Buydown Cost
What Is a Mortgage Rate Buydown?
A mortgage rate buydown is a financial strategy where a borrower pays an upfront fee to reduce the interest rate on their mortgage. This lower rate can result in smaller monthly payments, making homeownership more affordable in the initial years of the loan.
Buydowns are commonly offered in two ways:
- Permanent Buydown – The interest rate is reduced for the entire loan term.
- Temporary Buydown – The interest rate is reduced for a set period, often the first 1–3 years.
The cost of the buydown is typically expressed as a percentage of the loan amount.
How the Mortgage Rate Buydown Calculator Works
The calculator simplifies the process by using the formula:BuydownCost=LoanAmount×(BuydownRate÷100)
This straightforward approach helps you:
- Estimate upfront costs to reduce interest rates
- Compare different buydown options
- Evaluate if paying upfront is worth the monthly savings
Unlike manual calculations, the calculator instantly provides accurate results, helping you plan effectively.
How to Use the Mortgage Rate Buydown Calculator

Calculation:BuydownCost=300,000×(1÷100)=3,000
This means you would pay $3,000 upfront to reduce your mortgage rate by 1%, potentially lowering monthly payments and interest over the life of the loan.
