2/1 Buydown Calculator

The 2/1 Buydown is a type of mortgage arrangement where the interest rate for the first two years is temporarily reduced. The interest rate is reduced by 2% in the first year and 1% in the second year before returning to the standard rate for the remaining term.

Historical Background

2/1 Buydowns emerged as a strategy to make initial mortgage payments more affordable. It gained popularity as a way for builders and sellers to attract buyers, especially in a high-interest-rate environment.

Calculation Formula

To calculate the monthly payments for each period, the formula used is:

\[ \text{Monthly Payment} = \frac{\text{Principal} \times \frac{\text{Interest Rate}}{12}}{1 - (1 + \frac{\text{Interest Rate}}{12})^{-\text{NPER}}} \]

Where:

• Principal is the loan amount.
• Interest Rate is the annual interest rate for the period.
• NPER is the number of monthly payments for the period.

Example Calculation

For a loan of \$200,000 with a 4% interest rate for the first period (12 months) and a 5% interest rate for the second period (12 months):

First Period Payment:

\[ \frac{\$200,000 \times \frac{0.04}{12}}{1 - (1 + \frac{0.04}{12})^{-12}} \approx \$954.83 \]

Second Period Payment:

\[ \frac{\$200,000 \times \frac{0.05}{12}}{1 - (1 + \frac{0.05}{12})^{-12}} \approx \$1,073.64 \]
