Formula and method
Assumptions and limitations
Fixed monthly loan payments and upfront withheld fees. This is an economic cash-flow calculation, not a regulated APR/APRC disclosure or country-specific compliance result.
Worked example
With no fees, a nominal 12% loan with monthly interest has a monthly cash-flow rate of 1%, nominal annual equivalent of 12% and effective annual cost about 12.6825%.
What the result means
Estimate the cash-flow borrowing rate when fees reduce the cash you receive.
Common questions
How is the calculation performed?
Solve net proceeds = monthly payment × discounted-payment factor for the monthly cash-flow rate. Nominal annual equivalent = monthly rate × 12; effective annual = (1 + monthly rate)^12 − 1.
What does the model leave out?
Fixed monthly loan payments and upfront withheld fees. This is an economic cash-flow calculation, not a regulated APR/APRC disclosure or country-specific compliance result.
