How the Overtime Pay Calculator Works

The WeFixPay Overtime Pay Calculator UK helps you estimate how much extra you could earn when working overtime. Enter your normal hourly rate, the number of normal hours in your pay period and the overtime hours you expect to work. You can then choose an overtime multiplier such as standard rate, 1.25x, time and a half (1.5x), double time (2x), or enter a custom rate. The calculator shows your normal pay, overtime hourly rate, overtime earnings and estimated total gross pay before deductions.

Common Overtime Pay Rates in the UK

Overtime pay rates are usually set by your employer or employment contract. There is no single overtime multiplier that applies to every UK worker. Some employers pay overtime at the normal hourly rate, while others use enhanced rates such as time and a quarter, time and a half or double time. Your rate may also vary depending on whether you work evenings, nights, weekends or bank holidays.

For official guidance on overtime pay and workers’ rights, see the GOV.UK overtime rights guidance.

Overtime Pay Calculator UK Example

Here is a simple example of how overtime pay can be calculated. Suppose your normal hourly rate is £14.50 and you normally work 37.5 hours in the pay period. Your normal pay would be £543.75.

If you then work 10 hours of overtime at time and a half (1.5x), your overtime hourly rate would be £21.75. Ten overtime hours would therefore produce £217.50 in overtime pay.

Your estimated total gross pay for the period would be £761.25 before Income Tax, National Insurance, pension contributions and any other deductions.

You can use the calculator above to change the hourly rate, overtime hours or multiplier and instantly compare different overtime scenarios.

Overtime pay = hourly rate × overtime multiplier × overtime hours

Does Overtime Pay Affect Tax and National Insurance?

Overtime earnings are normally included as part of your gross pay. This means working additional hours can increase the amount of Income Tax and National Insurance deducted from your pay, depending on your total earnings and personal circumstances.

The gross overtime figure calculated above is therefore not necessarily the amount of extra money that will reach your bank account. Your final take-home pay may also be affected by pension contributions, student loan repayments and other workplace deductions.

If you want to estimate the effect of overtime on your deductions, you can also use the WeFixPay UK Tax Calculator and National Insurance Calculator. Once you receive your payslip, the WeFixPay Payslip Checker can help you review the overtime and deductions that were actually recorded.

Things to Check Before Working Overtime

Overtime Pay Calculator UK FAQs

Is overtime always paid at a higher rate?

No. Your overtime rate depends on your employment contract or employer’s overtime policy. Some employers pay overtime at the normal hourly rate, while others offer enhanced rates such as 1.5x or 2x.

How do I calculate time and a half?

Multiply your normal hourly rate by 1.5, then multiply that figure by the number of overtime hours worked. For example, £14.50 × 1.5 gives an overtime rate of £21.75 per hour.

Does overtime count towards gross pay?

Overtime earnings will normally form part of your gross pay for the relevant pay period. Your final take-home amount can be lower after Income Tax, National Insurance, pension and other applicable deductions.

Overtime Pay for Public Sector Workers

How is overtime calculated for NHS staff?

NHS overtime rates can depend on your pay band, contract, working pattern and whether the extra hours are classed as overtime or enhanced hours. Check your employer’s local policy or terms and conditions, then use the calculator above with the multiplier that applies to you.

Do teachers get overtime pay?

Teachers are commonly paid an annual salary rather than a standard hourly overtime rate. Additional duties, cover, after-school activities or extra responsibilities may be handled differently depending on the employer and contract. Check your employment terms before using an overtime multiplier.

How is overtime paid for police officers?

Police overtime arrangements can vary depending on the force, role, rank, hours worked and the circumstances of the additional duty. Use the calculator above once you know the overtime rate or multiplier that applies to your shift.

Can council and local government workers use this calculator?

Yes. If your employer pays overtime using an hourly rate or multiplier, you can enter those figures into the calculator. If you need to work out your normal hourly pay first, use the WeFixPay Hourly Rate Calculator. Local authority overtime arrangements can differ, so check your contract or workplace policy first.

The Overtime Pay Calculator UK is designed to give you a quick estimate before deductions. Always compare the result with your employment contract, overtime policy and final payslip.
