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 projection stops at 12-month maturity. No rate is promised beyond that date. Reinvestment would require a new fictional product and new terms.

Meet your next imaginary account

The purpose of Fixed Twig Bond is a known spending date one year away. Start with the access rules, then compare the cost or return with your story’s timescale. A higher headline figure does not make a locked account suitable for an immediate bill, and a reward percentage is not the same as an interest rate.

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.
