Why use a calculator?

Money decisions feel abstract until you see the number. A £150 monthly investment doesn't sound like much, and a daily coffee doesn't feel like a big expense. Put a timeline on them and the picture changes. These calculators make that visible in seconds, so you can make decisions on purpose rather than on autopilot.

Questions people ask

Are these calculators free?

Yes. They are free to use, need no sign-up, and the numbers you enter stay in your browser.

Are the results accurate?

They are illustrations based on a steady growth rate. Real investment returns go up and down, so treat the results as a guide to what is possible, not a promise.

Can I share my results?

Yes. Each calculator saves your settings in the web address, so you can copy the link and send your exact numbers to someone else.
