Open toolOverview
The money calculators are built for practical household and planning questions: what comes home each month, how pension sacrifice changes pay, how capital gains might be taxed, how savings might grow, and how long a mortgage or FIRE target could take.
Where UK tax-year rules matter, the tools expose the selected rules year and explain the assumptions used. The outputs are designed for comparison and planning, not as regulated financial advice.

Tools that depend on tax rules expose the current rules year and recent years where the calculator supports that comparison.
Salary sacrifice, pension forecast, ISA, compound growth, Capital Gains Tax, and FIRE tools are natural next steps because they use the same income, tax, and savings assumptions from different angles.
