Refinance Summary


What Is Refinancing?

Refinancing is the process of replacing an existing loan with a new one, typically to secure a lower interest rate, change the loan term, or consolidate debt. It’s a common strategy for homeowners to reduce monthly payments, save money on interest, or access cash through a cash-out refinance.

Key Benefits of Refinancing

  • Lower Interest Rates: Reduce the amount of interest paid over time.
  • Shorter Loan Term: Pay off your mortgage faster with higher monthly payments.
  • Lower Monthly Payments: Spread your payments over a longer term to improve cash flow.
  • Cash-Out Option: Access home equity for renovations, debt consolidation, or investments.

How the Refinance Cost Calculator Works

This calculator uses a standard amortization formula to estimate:

  1. Monthly Payment: Based on loan amount, interest rate, and loan term.
  2. Total Interest Paid: Total interest accumulated over the life of the loan.
  3. Total Payment: Total amount including principal, interest, and closing costs.

Formula for Monthly Payment:M=P×r(1+r)n(1+r)n1M = P \times \frac{r(1+r)^n}{(1+r)^n-1}M=P×(1+r)n−1r(1+r)n​

Where:

  • MMM = monthly payment
  • PPP = loan amount
  • rrr = monthly interest rate (annual rate ÷ 12)
  • nnn = total number of payments (years × 12)

The calculator also adds closing costs to your total payment for a complete overview of refinance expenses.

Example Calculation

Suppose you have the following:

  • Loan Amount: $200,000
  • Interest Rate: 5%
  • Loan Term: 30 years
  • Closing Costs: $3,000

Monthly Payment Calculation:r=0.05/12=0.004167r = 0.05 / 12 = 0.004167r=0.05/12=0.004167 n=30×12=360n = 30 × 12 = 360n=30×12=360 M=200,000×0.004167(1+0.004167)360(1+0.004167)36011073.64M = 200,000 × \frac{0.004167(1+0.004167)^{360}}{(1+0.004167)^{360}-1} ≈ 1073.64M=200,000×(1+0.004167)360−10.004167(1+0.004167)360​≈1073.64

Total Interest: $1073.64 × 360 − 200,000 ≈ $186,510.40
Total Payment: $200,000 + $186,510.40 + $3,000 = $389,510.40

This quick calculation helps you decide if refinancing is worth the cost.
