Assumptions: one opening deposit, no additions or withdrawals, no fees or tax, and the stated rate for the whole period. Interest is credited once at each anniversary and rounded to the nearest penny, with half-pennies rounded up. AER and gross p.a. match in this annual-credit model.

The variable rate is held constant solely to show annual compounding. These are scenarios, not forecasts; a future rate change would change every later row. Figures are before inflation.
Golden Tail Retirement is later-life cash savings in the Investments range, used for a cash reserve for a slower pace of life. Its live rate card, summary and worked tables sit above this text and update whenever the product record changes.
Adding money to the example
For savings, a deposit increases the principal from the time it arrives; it does not earn a full year of interest if it arrives halfway through the year. A fixed product accepts its single opening deposit only, and an ISA wrapper counts new money against the demo annual allowance. For investments, each contribution buys units at that month’s value. For borrowing products, paying money in is a repayment that reduces debt, not a savings deposit.
See the whole Investments range or compare every product on the rates page.
What the example does not promise
All figures are invented and shown to make the demo useful to read and crawl. No money is held, no application is available, and no deposit-protection, regulatory or tax-wrapper status is claimed. Calculations do not account for personal tax, inflation or unstated changes in rates. The fictional bank manager can guarantee only that the next paragraph contains no real acorns.
