Simple Interest Calculator – Calculate SI Amount Instantly
Calculate simple interest, total amount and interest earned using the standard SI formula. Useful for short-term loans, savings bonds and basic financial planning.
SI = (P × R × T) / 100, where P = Principal amount, R = Rate of interest per annum, T = Time in years. Total Amount = P + SI. Example: ₹1,00,000 at 7% for 3 years: SI = 1,00,000 × 7 × 3 / 100 = ₹21,000. Total = ₹1,21,000.
What is the difference between simple and compound interest?▼
In Simple Interest, interest is always calculated on the original principal only. In Compound Interest, interest is calculated on principal + accumulated interest. For same amount/rate/time: Compound Interest always gives more than Simple Interest. FDs, SIPs, and most investments use compound interest. Simple interest is used for short-term loans.
