How will it be calculated after partial early repayment? Analysis of hot topics across the Internet
Recently, the calculation method of prepayment of mortgage loan has become a hot topic. Many home buyers hope to reduce interest expenses through early repayment. This article will combine the hot content on the Internet in the past 10 days, analyze in detail the calculation rules after some early repayments, and provide structured data for reference.
1. Basic rules for partial early repayment

Partial prepayment refers to the borrower's one-time repayment of part of the principal within the repayment period. Its core impacts include:
| Project | Impact statement |
|---|---|
| remaining principal | Direct reduction, subsequent interest is calculated based on the new principal |
| repayment period | Option to shorten term or reduce monthly payment |
| total interest expense | Significantly reduced due to principal reduction |
2. Comparison of two mainstream computing methods
Depending on bank policies, there are usually two ways to deal with partial early repayment:
| way | Features | Applicable people |
|---|---|---|
| The term remains the same and the monthly payment is reduced | Lower monthly repayment pressure and less total interest savings | Cash flow tight |
| Monthly payment remains unchanged, term shortened | Close your loan faster and save more on total interest | Stable income earner |
3. Specific calculation case demonstration
Taking a loan of 1 million yuan with an interest rate of 4.9% and equal principal and interest for 30 years as an example, an early repayment of 200,000 yuan in the fifth year is as follows:
| indicator | original plan | Reduced monthly payment plan | Reduced term plan |
|---|---|---|---|
| remaining principal | 924,000 | 724,000 | 724,000 |
| Remaining term | 25 years | 25 years | 18 years and 3 months |
| Monthly payment amount | 5307 yuan | 4158 yuan | 5307 yuan |
| Save interest | - | 192,000 yuan | 286,000 yuan |
