Why we built these calculators
Lending money to family works best when both sides look at the same numbers. These calculators answer the questions we hear most from lenders and borrowers: what will the payment be, how much interest is that in total, what rate does the IRS expect, and when will the loan be paid off.
Every tool is free, needs no account, and runs entirely in your browser. When you are ready to make the loan official, the same numbers flow straight into a tracked loan or a written agreement, without re-typing anything.
