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.
