Hi everyone,
a close friend of mine asked to borrow some money to help jumpstart his new organic catering business, and we agreed on a small interest rate for the duration of the loan.
To keep our friendship professional and transparent, I need to find a very precise method to calcular período entre datas (https://calculadorahoras.com.br/datas/) so that the final repayment amount is fair for both of us.
I want to make sure I am doing the math correctly to avoid any awkward conversations about money down the line. Does anyone have a reliable template for this type of calculation?
Thanks in advance.
