About What’s Left
Free calculators for people paid a salary, paying rent, or thinking about a mortgage. Type numbers in. Get a straight answer.
It is not a bank. There is no login, no Open Banking, and we do not look at your accounts. It is not for limited companies, sole-trader tax, payroll or invoices.
Figures are estimates. Tax rules change. Nothing here is financial advice.
The tools
- Take-home pay — See what actually lands in your account after tax, NI, student loan and pension.
- Monthly budget — Line up bills and spending against take-home, and see what is left.
- Debt payoff — Avalanche or snowball: a payoff order, months to clear, and interest.
- Emergency fund — How many months of essentials you could cover, and the gap to target.
- Rent or buy — A sniff test: monthly rent versus a rough mortgage repayment. Not an offer.
- Bills converter — Turn weekly, 4-weekly, quarterly and yearly bills into honest monthly totals.
