Zero Nut Zone Card — Rates and Returns

Nothing to pay in interest for eighteen months, provided the balance is gone before the zone ends. The tables show the monthly amount that clears a purchase in time and what happens to any nut left behind.

A fan of acorn-branded bank cards.

Offer assumptions: every payment is made on time, no cash withdrawals or transfers, and nothing else is spent. A missed payment ends the 0% period in the model and the standard rate applies to the whole balance from then on.

Borrowing assumptions: one £1,200.00 opening balance, no new spending, no fees or cashback, and 24.9% APR held constant. The equivalent monthly rate is (1 + 0.249)^(1/12) − 1. Interest is rounded monthly; eleven equal payments are followed by an adjusted final payment. Total repaid: £1,350.82; total interest: £150.82. This chosen repayment plan is not a minimum-payment schedule. Reward and offer tables describe separate situations from this one.

Zero Nut Zone Card is 0% purchase credit card in the Credit cards range, used for spreading a planned purchase over 18 interest-free months. Its live rate card, summary and worked tables sit above this text and update whenever the product record changes.

Rewards, offers and the cost of borrowing

A cashback rate, a 0% period and an APR are three different measures. Cashback is paid on eligible spending that is repaid in full; a 0% offer defers interest for a fixed number of months and ends with a missed payment; the APR is what borrowing costs once interest applies. The tables show each one separately so that a perk is never mistaken for a return.

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.
