How do you write a receipt for a loan?

To write a receipt for a loan, include the date of the transaction, the names of the borrower and lender, the loan amount, and the repayment terms. Clearly state that the amount is received as a loan and specify any interest rate if applicable. It's also helpful to include a description of the purpose of the loan and a signature line for both parties. Finally, provide a copy to the borrower for their records.
