Money Saving Tools

These money saving tools are simple calculators that run in your browser. There is no sign-up, and nothing you type is sent to us. Use them to check whether a deal is a real saving, to work out the yearly cost of a subscription and to find the cancel-by date for a free trial.

Saving calculator: the first of our money saving tools

Enter the normal price and the offer price to see how much you save and the percentage off. It is a quick way to test a sale. If a “50% off” label does not match the numbers, you will see it straight away. For more on judging a sale, read our guide on how to spot a fake discount.

Subscription calculator: money saving tools for regular bills

Pick how often you pay, enter the price and see the yearly cost and the monthly average. A £9.99 monthly plan costs £119.88 a year, and a weekly plan costs far more than it looks. Our guide to the yearly subscription cost shows how to audit everything you pay for.

Free trial calculator: when must I cancel?

Enter the start date and the number of days. You will get the end date, a safe cancel-by date a day earlier and a suggested reminder date two days before. Read how to cancel a free trial without being charged for the full steps.

Unit price calculator: which pack is cheaper?

Packs come in different sizes, so the shelf price tells you little. Enter the price and size of two packs and pick the unit, and this works out the price per kilogram, litre or item. Our guide to the unit price explains why it matters.

Stacked discount calculator: what is the real total?

A percentage off, then a voucher, then a code does not add up the way the labels suggest. Enter the starting price and each step to see what you would really pay and the overall percentage saved.

How to use these money saving tools well

1. Use real prices from the shop’s own page, including delivery if it is charged.
2. Compare like with like: the same item, the same size and the same condition.
3. Round up costs, not down, when you are deciding whether you can afford something.
4. Keep a note of the date a trial starts, and set the reminder straight away.

Money saving tools: why we built them

A calculator turns a feeling into a number. Most people compare prices by eye, and shops know it. Working out the real saving, the real yearly cost or the real cancel date takes seconds and often changes your mind. That is the point of these tools, and they are free for everyone.

Questions about our money saving tools

Do the tools store what I type?

No. They run in your browser and nothing you enter is sent to us.

Are the results exact?

The sums are exact. What you enter decides whether the answer is useful, so check your prices and dates. For trials, check the provider’s own cut-off time too.

Can I share a result?

Yes. The tools can be filled in from the address, so you can share a link that already has the numbers in it.

Where to get more money advice

Tools help with the sums, but they do not replace advice. MoneyHelper offers free, independent guidance on budgeting, bills and everyday money, and Citizens Advice can help if you think a shop has treated you unfairly. We also build new money saving tools when readers ask for them, so tell us what would help. Each one is free, quick to use and designed to give you a clear answer in a few seconds, so you can decide with confidence.
