How It Works

Overtime Pay Explained

The most common overtime structures used across the UK, US, and beyond.

⏰

Time and a Half (×1.5) — Police & Emergency Services

The most common rate for police officers, paramedics, and private sector workers. For every overtime hour worked, you earn 1.5 × your base rate. For police specifically, this often kicks in after the first 30 minutes of casual overtime.

➕

Time and a Third (×1.33) — NHS & Healthcare

Standard for many NHS roles and public sector contracts. If you're a nurse or care worker, additional hours or unsocial shifts often attract this rate. A £20/hr base rate becomes £26.60/hr for these overtime hours.

⚡

Double Time (×2.0)

Often applies on bank holidays or Sundays. You earn exactly 2 × your base rate. A £14/hr base means £28/hr for these hours.

🔧

Custom Rates

Many contracts have different rates for evenings, nights, or weekends. Use the Custom option above, or let the Overtime Live app handle split-rate shifts automatically.

Note for Frontline Workers: Whether you are on NHS Agenda for Change or Police Federation rules, tracking these specific 'extra' minutes is where most pay errors occur. The Overtime Live app was designed to handle these exact shift patterns.
FAQs

Common Questions

Multiply your hourly rate by 1.5. So if you earn £15/hr, your time-and-a-half overtime rate is £15 × 1.5 = £22.50/hr. Then multiply that by the number of overtime hours worked to get your overtime pay total.
Overtime is any time worked beyond your contracted hours — typically anything over 37.5 or 40 hours per week in the UK. Your employment contract will specify the exact threshold and what rate applies. Some roles (NHS, police, security) have specific union or pay-scale agreements.
Under the UK Working Time Regulations, you cannot be forced to average more than 48 hours per week over a 17-week reference period — unless you voluntarily sign an opt-out agreement. Many shift workers in healthcare, emergency services, and logistics do sign such opt-outs.
Overtime pay is taxed in the same way as your regular salary — under PAYE in the UK. If extra overtime earnings push your total pay into the higher rate band (40%) for a given pay period, HMRC may deduct more tax that month, though this often corrects itself across the year.
Gross pay is the total before any deductions. Net pay (take-home) is what actually lands in your bank account after income tax, National Insurance, pension contributions, and any other deductions. Expand the tax section above to estimate your take-home.
