Then we can draw a right triangle with angle θ as in the figure
and deduce from the Pythagorean Theorem that the third side has length
This enables us to read from the triangle that

PRFC: Periodic Rate Finance Charge
Formula:
If your APR is 7.65%*, you have a 29day billing cycle, and an average daily balance of $6,000, the formula would be as follows:
*7.65% = 7.65/100 = .0765 Continue reading PRFC:
