Returns are assumed constant and gross of tax. Real markets are lumpy, so treat this as a trend line rather than a forecast.
How to read the result
Compounding is unremarkable for the first few years and then does almost all of the work at the end. Most people underestimate the back half badly.
Set a starting balance, a monthly contribution and a rate, and the projection below splits the final number into what you put in versus what the growth added.
This page is set to Denmark and prints DKK. Starts at a 2.5% deposit return. Every figure is a starting point you should overwrite with your own.

Questions people ask
- Monthly or annual compounding?
- This model compounds monthly and adds your contribution at the end of each month, which matches how most brokerage and savings accounts behave.
- What rate should someone in Denmark use?
- For a broad global equity index, 6–8% before inflation is a common planning assumption anywhere. For cash, use your local deposit rate — around 2.5% in Denmark at the moment.
- Does this account for tax?
- No. Tax-sheltered accounts exist in most countries and change the outcome materially, so compare the gross figure here against your own account rules.
