- Use Shift Premium & Allowance when the enhancement is a percentage, fixed amount or recurring allowance.
- Use Holiday Hours Value to compare leave packages that use different working-day lengths.
Worked comparison: total overtime pay is not the same as the premium
For an illustrative base rate of £15 per hour, six overtime hours paid at 1.5× produce £135 gross. The same six hours at the ordinary rate would be £90, so the enhancement created by the multiplier is £45.
| Step | Calculation | Illustrative result |
|---|---|---|
| Total gross overtime pay | £15 × 1.5 × 6 hours | £135 |
| Ordinary-rate portion | £15 × 6 hours | £90 |
| Premium above ordinary pay | £135 − £90 | £45 |
| After £12 travel and £28 childcare | £135 − £12 − £28 | £95 before personal deductions |
The first calculator answers “what is the gross overtime worth?” The break-even calculator answers the different question “what remains after costs created by accepting the shift?” Neither figure is take-home pay, and neither decides whether the arrangement complies with a contract or employment law.
Use the rate in your own contract
There is no universal UK overtime multiplier. Enter the rate, hours and frequency that actually apply, and keep uncertain overtime availability separate from guaranteed salary. Annual projections are only as reliable as the frequency assumption supplied.
