Monthly debt calculator

Add up your recurring monthly debt payments — the figure a mortgage payment or affordability calculator's "Monthly debts" field is asking for, and the starting point for a payoff plan.

What counts as a "monthly debt" for a mortgage? Lenders use it to calculate your back-end debt-to-income (DTI) ratio — recurring, required minimum payments on money you already owe. That means car loans, student loans, credit card minimum payments, personal loans, payments on any other property you carry (a second home or a rental), and things like alimony or child support. It does not include groceries, utilities, subscriptions, other everyday spending, or rent you're currently paying if you'll be moving out once you buy — none of that is debt.

Rental property: lenders typically offset the payment with about 75% of documented rental income — enter the payment minus that offset, or $0 if the offset covers it.
