UK Salary Calculatoris a free iPhone application developed by Costrak Ltd. It is a convenient tool for individuals in the UK to calculate their salary figures under the UK PAYE system. The calculator accurately determines the tax to be paid, known as PAYE, as well as the employee's national insurance contribution (NIC).

One of the key features of the UK Salary Calculator is the option to input your tax code, if known, which is used to calculate the PAYE tax due. Additionally, if you have a student loan, the calculator allows you to select between student loan plan 1 or plan 2, and calculates the expected deduction from your salary accordingly.

The calculator provides calculated figures for PAYE, National Insurance Contributions (NIC), student loan repayments, and take-home pay on a yearly, monthly, weekly, and daily basis. It presents a comprehensive breakdown of deductions from the gross salary to give an estimated take-home pay.

Please note that the calculator currently does not handle Scottish tax bands. However, it offers four calculators to cater to various needs: the take-home pay calculator, net salary to gross calculator, furlough pay calculator, and pro-rata pay calculator. The hourly pay calculator is also available, allowing users to input their hourly rate and working hours to estimate their take-home income after deductions.

Overall, UK Salary Calculatoris a valuable tool for individuals in the UK to accurately calculate their salary figures under the PAYE system, providing comprehensive breakdowns and estimates on various aspects of their income.
