See the cost, not just the payment.
Every tool keeps the assumptions visible so you can change one variable and understand what drives the result.
Visible assumptions
Rate, term, amount and fees stay on the page. Nothing is hidden behind a single headline number.
Total cost
Payment, interest and total repaid are shown together so a cheaper monthly figure is not mistaken for a cheaper loan.
