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.

| 5 | £217.25 | £6,010.50 | £1,010.50 |
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.
Squirrel Saver is easy-access savings in the Savings range, used for a first home for spare savings. Its live rate card, summary and worked tables sit above this text and update whenever the product record changes.
Understand the headline rate
Savings AER expresses annual interest including compounding where relevant; gross means before tax and tax-free means the demo ISA wrapper deducts none. APR and EAR describe borrowing costs on different stated bases. Cashback and 0% offers are perks on qualifying activity, not interest on a balance. Compare matching measures and read the assumptions below before comparing the numbers.

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.
