Frequently Asked Questions
Common questions about the free online apr calculator.
The annual percentage rate is the true yearly cost of a loan once the interest rate and the
fees you pay are both counted.
Fees reduce the amount you actually receive while the repayments stay the same, so the
effective cost of that money rises.
It repeatedly tests rates until the present value of every monthly payment equals the amount
financed, a method called bisection.
Nominal APR is the monthly rate multiplied by twelve, while effective APR also counts the
effect of compounding during the year.
Any fee you enter in the fees box, such as an arrangement fee, broker fee or valuation charge
paid up front.
It is the loan amount minus the fees paid from the proceeds, and it is the figure the true
rate is measured against.
It is everything the loan costs you beyond the money borrowed, which is all the interest plus
every up-front fee.
The tool reports that the rate is not solvable when the fees are so large that the repayments
never cover them.
