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.

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.

Really helpful app

Very useful for repeated “what if” questions.
Not failed me yet - since I originally found it on the Mac (now on iOS too of course).
Many thanks.

Update: After writing this review I realised that, having recognised just how useful it has been for me, I should make the small contribution asked for by the author. Now remedied - and I encourage everyone to consider it sooner than I did! :-)

Developer Response ,

Thanks for the great feedback. It's positive feedback like this that keeps me maintaining the app.

Excellent App

This really is a great app with an excellent amount of detail, especially student loan and pension that can be accessed and applied in a couple of taps.

Great to see the developer has really thought about the user experience.

Also sent a new feature request which was responded to in a couple of hours - brilliant support!!
