Overview
- Opting in through the app creates a Challenge Pot that moves rising daily amounts from 1p to £3.65, reaching £667.95 by year‑end if completed.
- Completers qualify for a £10,000 draw, with entry requiring a Monzo personal account, UK residency, age 18 or over, a start before 31 January 2026, and £667.95 in the pot excluding interest on the final day.
- Customers on Extra, Perks or Max can choose 2x or 4x starting amounts, earn 5% interest on their Challenge Pot and enter monthly £100 prize draws for 100 winners, with the 4x path totalling up to £2,671.80.
- Monzo says 1.7 million people joined the challenge in 2025, saving over £360 million by November, and the app lets users pause, stop or make up missed days.
- MoneySavingExpert and banks such as NatWest share manual and monthly variants so non‑Monzo users can follow the plan via transfers or cash jars.
