Frequently Asked Questions
Should I use monthly or annual figures?
Use one consistent period for every amount and rate in the relationship. If a form specifies an annual rate or a monthly amount, follow that label rather than mixing time periods.
Does the result include fees and tax?
Only the costs and taxes represented by the inputs and formula are included. A real transaction can include other charges, so compare the estimate with the underlying agreement or statement.
