Buying a home often comes with high monthly mortgage payments, which can be stressful in the first few years. A 2/1 buydown mortgage allows homeowners to pay a reduced interest rate for the first two years, making initial payments more affordable. The 2/1 Buydown Calculator helps you estimate your monthly payments, savings, and overall financial impact.

What is a 2/1 Buydown Mortgage?
A 2/1 buydown is a type of mortgage where:
- Year 1 – Interest rate is reduced by 2%.
- Year 2 – Interest rate is reduced by 1%.
- Year 3 onward – Mortgage returns to the original note rate.
This structure allows new homeowners to ease into their mortgage payments and save money during the initial years.
Formula for 2/1 Buydown Calculation
The calculation involves determining monthly payments based on adjusted interest rates for the first two years:
Monthly Payment = (Loan Amount × Monthly Interest Rate) ÷ (1 − (1 + Monthly Interest Rate)^−Number of Payments)
Where:
- Monthly Interest Rate = Annual Rate ÷ 12
- Number of Payments = Loan term in months
Step 1: Calculate Year 1 payment at (Note Rate − 2%)
Step 2: Calculate Year 2 payment at (Note Rate − 1%)
Step 3: Calculate Year 3 onward payment at the full Note Rate
Example Calculation
Scenario:
- Loan Amount: $300,000
- Note Rate: 6%
- Loan Term: 30 years
Year 1:
Adjusted Rate = 6% − 2% = 4%
Monthly Payment ≈ $1,432
Year 2:
Adjusted Rate = 6% − 1% = 5%
Monthly Payment ≈ $1,610
Year 3+:
Full Rate = 6%
Monthly Payment ≈ $1,799
Savings:
- Year 1 Savings = $1,799 − $1,432 = $367/month
- Year 2 Savings = $1,799 − $1,610 = $189/month
