The Bankrate Loan Calculator helps you determine your monthly loan payments and total interest using standard financial formulas. It provides a clear breakdown of repayment obligations.
The calculator uses two main formulas:
Where:
Explanation: The first formula calculates total interest, while the second determines the fixed monthly payment needed to pay off the loan.
Details: Understanding your repayment obligations helps with financial planning, comparing loan offers, and budgeting for monthly expenses.
Tips: Enter principal in USD, interest rate as decimal (e.g., 0.05 for 5%), term in years, and number of payments. Select whether your rate is annual or monthly.
Q1: Should I use annual or monthly rate?
A: Most loans quote annual rates, but check your loan terms. The calculator will convert annual to monthly automatically.
Q2: How does payment frequency affect results?
A: This calculator assumes monthly payments. For biweekly or other frequencies, adjustments would be needed.
Q3: Why is my actual payment slightly different?
A: Lenders may include fees or use slightly different rounding methods. This provides an estimate.
Q4: Can I use this for mortgage calculations?
A: Yes, though mortgages often have additional factors like PMI or escrow that aren't accounted for here.
Q5: How can I reduce total interest paid?
A: Make larger payments, choose shorter terms, or secure lower interest rates to reduce total interest.
