Shown is a simple equal principal loan monthly calculation, the first line is the total loan amount of 300,000, the second line is the repayment of the month default is 0, the third line is the total repayment month 20 years 240 months, the fourth line is a formula, according to the number of months to calculate the monthly repayment amount, the figure can be seen in the first month of 2750RMB.

The first scheme name added is "2nd year", specify changing cells as C2 cell (number of months repaid), OK

The Excel Pop-up dialog asks for a change value for this scenario, and we specify the 2nd year, so the corresponding setting here is 12.
