| Calculation Type | Formula | Example |
|---|---|---|
| Simple Interest | Interest = Principal × Rate × Time | $1,000 at 5% for 3 years = $150 |
| Compound Interest | Future Value = Principal × (1 + Rate)^Time | $1,000 at 5% for 3 years = $1,157.63 |
| Loan Payment | Payment = (Principal × Rate × (1 + Rate)^Term) / ((1 + Rate)^Term - 1) | $200,000 at 4% for 30 years = $1,073.64/month |
Formulas Used
The calculator uses standard financial formulas to ensure accurate results. Here are the key formulas:
Simple Interest
Interest = Principal × Rate × Time
Where:
- Principal = Initial amount of money
- Rate = Annual interest rate (in decimal)
- Time = Time in years
Compound Interest
Future Value = Principal × (1 + Rate)^Time
Where:
- Principal = Initial amount of money
- Rate = Annual interest rate (in decimal)
- Time = Time in years
Loan Payment
Payment = (Principal × Rate × (1 + Rate)^Term) / ((1 + Rate)^Term - 1)
Where:
- Principal = Loan amount
- Rate = Monthly interest rate (in decimal)
- Term = Loan term in months
Worked Examples
Here are some worked examples to illustrate how the calculator works:
Example 1: Simple Interest Calculation
Suppose you deposit $1,000 in a savings account with an annual interest rate of 5%. How much interest will you earn in 3 years?
Using the formula:
Interest = $1,000 × 0.05 × 3 = $150
So, you will earn $150 in interest over 3 years.
Example 2: Compound Interest Calculation
If you invest $1,000 at an annual interest rate of 5% with compound interest, how much will you have after 3 years?
Using the formula:
Future Value = $1,000 × (1 + 0.05)^3 = $1,157.63
After 3 years, your investment will grow to $1,157.63.
Example 3: Loan Payment Calculation
You take out a $200,000 mortgage at an annual interest rate of 4% for 30 years. What will your monthly payment be?
First, convert the annual rate to a monthly rate: 4% ÷ 12 = 0.333% or 0.00333 in decimal.
Then, use the loan payment formula:
Payment = ($200,000 × 0.00333 × (1 + 0.00333)^360) / ((1 + 0.00333)^360 - 1) = $1,073.64
Your monthly payment will be $1,073.64.
