Sales Price/Down Payment
One of the unique features of this calculator is its ability to work with
not only Loan Amount, but with Sales Price and Down Payment. You
can enter two values to find the third (e.g., enter Price and Down
Payment to find Loan Amount). You may also enter the Down
Payment in both percent or dollar format. For example, to enter
20%, enter 20 and press the d key (you do not have to label it as
a percent). Or enter $20,000 (e.g., 2 0 ) d).
Note: A number under 100 entered as the Down Payment is assumed to be a
percentage.
Note: When using P, d, and l keys, it's recommended that you always enter
the two known values (Price and Down Payment), then solve for the third (Loan
Amount), before calculating financial values.
Finding Loan Amount Based on Sales Price and Down Payment
Find both the Down Payment dollar amount and loan amount if the
sales price is $250,000 and you're planning to put 20% down.
