UK Salary Calculator provides a simple numerical breakdown of your PAYE income, or a comparison of two different salaries. It is intended for use by residents, employers, and job seekers in the United Kingdom. Also available for MacOS.

Yearly, monthly, 4-weekly, weekly, daily and hourly breakdown of income tax, national insurance contributions, pension contributions, student loan, employer's national insurance contributions, company car tax, fuel benefit charge, child benefit, high income child benefit tax, gross salary and net salary. It calculates your overall effective tax rate and your marginal tax rate (the rate at which your next pound of earnings will be taxed at). The app is also compatible with the Scottish income tax system and accommodates the 5-tier tax rate structure.

It calculates your default tax allowance based on your age & income, and has facilities for adding additional allowances, customising student loan thresholds, adding salary sacrifices, modifying the numbers of days & hours you work, adding in childcare vouchers, marriage allowances, custom tax codes & deductions. It automatically reduces your personal allowance if you earn above the £100k income threshold.

UK Salary Calculator is fully reversible, meaning you can either enter your gross salary to see what your pay will be after deductions, or you can enter a net salary that you'd like to be your take home pay and UK Salary Calculator will tell you what you need to earn as a gross wage to make that happen. This app is therefore perfect for nannies, or individuals who employ a nanny, given their typical net-pay arrangements. It also caters for auto-enrolment pensions and has a setting to enable the lower/qualifying earnings limit threshold.

It is useful for employees and employers alike; whether you are looking to check your pay packet to ensure it's right, or to see what your earnings should/could be. It is also useful to see what your take home earnings will be in the next financial year or in another job. All calculations are based on data provided by HMRC and the Student Loan Company.

The company car tax feature allows you to input your car's P11D value & CO2 emissions and the app will automatically calculate the appropriate tax deductions and fuel benefit charge, if required.

Salary sacrifices, allowances, and deductions can be input on a £'s/Year, £'s/Month, £'s/4-Week or £'s/Week basis. Pension can be added as a percentage or an amount.

Results are easily shared and exported via email.

Still brilliant …

I left a five star review around five years ago and I’ve not had the need, nor been tempted to, try any other similar app. This has always been accurate to within pennies of my actual take home pay. I now have two part time jobs with very different pension arrangements and tax codes but it handles both with a breeze, developer(s) certainly know their stuff. Anyway I felt this app duly deserves another 5 star review as with the raid on our salaries about to happen more people may be looking for this sort of thing; they don’t get more accurate, detailed and user friendly than this. Don’t be put off if the tax year 22/23 is not showing just yet, developer has always updated it in a timely manner and there’s still a month to go at the time of writing!

Developer Response ,

Thanks very much for the great review Joey - new FY update will be released in just a few days! Cheers

Different from desktop version

I was impressed with the flexibility of the desktop version and downloaded this iOS version to have for easy access. However, unlike the desktop version, this version does not give the option to include a second income. My motivation for this was to assess the effect of salary over and above my existing pension income, which it does on the desktop version.

Superb - the only UK app that does what I need

It’s a rarity I leave any reviews never mind a 5-star review. However this app is excellent, flexible, accurate….it does exactly what I need and I’ve downloaded plenty of apps in this salary/tax category. And the support is second-to-none….its all personally managed and really helpful.
Don’t waste your time with any other app - get this one.
