Coffee Cost Calculator
Find out how much you spend on coffee per year and whether switching to home brew would save you money.
I built this because the annual cost of a daily coffee habit surprised me. It is not about judging the habit — it is about seeing the number and deciding consciously rather than by default.

The coffee cost calculator shows how much you spend on café coffee each year and what you would save by switching to home brew. Enter how many cups you buy per day, your average cost per cup, what home-brewed coffee costs you, and how many days a year you actually buy out. The result is your annual spending, your potential saving, and the five-year total. Coffee spending is easy to underestimate because each transaction is small. Two cups a day at £5, over 250 working days, is £2,500 a year, and that is before the weekend flat white. Set against home brew at 50p a cup over the same 250 days, which is £250, the gap is £2,250. Those are illustrative prices. Your own numbers matter more than anyone's average, which is why every field is editable. None of this is an argument to give up café coffee. That is a decision about enjoyment, convenience and how you like to spend a morning, and the calculator only supplies the figure you are trading away. Some people see the total and carry on exactly as before. Others move half of it into savings.

How It Works
Annual Spend = Cups/Day × Cost/Cup × Days/Year
Formula: Annual Café Spend = Cups Per Day × Cost Per Cup × Days Per Year Annual Home Cost = Cups Per Day × Home Cost Per Cup × Days Per Year Annual Saving = Annual Café Spend − Annual Home Cost Example: 2 cups a day at £5 each, 250 days a year, with home brew at £0.50 a cup. Café annual = 2 × £5 × 250 = £2,500 Home annual = 2 × £0.50 × 250 = £250 Annual saving = £2,500 − £250 = £2,250 5-year saving = £2,250 × 5 = £11,250 The home brew figure should include the machine, spread over its life. A £300 espresso machine making 3 cups a day for three years works out at about 9p a cup in equipment, and an 18g dose from a £6 bag of 250g beans is roughly 43p, so about 50p a cup all in. That is the default used here. Change the home cost field if you brew differently: filter or cafetière usually lands around 25p to 40p a cup, and pod systems around 45p to 80p depending on the pod.
Frequently Asked Questions
How much does the average person spend on coffee per year?
There is no UK figure here we would be comfortable quoting. The averages that get repeated online are usually American, or come from surveys with no published method, so the arithmetic is the more honest answer. One £3.50 coffee on 250 working days is £875 a year. One £4.50 coffee on the same pattern is £1,125. Two £4.50 cups a day comes to £2,250. Brewing two cups at home for about 50p each costs roughly £365 across a full year, weekends included. Put your own prices into the calculator and the number will actually apply to you.
Is it worth making coffee at home to save money?
On money alone, yes. At the calculator's defaults, two £5 café cups over 250 days is £2,500 against £250 of home brew, a difference of £2,250 a year. Even a single £4 coffee on workdays is £1,000 against about £125 at home. Whether the trade is worth making depends on what the café is actually giving you. For plenty of people it is the walk and ten minutes away from a desk, and no machine at home replaces that. A split suits most: brew on weekday mornings, keep the café for when you want to sit in one.
What is the cheapest way to make coffee at home?
A cafetière or a filter brewer. A cafetière typically costs £10 to £25 and a decent filter machine £30 to £60, and with a £6 bag of 250g beans you are looking at roughly 25p to 40p a cup depending on your dose. An AeroPress sits in similar territory. Espresso machines cost far more up front, but once the machine is spread over a few years of daily use the per-cup cost lands close to filter. Pods are the expensive end of home brewing: convenient, but several times the cost of loose beans per cup.
How much does a Nespresso cost per cup vs a café?
Original Nespresso capsules are usually somewhere around 40p to 55p each, Vertuo pods run higher, and supermarket compatible pods undercut both. Prices move, so check before relying on those. Add milk for a latte and a pod drink at home lands near 60p to 75p. A high street latte is commonly £3.50 to £4.75, so every pod drink you make instead saves roughly £3, or about £750 over 250 working days. That is a genuine saving against the café, and still dearer per cup than grinding your own beans.
Is the coffee cost calculator free?
Yes — free with no sign-up needed. All calculations run in your browser and no data is stored. Adjust the cups, cost, and days fields to model different scenarios — like what happens if you cut café visits from 5 to 2 days per week.
