SI: 1,000 at 1% for 1 Years
Simple interest on 1,000 at 1% per year for 1 years: 10.00. Total amount: 1,010.00. Free SI calculator.
SI = P x R x T / 100 = 1,000 x 1 x 1 / 100 = 10.00. Total = 1,010.00.
How This Was Calculated
Simple Interest = (P x R x T) / 100
Where P = principal, R = annual rate, T = time in years. Total Amount = P + SI
Unlike compound interest, simple interest never earns interest on interest — growth is linear, so each year adds exactly P x R / 100.
Frequently Asked Questions
What is simple interest?
Simple interest is calculated only on the original principal — interest does not compound. Each period earns exactly the same amount: Principal x Rate x Time / 100.
What is the difference between simple and compound interest?
Simple interest grows linearly; compound interest grows exponentially because each period earns interest on previous interest. Over 10 years at 10%, 10,000 becomes 20,000 with simple interest but 25,937 with annual compounding.
Where is simple interest used in real life?
Short-term loans, some car loans, treasury bills, and certain bonds. Most savings accounts and FDs use compound interest instead.
How do I calculate simple interest per month?
Use T in years as months / 12. For 6 months at 12% on 10,000: 10,000 x 12 x 0.5 / 100 = 600.
Is simple interest better for borrowers?
Yes — borrowers pay less with simple interest than compound interest at the same rate and term, which is why lenders usually prefer compound structures.
