How Can I Calculate Closing Costs


When you’re in the process of buying a home, understanding the costs involved is crucial. Closing costs are a significant part of the expenses you’ll face. These costs encompass various fees and charges associated with finalizing a real estate transaction. To help you estimate your closing costs, we’ve created a Closing Costs Calculator, which allows you to determine your monthly mortgage payment and the overall cost of your loan.


To use the Closing Costs Calculator effectively, it’s essential to comprehend the formula it employs:

  1. Calculate the loan principal: The principal is determined by subtracting the down payment (expressed as a percentage) from the home’s purchase price. This represents the amount you will be borrowing.
  2. Determine the monthly interest rate: The annual interest rate is converted into a monthly rate by dividing it by 100 and then by 12, as there are 12 months in a year.
  3. Find the number of payments: Multiply the loan term (in years) by 12 months to get the total number of payments you’ll make over the life of the loan.
  4. Use the formula for monthly mortgage payments: Monthly mortgage payments are calculated using the formula Mortgage = (Principal * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate) ^ -Number of Payments).
  5. Calculate the total cost of the loan: The total cost of the loan is determined by multiplying the monthly mortgage payment by the total number of payments.
