Hello @eber219
Thank you very much for using our plugin. The formula in your entry is for the monthly payment. It subtracts the proportional part of the residual value. If you don’t want to include residual value in your project, you should edit two formulas:
The formula for the monthly payment:
prec((fieldname2*fieldname7/1200*pow(1+fieldname7/1200,fieldname8))/(pow(1+fieldname7/1200,fieldname8)-1),2)And the formula to calculate the interest amount:
prec(fieldname9-fieldname2,2)Best regards.
