Simple Interest: Principal × Rate × Time
Compound Interest: Principal × (1 + Rate)Time - Principal
The interest rate calculator uses mathematical formulas. These formulas determine interest costs or earnings. Below are the standard interest calculation methods:
Where: I = Interest, P = Principal, R = Rate (decimal), T = Time (years)
Where: A = Total Amount, P = Principal, R = Rate (decimal), T = Time (years)
Interest = A - P
Our interest rate calculator simplifies complex math. First, it collects your input values. Then, it validates these numbers. Next, it applies the appropriate formula.
For simple interest, it multiplies principal, rate, and time. For compound interest, it calculates exponential growth. Immediately, it displays accurate results.
The calculator handles decimal values precisely. Furthermore, it formats numbers for readability. Importantly, it explains each calculation step. Consequently, you understand your financial picture.
Below are sample calculations using our interest rate calculator:
| Principal | Rate | Time | Type | Interest | Total |
|---|---|---|---|---|---|
| $5,000 | 4% | 3 years | Simple | $600 | $5,600 |
| $5,000 | 4% | 3 years | Compound | $624 | $5,624 |
| $10,000 | 5.5% | 5 years | Simple | $2,750 | $12,750 |
| $10,000 | 5.5% | 5 years | Compound | $3,069 | $13,069 |
| $20,000 | 7.25% | 10 years | Compound | $20,128 | $40,128 |
Simple interest is calculated only on the principal amount. Compound interest includes interest on previously earned interest. Consequently, compound interest grows faster over time. This difference matters most for long-term investments.
Yes, our interest rate calculator supports annual rates. For monthly calculations, divide the annual rate by 12. Then enter time in months instead of years. This adjustment provides monthly interest results.
