الأسئلة الشائعة
الدليل الكامل لـ Simple Interest Calculator
What is simple interest?
Simple interest is interest calculated only on the principal amount. It does not compound — interest is not added to the principal for future calculations. That makes it easier to compute and predict than compound interest. Simple interest is common in some short-term loans, certain bonds, and basic savings products.
Simple interest formula
Example: $10,000 at 5% per year for 3 years gives I = 10000 × 0.05 × 3 = $1,500 interest. Total = $11,500. This calculator uses the same formula; enter rate as a percentage (e.g. 5 for 5%).
I = P × R × T
I = interest, P = principal, R = annual interest rate (as a decimal or use %/100), T = time in years. Total amount = P + I.
Simple vs compound interest
- Simple interest: only on principal. Growth is linear.
- Compound interest: on principal plus prior interest. Growth is exponential.
- Over long periods, compound interest yields much more (for savings) or costs much more (for loans).
- Many banks use compound interest for deposits and reducing-balance for loans; some short-term or flat-rate products use simple interest.
