Hazelnut Fixed Cash ISA in charts
The same fictional model as the tables below, drawn rather than written. Hover or focus a mark for its value, or open the table view.
Interest credited annually and rounded to the penny; figures exclude tax unless the wrapper is tax-free.

| Category | Interest |
|---|---|
| £1,000 | £43.00 |
| £5,000 | £215.00 |
| £10,000 | £430.00 |
The deduction never exceeds the interest earned, so the deposit itself is always returned.

What could your balance look like after 12 months?
| Opening deposit | Demo AER | Interest earned | Closing balance |
|---|---|---|---|
| £1,000.00 | 4.30% | £43.00 | £1,043.00 |
| £5,000.00 | 4.30% | £215.00 | £5,215.00 |
| £10,000.00 | 4.30% | £430.00 | £10,430.00 |
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 ISA wrapper means the model deducts no tax from the interest.
The projection stops at 12-month maturity. No rate is promised beyond that date. Reinvestment would require a new fictional product and new terms.
Closing a £10,000.00 deposit early
| Closed after | Interest accrued | 90-day deduction | Interest paid | Amount returned |
|---|---|---|---|---|
| 3 months | £107.21 | £106.03 | £1.18 | £10,001.18 |
| 6 months | £215.59 | £106.03 | £109.56 | £10,109.56 |
| 9 months | £322.79 | £106.03 | £216.76 | £10,216.76 |
Early closure costs 90 days’ interest in the model, calculated on the deposit at the fixed rate using simple daily accrual. The deduction never exceeds the interest earned, so closing very early returns the deposit with no interest rather than less than the deposit.
Using the demo ISA allowance
| New money in the demo tax year | Allowance used | Allowance remaining |
|---|---|---|
| £10,000.00 lump sum | £10,000.00 | £10,000.00 |
| £200.00 a month for 12 months | £2,400.00 | £17,600.00 |
| £10,000.00 lump sum plus £200.00 a month | £12,400.00 | £7,600.00 |
The demo allowance resets each fictional tax year and is shared across every ISA a story customer holds. Money cannot be withdrawn during the fixed term; a transfer out is treated as early closure.

Meet your next imaginary account
The purpose of Hazelnut Fixed Cash ISA is a year of tax-free interest at a fixed rate. 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.
