What Is This Tool?

This calculator helps homeowners and borrowers assess the financial impact of refinancing a loan. It computes monthly payments for both existing and refinanced loans, estimates monthly savings, break-even timeline, and total interest saved using standard amortization formulas.

How to Use This Tool?

  • Enter your current loan balance, interest rate, and remaining term.
  • Input the refinancing interest rate, term, and any associated refinance costs.
  • Click the calculate button to see monthly payment amounts, monthly savings, break-even period, and total interest savings.
  • Review the results to decide if refinancing could be advantageous based on your financial goals.

Key Features

  • Calculates monthly payments based on loan principal, interest rate, and term.
  • Computes monthly savings comparing original and refinanced payment amounts.
  • Determines the break-even point in months based on upfront refinance costs and monthly savings.
  • Estimates total interest savings over the life of the loan.
  • Uses precise floating-point calculations for accurate amortization results.

Examples

  • A borrower with a $200,000 loan at 6% APR and 25 years remaining refinancing at 4.5% APR for the same term with $3,000 costs sees the monthly payment drop from $1,289.99 to $1,111.72, saving $178.27 monthly.
  • The break-even for these refinance costs is approximately 16.8 months, showing how long it takes for savings to cover upfront expenses.

Common Use Cases

Frequently Asked Questions

What variables are needed to use the refinance calculator?
You need the loan principal, monthly interest rates derived from APR, the number of monthly payments, and any refinance-related costs.

How is the monthly payment calculated?
Monthly payments are computed using the amortization formula M = (P × r × (1+r)^n) / ((1+r)^n - 1), where P is principal, r is monthly interest rate, and n is number of payments.

What does the break-even point tell me?
The break-even point indicates how many months it will take for your monthly savings to cover the upfront refinance costs.

Key Terminology

P
Loan principal amount being refinanced.
r
Monthly interest rate calculated as APR divided by 12.
n
Total number of monthly payments, typically loan term multiplied by 12.
M_old
Monthly payment amount for the existing original loan.
M_new
Monthly payment amount for the refinanced loan.
Refinance Costs
Upfront fees and expenses associated with refinancing the loan.
