I was talking with a friend about Payday loans (neither of us is getting one, just merely curious) and the APRs they state aren't really true. So, I was trying to figure out an APR based on the following criteria:
Loan amount: $100 "Finance Charge": $30 every payday. Loan starts paying back on 5th renewal, at 5% of the original balance.
So, the schedule of payments is: 30 (just fee) 30 (just fee) 30 (just fee) 30 (just fee) 35 (Fee of $30 plus $5 of principal) 33.5 (Fee of $28.5 plus $5 of principal) 32 (Fee of $27 plus $5 of principal) etc. 6.5 (Fee of $1.5 + $5 of principal)
The total paid is $535 for a 100 loan, over approximately 345 days.
What would be the APR? 534%? ($535/$100) * (345/365) / 100?
