This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the calculation method of home purchase loans, and provide structured data to help you better plan your home purchase budget.
1. Basic elements of mortgage loan calculation
The calculation of a home loan mainly involves the following key elements: loan amount, loan term, interest rate and repayment method. Below is a detailed description of these elements:
| elements | Description |
|---|---|
| loan amount | The total purchase price minus the down payment is usually 70%-80% of the house price. |
| loan term | Common loan terms are 10, 20 or 30 years. The longer the term, the lower the monthly payment, but the higher the total interest. |
| interest rate | It is divided into fixed interest rate and floating interest rate. The current commercial loan interest rate is about 4.1%-4.9%, and the provident fund loan interest rate is 3.1%-3.25%. |
| Repayment method | There are two methods: equal principal and interest and equal principal. The former has a fixed monthly payment, while the latter has a monthly payment that decreases month by month. |
2. Mortgage calculation formula
The formula for calculating a mortgage differs depending on the repayment method. Here’s how two common repayment options are calculated:
| Repayment method | Calculation formula |
|---|---|
| Equal principal and interest | Monthly payment = [Loan principal × monthly interest rate × (1 + monthly interest rate)^number of repayment months] ÷ [(1 + monthly interest rate)^number of repayment months - 1] |
| Equal amount of principal | Monthly payment = (Loan principal ÷ Number of repayment months) + (Loan principal - Accumulated amount of principal repaid) × Monthly interest rate |
3. Mortgage calculation example
Suppose you buy a house with a total price of 2 million yuan, a down payment of 30% (600,000 yuan), a loan of 1.4 million yuan, a term of 20 years, and an interest rate of 4.5%. Here are the calculations for the two repayment options:
| Repayment method | Monthly payment (first month) | total interest |
|---|---|---|
| Equal principal and interest | 8,849 yuan | About 724,000 yuan |
| Equal amount of principal | 11,083 yuan | About 633,000 yuan |
