Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take tax or fees or charges into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates for planning only. Prices, returns, inflation and personal circumstances all change. This is not financial or tax advice — speak to a qualified adviser before making decisions.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Which inflation rate should be used?

The category rate, not the general one. Education and healthcare inflate much faster than the headline index.

Should investment returns be included?

Yes for horizons beyond three years — they materially reduce the monthly saving needed.
