Your week, hour by hour
40 basic hours at £15.00 make £600.00. 6 at time and a half (£22.50 an hour) add £135.00 and 2 at double time (£30.00 an hour) add £60.00. That is £795.00 for 48 hours, or £16.56 an hour on average.

Each column is one hour, as tall as what it pays. The minimum wage is checked on the average across every hour in the pay reference period (a week here, up to a month for monthly pay), overtime included.
What the law says about overtime pay
The multiplier is a contract choice. These four aren't. For the minimum wage at every age, use the minimum wage calculator.
UK law sets no premium for overtime. Time and a half, double time or plain time: the rate is whatever the contract says. An employer doesn't have to pay for overtime at all, as long as the average pay for every hour worked stays at or above the minimum wage.
GOV.UK: Overtime payThe National Living Wage for workers aged 21 and over from 1 April 2026. It is checked on total pay divided by all the hours worked in the pay reference period (the week or month they're paid for, never more than 31 days), overtime included. A good basic rate can still fail it once unpaid hours are added.
GOV.UK: Calculating the minimum wageHoliday pay for the first 4 of the 5.6 weeks of statutory leave includes overtime the worker does regularly, whether it is guaranteed, compulsory or voluntary. When pay varies, it is averaged over the last 52 weeks they were paid.
GOV.UK: Holiday payOvertime counts towards the 48-hour average week, taken over 17 weeks, unless the worker signs an opt-out. They can cancel it with at least 7 days' notice, or up to 3 months if their written agreement says so.

From the calculator to every payslip
This calculator gives you the numbers. TimeTally tracks hours, approvals, and overtime automatically — so you never need to calculate it manually again. From £3/employee/month.
Set once, for the whole team
Overtime can start after a number of hours a day, a week or a month, after each person's own working pattern, or outside set times of day. Pay it at a multiple of each person's rate, like 1.5×, or at a fixed £ rate, add higher levels on top (double time after 45 hours, say), or bank it as time off in lieu instead.
Staff submit timesheets via the iPhone or Android app, or web. Clock in/out is tracked automatically. Regular and overtime hours are separated — no paper forms, no chasing.
All pending timesheets land in your dashboard. Approve or reject with a single tap. Every decision is timestamped — full audit trail for every timesheet.
Pay is calculated directly from approved timesheets. Overtime rates applied automatically. Regular and overtime hours separated — no manual adjustments, no errors.
Approved timesheets feed directly into your payroll export. Direct integration with Xero and QuickBooks — no manual data entry, no missed overtime.

Overtime that works itself out.
Two triggers: threshold overtime kicks in once an employee exceeds a set number of hours per day or week. Time-of-day overtime pays a premium for hours worked in a specific window (e.g. after 6pm or before 6am), regardless of total hours. Two pay methods: a rate multiplier (e.g. 1.5×) or a fixed hourly rate for overtime hours. Stack multiple rules, build tiers, and configure each employee independently.
Know exactly where the hours went.
Entirely optional — only enable it if you need it. When on, employees split their hours across projects when submitting (e.g. 3h on Client A, 4h on internal work). You can set project pay for the worker: an hourly rate on top of or instead of their usual rate, or a flat fee per entry (useful for callouts or site visits). Managers get a clear breakdown of where time is actually going.
Offer time off instead of overtime pay.
An optional alternative to paying overtime — enable it only if you want to offer time off in lieu instead of (or alongside) extra pay. Set a TOIL conversion rate (e.g. 1h overtime = 1.5h leave) and overtime hours automatically accrue as a TOIL balance — no manual tracking. TOIL is kept separate from annual leave so it never eats into holiday entitlement. Employees book it the same way they book any other leave.
Approve a whole week from your phone.
Managers approve or reject timesheets from any device — phone, tablet, or desktop. Rejections include a written reason so employees know exactly what needs fixing and can resubmit. Managers can see who has not submitted for the period, and are emailed as each timesheet comes in. Pay totals are calculated automatically from approved hours — no manual maths at payroll time.
Clock in, or fill in a form.
Two submission modes — employees use whichever fits their workflow. Clock-in mode starts a live timer the moment they begin their shift. The timer runs in the background even if the app is closed, so no hours are lost. Form mode lets them enter start time, end time, and breaks at the end of the day or week. Both work on mobile and desktop.
Every hour costed at the right rate.
Set each employee's own hourly rate and pay totals are calculated automatically from their approved hours. Scope managers to their department so they only ever see their own team's data. Want to keep salaries private? Hide pay rates and totals from managers entirely — they see hours, but never figures. Full control over who sees what.
Straight into Xero or QuickBooks.
Send approved timesheets to payroll in a few taps. Export to CSV, Xero, or QuickBooks — filter by date range, employee, or department, and choose exactly which columns to include. You can combine timesheet and leave data in a single export so your payroll software gets everything it needs in one file.

No. UK law does not require employers to pay a premium rate for overtime. There is no statutory right to time-and-a-half or double time. Overtime pay is governed by what is stated in the employment contract. However, the total pay divided by total hours worked must never fall below the National Minimum Wage (£12.71/hour for workers aged 21+ from April 2026).
Multiply the employee's standard hourly rate by 1.5. For example, if an employee earns £15/hour, their time-and-a-half rate is £15 × 1.5 = £22.50/hour. For overtime hours, multiply the number of overtime hours by this rate to get the overtime pay.
Double time means the employee is paid twice their normal hourly rate for overtime hours. If an employee earns £15/hour normally, double time is £30/hour. Double time is typically reserved for bank holidays, Sundays, or extended overtime in sectors such as construction and healthcare.
Convert the annual salary to an hourly rate first: divide the annual salary by 52 (weeks), then divide by contracted weekly hours. For example, a £30,000 salary with 37.5 contracted hours gives £30,000 ÷ 52 ÷ 37.5 = £15.38/hour. Then apply the overtime multiplier to this rate.
Yes — for workers who regularly work overtime. Following the Bear Scotland and Flowers cases, regular voluntary overtime must be included when calculating holiday pay for the first 4 weeks of statutory leave. Guaranteed and non-guaranteed overtime must also be included.
Under the Working Time Regulations 1998, workers cannot work more than an average of 48 hours per week (including overtime) over a 17-week reference period, unless they have signed a written opt-out agreement. Workers can withdraw their opt-out at any time by giving the notice period specified in the agreement (up to 3 months).
Only if your employment contract includes a compulsory overtime clause. Your employer cannot force you to work overtime that is not in your contract. If overtime is voluntary, you have the right to refuse. Check your contract — it should state whether overtime is compulsory, the rate at which it is paid, and how much notice you will be given.
TOIL is when an employer offers paid time off instead of overtime pay. For example, if you work 2 extra hours on a Saturday, you might receive 2 hours of paid time off to take later. TOIL is not a legal requirement — it is only available if your employment contract allows it. The rate at which TOIL accrues (e.g. 1:1 or 1.5:1) should be specified in your contract.
For irregular hours workers, first calculate the hourly rate for the hours actually worked. If the contract specifies an overtime threshold (e.g. anything over 8 hours per day or 40 hours per week), count the hours above that threshold as overtime and apply the agreed multiplier. For zero-hours workers, overtime typically only applies if the contract specifies a minimum hours threshold.
Yes. Even if overtime is unpaid or paid at a reduced rate, the total pay divided by total hours (including overtime hours) must never fall below the National Minimum Wage. For workers aged 21+, the NMW is £12.71/hour from April 2026. If overtime brings the effective hourly rate below this, the employer is breaking the law and HMRC can impose back pay and penalties.
