Loan Calculator with Interest
A loan calculator with interest is a handy tool to determine your periodic loan payments. It helps you plan your finances by calculating how much you’ll pay monthly for a loan based on the interest rate, loan term, and loan amount.
Formula
The formula for calculating loan payments is:
P = (i * A) / [1 – (1 + i)^-N]
Where:
- P is the periodic payment.
- A is the loan amount or principal.
- i is the periodic interest rate (annual rate divided by payments per year).
- N is the total number of payments.
How to Use
- Enter the loan amount (A) in your desired currency.
- Input the annual interest rate (in percentage).
- Specify the loan term in years.
- Enter the number of payments per year (typically 12 for monthly payments).
- Click “Calculate” to see the periodic payment (P).
Example
Suppose you take a loan of $10,000 at an annual interest rate of 5% for a term of 5 years with monthly payments.
- Loan Amount (A): $10,000
- Annual Interest Rate: 5%
- Loan Term: 5 years
- Payments per Year: 12
Using the formula:
i = 5 / (100 * 12) = 0.004167
N = 5 * 12 = 60
P = (0.004167 * 10000) / [1 – (1 + 0.004167)^-60] ≈ $188.71
The monthly payment would be approximately $188.71.
