Frequently asked questions

Complete guide to Investment Growth Calculator

What is an investment growth calculator?

An investment growth calculator projects how your investment grows over time with compound returns. Enter initial amount, regular contributions (optional), expected annual return, and years. It shows the future value and the impact of compounding. Use it for retirement, education, or other long-term goals with realistic return assumptions.

Why compounding matters

Compound growth means you earn returns on your previous returns as well as on principal. Over decades, this can turn modest monthly investments into substantial sums. Small differences in return (e.g. 7% vs 9%) or time (10 vs 20 years) have a large impact on the final amount.
