Which bank’s loan is this? It’s really weird.
1. In January, first calculate the interest based on segmented interest (quietly charge an extra day of interest, December has 31 days, and the interest rate is calculated based on 360 days), and then subtract the interest amount from the previous year's monthly payment to get the principal. Repayment amount.
2. There is something wrong with the selection of time points in your calculation. It should be calculated to 2021 instead of 2026. In addition, the 5-year deposit earns simple interest rather than compound interest. Rollover after maturity is compound interest.
In this way, 50000*((1+5.225%*5)^2-1)=35445.09
The interest income for 10 years is calculated in this way, and the maturity date is March 2023
The benefit of early repayment is the interest saved, which is 60,000 in total, and the maturity date is January 2021.
It will be clear which one is more cost-effective.
