How to Use This Mortgage Income Calculator

This calculator works in reverse — you enter the home you want and it tells you what income you need to qualify.

Quick Calculator

Enter your Target Home Price, Down Payment %, Interest Rate, Loan Term, Monthly Debts (all recurring debt payments), and your lender's Max DTI Limit. The calculator reverse-solves to show the minimum annual income you need, your monthly payment, and both front-end and back-end DTI ratios.

Advanced — Income by Home Price, Program Comparison, DTI Check

The Income by Home Price tab shows a table of 7 home prices ($200K–$1M) with the minimum income needed at each. The Loan Program Comparison shows side-by-side income requirements for Conventional, FHA, VA, and USDA loans — useful since each program has different DTI limits and down payment requirements. The DTI Check tab breaks down your front-end and back-end ratios in detail.

Professional — Full Qualification, Geographic Adjustment, Dual Income

The Full Qualification tab checks credit score, down payment, DTI, and PMI requirements for each loan program simultaneously. Geographic Adjustment shows how property tax rates across 5 major states affect the income required for the same home price. Dual Income shows how adding a co-borrower expands your maximum qualifying home price.

How Minimum Income Is Calculated

Monthly Housing Cost (PITI) = Principal & Interest + Property Tax + Insurance

Back-End DTI = (Monthly Housing + All Monthly Debts) / Monthly Gross Income

Solving for income:
Required Monthly Income = (Monthly Housing + Monthly Debts) / DTI Limit
Min Annual Income = Required Monthly Income × 12

Example — $400,000 home, 10% down, 7.0% rate, 30-yr, $500/mo debts, 43% DTI:
Loan = $360,000 → P&I = $2,395/mo
Property Tax (1%) = $333/mo | Insurance = $117/mo
Total Housing = $2,845/mo
Required Monthly Income = ($2,845 + $500) / 0.43 = $7,779/mo
Minimum Annual Income = $7,779 × 12 = $93,349/yr

Example: Maria Qualifies Solo vs With Co-Borrower

Maria wants a $450,000 home in Denver, CO with 10% down

Maria earns $85,000/year. Her monthly debts are $600. Rate: 7.0%, 30-year, 43% DTI limit.

Home Price$450,000
Down Payment (10%)$45,000
Loan Amount$405,000
Monthly P&I$2,694
Monthly Tax + Insurance$506
Total Housing (PITI)$3,200
Minimum Income Required$104,558/yr
Maria's Income$85,000/yr — NOT ENOUGH
Partner adds $30,000/yrCombined: $115,000/yr — QUALIFIES

By adding a co-borrower earning $30,000/year, they easily qualify. Alternatively, Maria could switch to FHA (50% DTI) which drops her solo minimum to $89,640/year, letting her qualify alone — but with MIP costs added.

Frequently Asked Questions

The income needed depends on your target home price, interest rate, down payment, existing debts, and the lender's DTI limit. For a $400,000 home at 7% with 10% down and $500/month in debts, you typically need around $93,000–$105,000 in annual gross income. Use this calculator to get the exact number for your situation.
DTI is total monthly debt payments divided by gross monthly income, expressed as a percentage. Lenders calculate two numbers: front-end DTI (housing costs only — should be under 28%) and back-end DTI (all debts including housing — conventional max is typically 43%, FHA can go up to 50%). A lower DTI means you qualify for more home or need less income for the same home.
FHA allows a higher back-end DTI (up to 50% with compensating factors vs 43% conventional), so you can qualify with slightly less income. However, FHA requires MIP (mortgage insurance premium) for the life of the loan if you put less than 10% down — this adds $100–$300/month. The lower qualification bar comes with higher long-term costs.
Yes. Co-borrowers have their incomes combined for qualification purposes. Both borrowers' debts are also included, so the benefit depends on the co-borrower's debt load. A co-borrower with $80,000 income and $0 debts significantly boosts your power. One with $80,000 income but $2,000/month in debts adds less. Use the Dual Income tab to see your combined maximum home price.
Property taxes are factored into your monthly PITI payment for DTI purposes. States like Illinois (2.07%) and New Jersey (2.21%) have taxes so high they can add $800–$1,000/month to your payment on a $500,000 home. This directly increases the income you need to qualify. Texas at 1.60% requires significantly more income than Florida at 0.80% for the same priced home — see our Geographic Adjustment tab for a comparison.
