Income tax and National Insurance are different
The 2026/27 take-home pay tool models employee NI and income tax under a standard employment scenario, with a Scotland selector. Your actual tax code, pension salary sacrifice, student loan and payslip period can change the outcome.
Use the repayment tool for regular monthly principal-and-interest cost. Use the separate overpayment calculator to see how maintaining your normal monthly payment while paying extra may shorten a mortgage. It does not automatically compute your lender's annual overpayment allowance or early repayment charge.
PCP may show a low monthly payment while leaving a substantial final balloon if you want to own the car. The PCP page compares that mathematical ownership cost with a conventional no-balloon credit scenario, but cannot reproduce mileage or vehicle-return conditions.
The pension tool grows personal and employer contributions as an illustrative investment pot. A State Pension forecast depends on your National Insurance history and transitional rules; use GOV.UK for the official personalized forecast.
