Formula Used
The calculator uses the simple interest formula:
Simple Interest Formula
Interest = Principal × Rate × Time
Final Balance = Principal + Interest
Where:
- Principal = Initial amount of money
- Rate = Interest rate (0.15 or 15%)
- Time = Number of years
This formula assumes the interest rate is fixed and does not compound over time. For compound interest calculations, different formulas would apply.
Worked Example
Let's say you deposit $1,000 in a bank account with a 0.15 (15%) interest rate for 3 years.
Example Calculation
Interest = $1,000 × 0.15 × 3 = $450
Final Balance = $1,000 + $450 = $1,450
After 3 years, you would have earned $450 in interest and your account balance would be $1,450.
Frequently Asked Questions
What is a 0.15 interest rate?
A 0.15 interest rate means the bank pays 15% of your principal amount as interest each year. For example, on $1,000, you'd earn $15 per year.
Is this simple or compound interest?
This calculator uses simple interest, which means interest is calculated only on the original principal amount. Compound interest would earn interest on both the principal and previously earned interest.
How often is the interest paid?
The calculator assumes annual interest payments. Some banks may pay interest more frequently (monthly, quarterly), which would affect the total amount earned.
