About this estimate
This figure compounds monthly at a fixed 3% annual rate for the full 10 years, with no further contributions and no tax taken into account. Real investment and savings returns vary year to year rather than staying fixed, and most savings interest is covered by the Personal Savings Allowance - but larger balances or investments held outside an ISA may have tax to pay.
