Planning routes

Work from today's pay to longer-term choices

Start with the number you are trying to understand: monthly pay, a pay rise, pension sacrifice, a savings target, a mortgage payment, or a tax bill. The calculators keep the important assumptions visible so you can compare scenarios without losing the headline answer.

UK tax-year rules, allowances, pension assumptions and investment inputs are shown where they affect the result. The outputs are planning estimates, not regulated financial advice.

Considering salary sacrifice?

Use Salary Sacrifice to see the take-home impact, then Pension Forecast to understand how larger pension contributions might affect the long-term projection.

Checking a pay rise?

Start with Pay Rise to compare before and after deductions, then use Take Home Pay Bands if you want to see how the same salary sits against nearby earnings levels.

Testing savings and tax outcomes?

Use ISA and compound growth for longer-term scenarios, then check whether a disposal could create a Capital Gains Tax estimate.

What matters

Money outputs should show the trade-off, not just a number

  • Pay and tax tools show gross pay, deductions, take-home pay, allowances and pension effects.
  • Long-term planning tools connect ISA, pension, compound growth, FIRE and mortgage assumptions.
  • Planning tools connect ISA, compound growth, FIRE, fuel prices and Capital Gains Tax scenarios without hiding the assumptions.

FAQs

Money Calculator Questions

Which UK tax year do the pay calculators use?

Tax-sensitive calculators show the rules year they use, and some let you choose recent years for comparison.

Can I model salary sacrifice and pension effects together?

Yes. Salary Sacrifice shows the pay impact, while Pension Forecast helps you explore the possible longer-term pension effect.

Are these calculators financial advice?

No. They are planning estimates to help you understand scenarios before checking payroll, tax, pension, mortgage, or investment decisions against official guidance or professional advice.
