Formula used
Investment tools use compound growth. SIP pages convert annual return to a monthly rate, goal pages estimate the monthly saving needed, and inflation pages project future value using Amount x (1 + inflation rate)^years.
Result explained
Focus on invested amount, estimated gain and inflation-adjusted value together. A high future value is less useful if the real purchasing power is lower than your goal.
Example
Try your current monthly saving first, then increase the return or step-up rate only within realistic limits. Small early changes usually make a larger difference than aggressive assumptions at the end.
Assumptions used
- Returns are assumed, not guaranteed.
- Taxes, exit loads and product-specific charges may reduce actual returns.
- Use conservative return and inflation assumptions for important goals.
- Results are rounded for readability and should be verified before major money decisions.

Frequently Asked Questions
What is compound interest?
Compound interest is interest earned on both principal and previously earned interest. It's often called "interest on interest" and results in exponential growth over time.
What does compounding frequency mean?
Compounding frequency is how often interest is calculated and added to principal. Higher frequency (like daily) results in more interest earned compared to lower frequency (like annually).
How is compound interest different from simple interest?
