Calculate what your investment will be worth in the future with compound interest.
| Initial Investment | — |
| Additional Contributions | — |
| Total Interest Earned | — |
FV = PV × (1 + r/n)^(nt) where PV = present value, r = annual rate, n = compounding periods/year, t = years. For example, ₹1 lakh at 10% for 10 years (quarterly) = ₹2,68,506.
Divide 72 by the interest rate to find how long it takes to double your money. At 10% per year: 72 ÷ 10 = 7.2 years to double. At 12%: 72 ÷ 12 = 6 years.
