A gambling spend calculator does one blunt job: it takes the amount you lose in a normal week and shows what that habit costs over years. £20 a week doesn’t sound like much. It’s £1,040 a year and £10,400 over ten. This one is free, keeps nothing you type, and lets you pick your own currency in the corner.

Gambling spend calculator: why the weekly figure lies

Nobody thinks about gambling in years. You think about tonight, or this weekend, or the £10 you put on before the match. Small amounts feel like small decisions, and each one on its own is.

The trouble is that they repeat. Here’s the same £20 a week, stretched out:

Period £5 a week £20 a week £50 a week
1 year £260 £1,040 £2,600
5 years £1,300 £5,200 £13,000
10 years £2,600 £10,400 £26,000
20 years £5,200 £20,800 £52,000

£50 a week for ten years is a house deposit in a lot of towns. That isn’t a lecture, it’s arithmetic. If you’re fine with the number, fine. Most people just never see it written down.

What to put in

Use your net loss: money in minus money out. Deposit £30, cash out £10, and that week cost you £20. Winning weeks count too, which is why a month or a few months of bank statements give a fairer figure than guessing from memory. Memory is generous with wins and forgetful with losses. Everybody’s is.

If you play on several sites or apps, add them up. Scratchcards and lottery tickets count. So does the fiver in the office sweepstake, if you want the honest total.

The pay comparison

Open “Compare with your income” and add your take-home pay. You’ll see what share of each month goes on gambling. With £1,800 a month take-home, £20 a week is about 4.8%. Add an hourly rate after tax and it also shows how many hours of work the yearly loss costs: at £11 an hour, £1,040 is roughly 95 hours, or about 13 working days.

That last number tends to land harder than the cash. Two and a half weeks of work a year, gone, for a habit you might not even enjoy much any more.

If the number surprises you

You don’t have to quit anything today to do something useful with it. A few things that actually help:

  • Pick a monthly figure you’d be fine losing in full and set it as a deposit limit. The deposit limit calculator works one out from your income and bills.
  • Track it for a month with the bet tracker. Real numbers beat estimates.
  • See what the games cost per hour with the expected loss calculator. Faster games eat budgets faster.

And if the total worries you, the services in the box below are free and you can talk to them without giving your name.

Frequently asked questions

How do I work out how much I spend on gambling?

Add up deposits and subtract withdrawals over a few months, then divide by the number of weeks. That is your net weekly spend. Bank statements are more reliable than memory.

How much is £20 a week over a year?

£1,040 a year, £5,200 over five years and £10,400 over ten.

Should I count winnings?

Yes. Use net loss: money in minus money out. A week where you deposit £50 and withdraw £40 cost you £10.

Is any of my data saved?

No. The numbers stay in your browser and are not sent anywhere.
