Loan Comparison Calculator
What is a Loan Comparison Calculator?
A Loan Comparison Calculator is a financial tool that allows you to compare multiple loans side by side. It helps you evaluate different loan options by calculating and displaying key metrics such as monthly payments, total repayment amounts, and total interest costs for each loan.
The Loan Payment Formula
The core of our loan comparison calculator uses the standard loan payment formula:
\[P = L\frac{r(1+r)^n}{(1+r)^n-1}\]
Where:
- \(P\) = Monthly payment
- \(L\) = Loan amount
- \(r\) = Monthly interest rate (annual rate divided by 12 and 100)
- \(n\) = Total number of payments (loan term in years * 12)
How to Use the Loan Comparison Calculator
- Enter the loan amount for each loan you want to compare
- Input the annual interest rate for each loan
- Specify the loan term in years for each loan
- Click the "Calculate" button to see the comparison results
Example Calculation
Let's compare three loans:
- Loan 1: $10,000 at 13% for 5 years
- Loan 2: $30,000 at 11% for 10 years
- Loan 3: $50,000 at 9% for 20 years
For Loan 1:
- \(r = \frac{13}{12 \times 100} = 0.001083333\)
- \(n = 5 \times 12 = 60\)
- \(P = 10000 \times \frac{0.001083333(1+0.001083333)^{60}}{(1+0.001083333)^{60}-1} = $228.22\)
Similar calculations are performed for Loans 2 and 3.
