Works out the periodic contribution needed assuming a constant return and monthly compounding. Real returns vary and can be negative. It doesn't account for inflation or taxes. Not financial advice.
This savings goal calculator works out how much you need to save each month to reach your goal within a given timeframe.
From your goal to a monthly contribution
Instead of asking “how much will I have in X years?”, this calculator answers the reverse question: how much should I contribute each month to reach a specific amount. It factors in your initial savings and the effect of compound interest.
Example: reaching €30,000 in 10 years
With €3,000 in initial savings and a 5% annual return, reaching €30,000 in 10 years takes a monthly contribution of about €161.38. Of that €30,000, roughly €7,635 would be interest.

FAQ
What does this tool calculate?
The amount you need to contribute each month to reach a savings goal within your chosen timeframe, factoring in your initial savings and the expected return on your investments.
Why do I need to contribute less than it seems?
Because your contributions earn interest, and that interest earns more interest (compound interest). The higher the return and the longer the timeframe, the less you need to contribute out of pocket to reach the goal.
What return rate should I use?
A conservative estimate that matches where you're investing. Cash savings barely earn anything; a diversified long-term portfolio has historically averaged around 5-7% a year, though it varies and can be negative.
Does it account for inflation?
No — it works in nominal terms. If you want to reason in terms of purchasing power, use a return rate that already has expected inflation subtracted from it.
