FV = P × (1 + i)ⁿ + C × [((1 + i)ⁿ − 1) ÷ i]
₹1,00,000 starting balance plus ₹5,000 every month for 15 years at 10%.
Final value approximately ₹25,17,744 — growth of ₹15,17,744 on ₹10,00,000 deposited.
Over the same 10 years, ₹1,00,000 at 10% simple interest returns ₹2,00,000 while compound returns ₹2,59,374. The ₹59,374 gap is interest earned on interest, and it widens non-linearly — doubling the period far more than doubles the gap.
Frequently asked questions about calculation formulas, privacy, and usage.
More frequent compounding (daily/monthly vs annual) results in slightly higher effective returns at the same nominal rate, since interest itself starts earning interest sooner.
Simple interest is calculated only on the original principal throughout the term. Compound interest is calculated on the principal plus previously accumulated interest, causing growth to accelerate over time.
Adding regular contributions on top of a lump sum can significantly increase the final corpus compared to a one-time deposit alone, especially over long durations, since each contribution has its own compounding runway.
