Details
These notes make the assumptions explicit, especially where the same search query can mean slightly different things.
APR is broader than the interest rate because it can include certain fees charged to get the loan.
The estimate fits fixed monthly payments. Irregular payment schedules, teaser rates, or variable rates need more specific disclosures.
The calculator treats fees as reducing the net amount received, then annualizes the cost of the payment stream.
Benchmarks
The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.
APR may be close to the interest rate when fees are small.
Fees can make APR meaningfully higher than the stated interest rate.
The same fee can produce a higher APR on a shorter loan term.
