The calculator uses the advanced loan payment formula:
Where:
Explanation: The formula calculates the fixed monthly payment needed to pay off a loan with interest over the specified term, accounting for the time value of money.
Details: Accurate loan payment calculation is crucial for financial planning, budgeting, and comparing different loan options. It helps borrowers understand their repayment obligations and make informed borrowing decisions.
Tips: Enter the principal amount in dollars, annual interest rate as a decimal (e.g., 0.05 for 5%), and the loan term in months. All values must be positive numbers.
Q1: Why divide the annual rate by 12?
A: Dividing by 12 converts the annual interest rate to a monthly rate, as payments are typically made monthly.
Q2: What if I have a different payment frequency?
A: The formula would need adjustment for different payment frequencies (e.g., quarterly or bi-weekly payments).
Q3: Does this formula account for additional fees?
A: No, this formula calculates only the principal and interest portion. Additional fees like origination fees or insurance would need to be added separately.
Q4: What's the difference between this and simple interest?
A: This formula calculates amortized payments where each payment covers both interest and principal, unlike simple interest which only calculates interest on the original principal.
Q5: Can this formula be used for mortgage calculations?
A: Yes, this is the standard formula used for calculating fixed-rate mortgage payments.
