Compound interest formula
A = P × (1 + r/n)n×t, and compound interest = A − P.
Example: ₹1,00,000 at 8% compounded yearly for 10 years becomes ₹2,15,892. Simple interest would give only ₹1,80,000.
Frequently asked questions
What is the difference between simple and compound interest?
Simple interest is calculated only on the principal. Compound interest is calculated on the principal plus interest already earned, so it grows faster.
