How the calculation works

Set-aside = revenue × set-aside rate. Illustrative tax = max(revenue − set-aside − expenses, 0) × tax rate. Remaining revenue = revenue − both set-asides.

A worked example

For VAT arithmetic, adding 20% to £100 gives £120, including £20 VAT. Removing 20% VAT from £120 gives £100 net and £20 VAT.

What to allow for

  • The optional planning mode uses a percentage set-aside. Setting aside 20% of revenue is not the same as removing 20% VAT from an inclusive price.
  • Add VAT uses net amount × (1 + rate). Remove VAT uses gross amount ÷ (1 + rate). These modes do not estimate income tax.
  • VAT on purchases, VAT schemes, registration, agent/principal status, tax bands and reliefs are outside this calculator. Use an accountant for your actual liability.

Useful questions

Which mode should I use?

Use Add VAT for a price that excludes VAT, and Remove VAT for one that includes VAT. Use Revenue set-aside for a budgeting scenario.

Does the planning result include expenses?

The headline is before expenses are paid. The breakdown also shows the balance after those expenses so the two figures are not confused.
