Hourly Calculator UK: Work Out Your Rate

This hourly calculator UK tool works out your pay for a given number of hours, or converts an annual salary into an hourly rate. You enter the amount (hourly, daily, weekly, monthly, or annual) and the hours you work per week, and it returns the equivalent figures in all common pay periods, including the UK tax year basis. Use it to compare job offers, check a contractor rate, or see what a salary really means per hour.

Formula

The core formula used here is simple division:

• Hourly rate = Annual salary ÷ (hours per week × 52)
• Weekly pay = Annual salary ÷ 52
• Monthly pay = Annual salary ÷ 12
• Daily pay = Hourly rate × 8 (assuming an 8-hour day)

Where:

• Annual salary – gross pay before tax, in pounds (£)
• Hours per week – contracted hours, typically 37.5 or 40 in the UK
• 52 – number of weeks in a year (ignores unpaid leave)

The calculator uses 52 weeks even though some years have 53 pay weeks – that is the standard convention for salary conversion.

Worked Example

Using the default values: annual salary £30,000, 37.5 hours per week.

1. Hourly rate = £30,000 ÷ (37.5 × 52) = £30,000 ÷ 1,950 = £15.38 per hour
2. Weekly pay = £30,000 ÷ 52 = £576.92 per week
3. Monthly pay = £30,000 ÷ 12 = £2,500.00 per month
4. Daily pay (8h day) = £15.38 × 8 = £123.08 per day

These match the calculator output (rounded to 2 decimal places).

When to Use This Calculator

Use this tool in several real situations:

• Comparing a salaried job with an hourly job – convert the salary to an hourly rate and see if it beats your current hourly wage.
• Contractor or freelancer rate setting – if you know your target annual income, work backwards to find your minimum hourly charge.
• Part-time work – a part-time salary is usually quoted annually, but you want to know the hourly equivalent to compare with full-time roles.
• Budgeting – knowing your monthly take-home (after tax) starts with knowing your gross monthly pay.

The calculator gives gross figures – before Income Tax, National Insurance, and pension contributions. Your take-home pay will be lower.

How to Read the Results

The first output, the hourly rate, is the headline number. It tells you what each hour of work is worth before deductions. The weekly, monthly, and daily figures help you plan cash flow.

Remember that the daily figure assumes an 8-hour day. If your day is 7.5 hours, multiply the hourly rate by 7.5 instead. The weekly figure assumes you are paid for 52 weeks – if you are a teacher or term-time worker with unpaid holidays, your actual weekly pay will be higher during working weeks.

All figures are gross. To estimate net pay, you would need to subtract tax and National Insurance – which depends on your tax code and personal allowance.

Common Mistakes and Misconceptions

• Using 52 weeks when you have unpaid leave – if you only work 40 weeks a year, your effective hourly rate is higher than this calculator shows. Divide annual salary by (hours per week × actual weeks worked).
• Confusing gross and net – the calculator outputs gross amounts. Your take-home pay is significantly less after tax and NI.
• Ignoring overtime – if you regularly work unpaid overtime, your real hourly rate is lower than the calculation suggests.
• Rounding too early – do not round the hourly rate before calculating daily or monthly figures; use the unrounded number for accuracy.
• Assuming a 40-hour week – many UK roles are 37.5 hours (NHS, civil service), some are 35, others 40. Use your actual contracted hours.

Limitations of the Formula

The formula assumes a fixed annual salary and a consistent weekly schedule. It does not account for:

• Overtime pay (usually time-and-a-half or double time)
• Shift premiums (night, weekend, bank holiday)
• Bonus or commission – these are extra, not part of the base salary
• Pension contributions (employer and employee)
• Student loan repayments
• Tax code changes

For a precise take-home figure, use a dedicated UK salary calculator that applies current tax bands and National Insurance thresholds. Those rates change each tax year, so always check the current figures.

Alternatives and Related Calculations

If you need more than a basic conversion, consider these related tools:

• Take-home pay calculator – includes tax, NI, pension, and student loan.
• Overtime calculator – works out pay for extra hours at a given multiplier.
• Freelance day rate calculator – converts a daily rate to annual income, accounting for non-billable days.
• Hourly to salary converter – the reverse of this tool: hourly rate × hours × weeks.

For most employees, the simplest way to check your hourly rate is to divide your annual salary by 52 and then by your weekly hours – exactly what this calculator does.

Frequently Asked Questions

Does the UK have a legal minimum hourly wage?

Yes, the UK has the National Living Wage and National Minimum Wage, which are set each April. The rates depend on your age and whether you are an apprentice. For 2024/25, the National Living Wage for workers aged 21 and over is £11.44 per hour. Always check the current rates on the official GOV.UK website, as they change annually.

How do I calculate my hourly rate from my monthly salary?

Multiply your monthly salary by 12 to get the annual figure, then divide by (hours per week × 52). For example, £2,500 per month × 12 = £30,000 per year. With a 37.5-hour week, that is £30,000 ÷ 1,950 = £15.38 per hour.

What is the difference between gross and net hourly rate?

Gross hourly rate is what you earn before any deductions. Net hourly rate is what you actually take home after Income Tax, National Insurance, and pension contributions. For a £30,000 salary, the gross hourly rate is £15.38, but the net hourly rate might be around £12.50 depending on your tax code and pension.

Do I include paid holidays when calculating my hourly rate?

Yes, if you are a full-time employee, your annual salary includes paid holiday (usually 28 days including bank holidays). The 52-week calculation automatically accounts for this because you are paid for those weeks even though you are not working. For zero-hours or casual workers, you only get paid for hours worked, so your hourly rate is simply your wage per hour.

How many hours per week is standard in the UK?

The average full-time working week in the UK is around 37.5 hours, but it varies by industry. Many office jobs use 37.5, retail often uses 40, and some sectors like hospitality use shift patterns. Always use your actual contracted hours for the most accurate calculation.

Is it better to be salaried or hourly paid?

It depends on your priorities. Salaried roles offer stability and paid holiday, but you may work unpaid overtime. Hourly roles pay for every hour worked, including overtime, but income can be unpredictable. Use this calculator to compare the effective hourly rate of a salary against an hourly wage to see which is better for you.
