How to work out shift pay

Start with paid hours, not scheduled hours

A shift from 8am to 4pm is eight hours on site. It is only eight paid hours if every break is paid. If it includes a 30-minute unpaid break, the paid time is 7.5 hours. That is the first figure to multiply by the hourly rate.

Use the Shift Pay Calculator for a quick gross-pay estimate from an hourly rate, shift length, unpaid break and uplift.

Check whether an uplift applies to all hours

Night, weekend and bank-holiday work can be paid with a percentage uplift, a different hourly rate or a flat allowance. The wording matters. A 25% uplift on GBP 12 per hour gives GBP 15 per hour. It is not an extra GBP 25 an hour.

Some contracts apply the enhancement to every paid hour in a shift. Others apply it only after a set time, only to particular days, or only when the shift meets a minimum length. Check the rota, contract or payroll note before treating one percentage as universal.

Keep overtime separate

Overtime may use a different rule from a shift uplift. For example, a worker could receive a weekend uplift for normal rostered hours, then time-and-a-half only after working more than their contracted weekly hours. Adding all extra money as one rate can hide an error.

The Hourly Pay Calculator lets you show regular pay and overtime as separate lines. That is more useful where the number of extra hours changes each week.

Weekly and yearly figures are projections

One shift amount is straightforward. Weekly, monthly and annual totals assume a repeatable pattern. A five-shift week at the same rate can be multiplied by 52 for a broad yearly projection, but this may not suit seasonal work, unpaid shutdowns, agency work, changing rotas or term-time roles.

Holiday pay, sick pay, deductions, pension, tax and National Insurance are also separate questions. Gross shift pay is not the same as take-home pay.

A simple checking order

1. Write down the scheduled start and finish time.
2. Remove unpaid breaks.
3. Multiply paid hours by the base hourly rate.
4. Add the correct uplift or allowance.
5. Keep overtime and one-off payments on separate lines.
6. Use the gross weekly amount as the starting point for a take-home estimate.

This makes it much easier to compare a job advert, rota and payslip without guessing which rule changed the result.
