Free GBP Budget Calculator

What is a GBP budget calculator?

A GBP budget calculator gives a quick check of whether your monthly plan leaves enough room after priorities.

Enter income, fixed costs, and savings contribution in pounds to estimate leftover monthly cash.

Leftover = Income − Fixed costs − Savings

Real-life example (try this in the calculator)

If income is £2,800, fixed costs are £1,200, and savings target is £350:

Line item Amount Calculator field
Monthly income £2,800 Monthly income
Fixed costs £1,200 Fixed costs
Savings target £350 Savings target
Monthly leftover is £1,250.

Use leftover to cover variable costs and extra financial goals.

How to read your results

  • Monthly leftover — Amount available after fixed costs and savings target.
  • Fixed + savings total — Combined committed spending plus savings.
  • Fixed cost share — How much of income goes to fixed obligations.

Re-check regularly if housing or utility costs change.
