About Snowpound
Snowpound is a free compound interest calculator made by Nordic Coders. What it does, how it works out its figures, and how it is paid for.
What Snowpound is
Snowpound is a free compound interest calculator. You enter a starting amount, a regular contribution, a yearly return and a number of years, and it shows how the balance grows — as a chart, as totals, and year by year, with what you paid in kept apart from what the interest added.
It is available in 17 languages, each with its own currency and number format. Alongside the calculator, the guides explain the things that change a real result: fees, inflation, the way interest rates are quoted, and debt.
Who makes it
Snowpound is made and run by Nordic Coders. Questions, corrections and suggestions are welcome — see the contact page.
How the figures are worked out
The calculator uses the standard compound interest formula, with contributions added on top. Monthly contributions are treated as paid at the start of each month and yearly ones at the end of the year. The calculator page describes the method in full under "How this calculator works".
The worked examples in the guides are produced by the same code as the calculator, from the same default amounts, so an example repeated in the calculator gives the same result.
Every result assumes the same return in every year and leaves out tax, inflation and fees. That makes the figures useful for comparing scenarios, not for predicting a balance.
What it is not
Snowpound is not financial advice. It does not recommend, sell or compare financial products, and nothing on the site is a suggestion about what you should do with your money. For decisions about your own finances, talk to a qualified adviser.
How it is paid for
The calculator is free to use, with no account and no sign-up. Pages may show advertising served by Google, which is what pays for the site. Saved scenarios stay in your own browser and are never sent to us. The privacy policy explains exactly what is stored and what is shared.
