For example, I want to put $2,000 Drive-off and I don’t want to keep having to adjust the down payment to get to that value when other deal terms change. I would want to be able to enter that value into the calculator and any changes only affect the monthly payment.
OR
I need my monthly payment to be under $400/month, but I am willing to put more down to get there, and want the down payment to update with changes in the deal terms to keep me under $400/month without having to increase/decrease down payment manually.
