See what your investing habit could grow into.
Pop in what you're starting with, what you can add each month, and how long you'll leave it — this shows the maths behind compound growth, not a prediction of what will actually happen.
Your numbers
Changes the symbol shown only — the maths itself isn't converted between currencies.
Global equity index funds have historically returned roughly 5–8% a year after inflation — this is an assumption, not a guarantee.
Balance over time
How your starting amount, contributions, and growth stack up year by year.
This calculator is a general educational tool, not personalised financial advice or a forecast of returns. It assumes a fixed annual return applied monthly, contributions made at the end of each month, and doesn't account for fees, tax, or inflation. Real investments fluctuate and can lose value — capital is at risk.
