3-2-1 Buydown Calculator
A 3-2-1 mortgage buydown can significantly reduce your monthly mortgage payments during the first three years of homeownership, helping make a new home more affordable while providing additional financial flexibility during the transition into homeownership.
Our 3-2-1 Buydown Calculator helps you estimate payment savings, compare financing scenarios, and understand how a temporary rate reduction may affect your mortgage over time.
What Is a 3-2-1 Buydown?
A 3-2-1 buydown is a temporary mortgage financing strategy that reduces the interest rate by:
- 3% during Year 1
- 2% during Year 2
- 1% during Year 3
- Returns to the full note rate beginning in Year 4
For example:
- Note Rate: 7.00%
- Year 1 Rate: 4.00%
- Year 2 Rate: 5.00%
- Year 3 Rate: 6.00%
- Year 4 and Beyond: 7.00%
The cost of the temporary rate reduction is typically funded through a buydown account established at closing. Depending on the transaction, funds may be contributed by the seller, builder, lender, or another eligible party.

How a 3-2-1 Buydown Works
Year 1
The interest rate is reduced by 3%, resulting in the largest temporary payment savings.
Year 2
The interest rate is reduced by 2%, providing continued affordability benefits.
Year 3
The interest rate is reduced by 1%, creating a gradual transition toward the permanent payment amount.
Year 4 and Beyond
The mortgage returns to the original note rate established at closing and remains fixed according to the loan terms. Because the payment increases gradually, borrowers can plan for future housing expenses while benefiting from lower early payments.
Benefits of a 3-2-1 Buydown
Maximum Initial Savings
The first year typically provides the largest payment reduction, offering meaningful short-term financial relief.
Gradual Payment Adjustment
Rather than experiencing a single large increase, payments rise gradually over a three-year period.
Improved Affordability
Some borrowers may find that lower initial payments make homeownership more accessible during periods of higher mortgage rates.
Seller and Builder Incentives
In certain market conditions, sellers and builders may offer buydown incentives to help qualified buyers reduce monthly housing costs.
Important Considerations
Before choosing a 3-2-1 buydown, evaluate:
Future Payment Obligations
You should be comfortable making the full note-rate payment once the temporary buydown expires.
Long-Term Financial Goals
Budgeting should be based on the permanent mortgage payment rather than the temporary discounted payment.
Employment and Income Expectations
Some borrowers use temporary buydowns when they expect future income growth or changing financial circumstances.
Alternative Financing Options
Other mortgage solutions may include:
- Permanent rate buydowns
- Adjustable-rate mortgages (ARMs)
- Different loan terms
- Larger down payments
- Alternative loan programs
