FAQ

Compound interest is growth on both your principal and previously earned interest. Over long periods, compounding can accelerate portfolio growth, especially when you continue adding regular contributions.

The calculator starts with your initial investment, applies the selected annual return using your chosen compounding frequency, and then adds recurring contributions based on your selected contribution period (monthly, quarterly, or yearly). It shows summary metrics, a growth chart, and a yearly breakdown table.

Contributions are the money you invest yourself (initial amount plus recurring deposits). Interest earned is the growth generated by your portfolio over time. The final balance is the sum of both.

In general, more frequent compounding slightly increases returns for the same nominal annual rate. The impact is usually modest, but it becomes more noticeable across longer time horizons.

No. It is a planning tool based on fixed assumptions. Real market returns vary over time, so actual results can be higher or lower than the projections shown in the calculator.
