Hourly to Salary Calculator

This page is for the moment when you already know the hourly rate and want to know what it means in real pay periods: weekly pay, monthly gross pay, and annual gross salary.

The main Hourly to Salary mode annualises the rate from your hours per week and paid weeks per year. The Part-Time mode uses the same hourly-first logic for reduced hours, while the Salary to Hourly mode is only there as a quick reverse check.

All outputs are gross pay before tax, pension contributions, benefits, overtime premiums, bonuses, or unpaid work time. Use the real hourly wage calculator when commute time and work costs matter, and use salary after tax when take-home pay is the real question.

At £15/hour for 20 hours a week, weekly gross pay is £300. Over 52 paid weeks that is £15,600 a year, or about £1,300 a month before tax and deductions.

At £18/hour for 30 hours a week, weekly gross pay is £540. Across 52 paid weeks that becomes £28,080 a year, or £2,340 a month gross.

At £25/hour for 37.5 hours a week, weekly gross pay is £937.50. Across a fully paid year, that is £48,750 annually, or £4,062.50 per month before tax.

Use 52 weeks when you are paid for the whole year, including paid leave or paid non-working weeks. Reduce the weeks per year if the hourly rate only applies to weeks you actually work.

This matters for part-time, seasonal, term-time, casual, and zero-hours arrangements. £20/hour can mean very different annual pay if it is paid for 52 weeks, 46 weeks, or only during busy months.

The monthly figure is annual gross pay divided by 12. It is useful for budgeting, but it is not a promise that every payslip will be identical if your hours change from week to week.

The calculator shows gross pay so the hourly-to-annual conversion stays clean. Tax, National Insurance or payroll taxes, pension contributions, healthcare deductions, benefits, and student loans can all change take-home pay.

Use the gross result as the first pass: what does this hourly rate produce before deductions? Then use a salary after tax or payroll calculator if the real decision depends on what lands in your bank account.

This page estimates regular annualised pay from the normal hourly rate, regular weekly hours, and paid weeks. It does not apply time-and-a-half, double time, shift premiums, holiday premiums, or legal overtime rules.

If extra hours are paid at a different rate, calculate the regular base pay here first, then use the overtime pay calculator for the premium hours.

Start with the hourly role because that is the known number: hourly rate multiplied by paid hours. Then compare the annual gross result with the salary offer.

A salary may include paid leave, steadier monthly pay, pension or retirement contributions, healthcare, and job security. An hourly role may make extra hours more visible. The calculator gives the common gross-pay basis, not the full employment package.

The core question is simple: if the rate is £15, £18, or £25 an hour, what does that become over the working pattern you actually expect?

The calculator annualises hourly pay by multiplying your rate by hours per week and paid weeks per year. That means a small weekly-hours difference can become a large annual difference.

Use 52 paid weeks for a year-round role with paid leave included. Reduce the weeks when work is seasonal, term-time, casual, unpaid during gaps, or only paid when shifts are available.

All results are gross pay figures. They do not include tax, pension deductions, benefits, bonuses, unpaid overtime, or employment-law overtime rules.

£15/hour at 20 hours per week gives £300 gross weekly pay. Over 52 paid weeks, that is £15,600 a year and about £1,300 per month before deductions.

£18/hour at 30 hours per week gives £540 gross weekly pay. Over a fully paid year, that is £28,080 annually and £2,340 per month gross.

£25/hour at 37.5 hours per week gives £937.50 gross weekly pay. Across 52 paid weeks, that is £48,750 per year and £4,062.50 per month gross.

£25/hour at 40 hours per week gives £1,000 gross weekly pay. Across 52 paid weeks, that is £52,000 per year and about £4,333.33 per month gross.

Comparing an hourly role with a salary offer without using the same weekly-hours assumption.

Leaving weeks per year at 52 when you are not paid for every week of the year.

Treating paid leave and unpaid holiday as the same thing. If leave is paid, it can stay inside the paid-weeks assumption. If it is unpaid, reduce the paid weeks or model the gap separately.

Treating the gross annual result as take-home pay. Use salary after tax or a payroll calculator when deductions are the main question.

This page estimates regular annualised pay. It assumes the entered hourly rate applies to the regular hours you enter.

If you work extra hours at the same rate, include them only if they are a normal part of the week you want to annualise. If extra hours are paid at time-and-a-half, double time, shift premium, or another custom rate, keep them separate.

Use overtime pay for premium hours, then combine the result with this page's regular gross pay if you need a fuller pay picture.

Use salary to hourly when the known number is an annual salary and you want to work backwards into hourly, daily, weekly, and monthly pay.

Use real hourly wage when commute time, tax estimates, unpaid work-linked time, and work-related costs could change the practical value of the job.

Use work hours when you need to establish paid hours from shifts and breaks before annualising the hourly rate.

Read salary vs hourly pay and the salary tax and take-home pay guide when the decision is about job structure, deductions, and what the headline number really means.

Rerun the calculation when your hourly rate, regular hours, paid weeks, or contract type changes.

Check the result again before comparing a permanent role with freelance, shift, seasonal, or part-time work.

Keep a note of the hours and weeks used so later comparisons are based on the same pay definition.
