Salary Calculator

What Is a Salary Calculator?

You've been offered £38,000. But what does £38,000 actually mean when the rent goes out on the first of the month? Divide by 12 and you get a gross monthly figure — before income tax, National Insurance, and any pension contribution. Most people don't know their actual take-home until the first payslip lands.

The UK median salary sat at around £34,963 in 2024 according to ONS data. London skews considerably higher; Wales and the North East sit well below. Standard full-time hours are usually 37.5 per week, but contracts vary — 35, 40, or anything in between. This calculator lets you set your actual weekly hours so the hourly equivalent comes out accurately, not based on an assumed 40-hour week.

Enter your annual salary and contracted weekly hours. You get the full breakdown: yearly, monthly, weekly, daily, and hourly rates. Adjust the salary figure to compare job offers side by side, or work backwards from a target hourly rate to find the annual equivalent.

How Does the Salary Calculator Formula Work?

The formula used: Hourly = Annual / (Working weeks × Hours per week). Monthly = Annual / 12

What Are Some Example Calculations?

An annual salary of £35,000 with 37.5 hours/week: Monthly = £2,916.67. Weekly = £673.08. Daily = £134.62. Hourly = £17.95.

When Should You Use a Salary Calculator?

When evaluating a job offer, convert both roles to an hourly rate. A £40,000 salary on a standard 37.5-hour week pays £20.51 per hour. The same salary requiring 45 hours a week pays £17.09. Same headline number, very different reality — and that gap is what the hourly conversion reveals.

Freelancers and contractors: use this to set your day rate. Take your target annual income, add 25–30% to cover unpaid holiday, sick days, and the employer contributions you now fund yourself, then divide by your working days. A £35,000 equivalent permanent role should translate to roughly £200–£220 per day as a contractor to match like for like.

How Do the Options Compare?

What Are the Best Tips to Know?

• Compare job offers using the hourly rate rather than the annual figure to account for different working hours.
• Add employer pension contributions to the total package value before comparing offers.
• Freelancers: multiply your equivalent hourly rate by 1.25 to account for unpaid holidays and sick days.
• Check your payslip monthly to verify the gross-to-net deductions match your tax code.
• Use the hourly rate as a baseline when negotiating overtime or freelance side work.

What Mistakes Should You Avoid?

• Comparing gross salaries without accounting for different pension contribution rates between employers.
• Forgetting that a higher salary may push income into the next tax band, reducing the net gain.
• Using 365 days instead of 260 working days when calculating the daily rate.
• Ignoring benefits such as health insurance, car allowance, and bonus schemes when comparing total compensation.
