Goal Calculator
Working toward a target amount? This tool turns the interest formulas around: instead of asking “how much will I have”, it asks“how long until I get there?” — solved directly from SI = P·R·T/100 or the logarithmic compounding formula.
How Long Will It Take to Reach Your Goal?
Approximately 5y 3m
₹1,00,000 at 8% compound (annually) interest takes about 5y 3m to reach ₹1,50,000.
This is a mathematical estimate computed from the stated formula — not a guaranteed investment projection. Real products may round crediting dates differently, and taxes or fees can change the outcome.
How the math works
- Simple interest: T = (target ÷ P − 1) ÷ r
- Compound (periodic): T = ln(target ÷ P) ÷ (n × ln(1 + r/n))
- Continuous compounding: T = ln(target ÷ P) ÷ r
- With 0% rate, the target can never be reached by interest alone — the tool tells you so.
The result is a mathematical estimate under the selected assumptions, not a guaranteed investment projection.
