Quick calculators built for UK households. No sign-up needed, and the maths runs in your browser.
What you take home, and how to keep more of it.
Your pay after tax, National Insurance, student loan and pension, worked out month by month like payroll. Checks your tax code, shows your bonus month, what's settled after the tax year, and what a pay rise or another job is really worth.
Open calculator →What sacrificing salary or a bonus into your pension really saves, against paying in yourself or taking it as pay. Counts National Insurance, your employer's match and NI saving, student loans, the Child Benefit charge and the £100,000 trap, and shows what the 2029 cap changes.
Open calculator →Your mortgage, and whether to pay it off faster.
Your monthly payment and total interest, plus what a lump sum or regular overpayment saves you. Want more equity before your next remortgage, or to be mortgage-free by a certain year? Set the balance you're aiming for and when, and it works out how much to overpay.
Open calculator →Should the spare money go into your mortgage, or into savings, an ISA, a general investment account or your pension? Compares all five after UK tax, including the changes already announced.
Open calculator →Pensions, savings and family planning tools are next. Got one you'd like to see? Tell us.
