- How is a loan's monthly payment calculated?
- It's the standard amortising-loan formula: the payment that fully repays the principal plus interest over the term. A higher rate or shorter term raises the monthly payment.
- How much do extra payments save?
- Enter an extra monthly amount under Advanced options and the calculator re-amortises the loan: it shows your new payoff date, the months you cut off the term, and the total interest you avoid. Even a small extra payment can save years and thousands in interest.
- Can I use this for an acquisition loan?
- Yes — for the financing side of buying a business, GradeThisDeal's deal calculator also computes DSCR and cash-on-cash on top of the payment.
