Max Loan Calculator
Enter the monthly payment you can afford, the annual rate, and the term. We solve for the maximum loan amount (principal) that fits that payment. Useful for budgeting before you shop.
Max loan from payment
Enter values to calculate.
How it works
We reverse the standard payment formula: given payment Pmt, rate r, and term n, principal = Pmt × [(1+r)^n − 1] / [r(1+r)^n]. This gives the loan amount that produces that payment.
When to use it
Use it to set a price range for a car or home, to see how rate changes affect how much you can borrow, or to check affordability.
Frequently asked questions
Does this include taxes and insurance?
No. For housing, use a payment that is P&I only, or subtract estimated taxes and insurance first.
Same as mortgage affordability?
Similar idea. Mortgage affordability often starts from income and DTI; this starts from payment.
