To push spare change saving beyond modest amounts, try these acceleration strategies.
Stack round-ups with manual saves. Use automatic round-ups as your baseline, then add manual transfers whenever you resist an impulse purchase. Didn't buy that snack? Transfer £2 to savings manually on top of your round-ups.
Use multiplied round-ups. Monzo and some other apps let you multiply your round-up. A 3x multiplier turns a 60p round-up into £1.80. Over 100 monthly transactions averaging a 50p round-up, that's £150 a month instead of £50. Be careful though — monitor your balance to ensure multiplied round-ups don't cause overdraft issues.
Combine digital and physical. Run digital round-ups on card transactions AND save physical coins from cash transactions. This covers every payment method and maximises your catch.
Set up a 'spare change ISA'. Open a
cash ISA and periodically transfer your accumulated spare change savings into it. This way, your spare change not only grows but earns tax-free interest.
The 'keep the change' partnership. If you're in a couple, both partners run round-ups into a shared savings pot. Double the transactions, double the spare change, double the savings.
