Round-Up Savings Calculator: How Much Will Spare Change Save You?
Free round-up savings calculator: enter how many card payments you make and we'll estimate how much spare change a round-up app like Plum, Monzo or Chip will save you in a year.
Round-up apps sweep the spare change from every card payment into savings, so a £2.60 coffee banks 40p. It feels like nothing, which is the point. Tell us how often you tap your card and we'll show you what that nothing adds up to in a year. The number of payments matters far more than how much each one costs.
Estimate your spare change for a year
We assume an average round-up of about 49p per payment to the nearest £1 (the mid-point of spare change), scaled up for £2 and £5 rounding. Contactless-only spenders tend to land a little higher because round amounts are rarer. Treat the figure as a realistic estimate, not a promise.
