Expert Tip

Lenders prefer a back-end DTI ratio of 36% or below, with 43% being the standard limit for Qualified Mortgages.

How this Calculator Works

This calculator computes your Debt-to-Income (DTI) ratio, a metric lenders use to measure your ability to manage monthly payments. It divides total monthly debt payments by gross monthly income.

Formula & Methodology

DTI Ratio = (Total Monthly Debt Payments / Gross Monthly Income) * 100 - Total Monthly Debt Payments is the sum of mortgage, student loans, and credit card minimums.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

A borrower has monthly debt payments of $2,000 and earns a gross monthly income of $6,000. 1. Divide monthly debt by monthly income: $2,000 / $6,000 = 0.3333. 2. Multiply by 100: 0.3333 * 100 = 33.33%. Result: The borrower's Debt-to-Income (DTI) ratio is 33.33%.

FAQ

What is Capitalization Rate (Cap Rate) in real estate?
Cap Rate = Net Operating Income (NOI) / Current Property Value. It measures an unleveraged property's natural rate of return independent of debt financing.
How does Cash-on-Cash Return differ from Cap Rate?
Cash-on-Cash Return calculates Annual Net Pre-Tax Cash Flow divided by Total Out-of-Pocket Cash Invested (down payment + closing costs + rehab). It incorporates debt leverage effects.
What DTI ratio limits do mortgage lenders enforce?
Most conventional lenders prefer a front-end housing DTI under 28% and a total back-end debt DTI under 36% to 43% (up to 50% for FHA/VA backed loans).
