Investment Calculator: Simulate Your Money Growth
Use the investment calculator to project your capital over time and understand how compound interest, monthly contributions, and timeline interact.
Investment Calculator: Simulate Your Money Growth
An investment calculator helps you turn assumptions into realistic projections.
Instead of guessing, you can test scenarios and make clearer decisions.
Use the tool here: Investment Simulator.
Inputs That Matter Most
- Initial capital
- Monthly contribution
- Expected annual return
- Investment horizon (years)
Why This Is Powerful
Compounding is non-linear. Small monthly contributions can become meaningful capital with time.
Time in the market is usually more important than perfect timing.
Example Scenarios
Scenario A
- initial: €5,000
- monthly: €200
- return: 7%
- horizon: 20 years
Scenario B
- initial: €0
- monthly: €350
- return: 7%
- horizon: 30 years
Compare both and you will see how contribution size and horizon interact.
How to Use Simulation Results
- stress-test optimistic assumptions
- check if goals are realistic
- adjust savings rate or timeline
- align risk with horizon
Common Mistakes
- using very optimistic returns
- forgetting inflation impact
- ignoring tax and fee drag
- changing strategy every few months

Conclusion
Simulation does not predict the future, but it improves decision quality.
Use it to build a plan you can execute consistently over many years.
