Frequently asked questions
What does the calculator actually show?
Year by year, how your money grows — and how much of the total came from your pocket versus from interest.
What is compound interest, in one line?
Interest that also earns interest: each year’s gains join the base for the next, which is why growth speeds up over time.
Can I include monthly contributions?
Yes. Set what you add regularly and the chart shows the effect of contributing constantly, which is where the magic really is.
Is my financial data stored anywhere?
No. Everything is computed in your browser and nothing is saved or sent.
