2. How to calculate mortgage interest
The calculation of mortgage interest is mainly divided into two methods: equal principal and interest and equal principal. Here's a comparison of the two:
| Calculation method | Features | Applicable people |
|---|---|---|
| Equal principal and interest | The monthly repayment amount is fixed, and the interest proportion decreases month by month. | Homebuyers with stable income |
| Equal amount of principal | The monthly principal repayment is fixed and the interest decreases every month. | Homebuyers with strong early repayment ability |
1. Calculation formula for equal amounts of principal and interest
Monthly repayment = [Loan principal × monthly interest rate × (1+monthly interest rate)^number of repayment months] ÷ [(1+monthly interest rate)^number of repayment months - 1]
2. Calculation formula for equal amounts of principal
Monthly repayment = (loan principal ÷ number of repayment months) + (remaining principal × monthly interest rate)
3. Actual case demonstration
Assume that the loan amount is 1 million yuan, the term is 30 years (360 months), and the interest rate is 5%. The following is a comparison of the first month repayment of the two methods:
| Calculation method | First month’s repayment amount | total interest |
|---|---|---|
| Equal principal and interest | 5,368 yuan | 932,686 yuan |
| Equal amount of principal | 6,944 yuan | 752,083 yuan |
