How to Calculate Compound Interest?
You can use the compound interest formula to manually compute the interest. For instance, say you have invested Rs. 1,00,000 at an annual interest rate of 5%, compounded quarterly, for 3 years. Plugging these details into the formula, we have the following.
Compound interest:
= P [(1 + r/n)nt — 1]
= Rs. 1,00,000 [(1 + 0.05/4)4 x 3 — 1]
= Rs. 1,00,000 [(1 + 0.0125)12 — 1]
= Rs. 1,00,000 [1.1608 — 1]
= Rs. 1,00,000 x 0.1608
= Rs. 16,080 (approximately)
