Fixed Twig Bond — How Much Fits in a Hollow?

One opening deposit, one year, one rate. The twig stays fixed even when the wind gets ideas. The rate applies only to the initial 12-month term, with no promised renewal rate.

An acorn-shaped savings pot with coins.
A fictional bank, a real sense of humour. All people, places, products and figures are invented. No real banking or financial advice. About this demo.

Fixed Twig Bond is 12-month fixed savings in the Savings range, used for a known spending date one year away. Its live rate card, summary and worked tables sit above this text and update whenever the product record changes.

Know which amount the limit describes

For Fixed Twig Bond, the range is £1,000.00 to £100,000.00. For a savings product it is the opening and maximum principal; for an ISA it is the demo annual allowance; for a card or overdraft it is an assumed credit limit; for the mortgage it is an advance range; and for investments it is the minimum lump sum and any allowance. An interest credit may take savings just above the stated principal cap; further deposits then pause.

Before you increase the balance

CheckWhy it matters
MinimumAmounts below the model minimum do not qualify for this product scenario.
Maximum or allowanceProjection examples stay within the stated principal cap or demo allowance.
Already at the cap?Assume no further additions; accrued interest or growth is still credited.
Credit limitAvailable borrowing is a limit less debt already used, not income or savings.

The worked examples show the product-specific calculations and timing assumptions in full.

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.
