Coffee Cost Calculator
See what your daily bought-coffee habit really costs — weekly, monthly and per year — and what switching to home-brew or investing the saving could be worth. A £3.35 weekday coffee alone adds up to about £871 a year.
Estimate only. This calculator gives estimates for information only, not financial advice. The invested-instead projection is illustrative — investment growth isn't guaranteed and actual returns will vary.
Redirecting £73/month into an investment growing at your chosen rate could add up to:
Grown from £8,710 paid in, plus £2,561 in growth.
| Years | Paid in | Total value |
|---|---|---|
| 10 | £8,710 | £11,270 |
| 20 | £17,419 | £29,833 |
| 30 | £26,129 | £60,405 |

- Bring a reusable cup — most UK coffee chains knock 25–50p off for using your own.
- Buy beans from a cash-and-carry or wholesaler and brew at home — it can cost as little as 30p a cup.
- Batch-brew a flask in the morning instead of buying on the way to work or the school run.
- Use loyalty apps and stamp cards — many chains offer a free coffee after 9 paid ones.
Why a coffee habit costs more than it feels like
A single bought coffee doesn't feel expensive in the moment, but multiplied across a working week and a full year, small daily spending adds up fast — this is sometimes called the "latte factor". At the UK average price of £3.35, one weekday coffee comes to roughly £871 a year; two a day, five days a week, is nearer £1,742. Switching to home-brew — or investing the difference instead — can turn that everyday spend into a meaningful long-term saving.
