PMI math on a $120,000 salary

Putting down less than 20% on a $120,000 income triggers PMI at roughly 0.5% of the loan per year. On a $343,000 home, that is $1,655/year in extra cost until you reach 20% equity. Saving to the 20% threshold eliminates this entirely and reduces monthly payment by $138/month.

Do not include rent — only recurring debt obligations.

Less than 20% of the home price triggers PMI (private mortgage insurance).

Buying and selling within 5 years rarely covers transaction costs.

Frequently asked questions

How much house can I afford on a $120,000 salary?

On a $120,000 salary with 10% down and a 7% mortgage rate, you can afford a home up to $343,000. Using the conservative 20% down at 6.5%, that rises to $367,000. These figures assume no existing monthly debts. The 28/36 DTI rule limits your housing payment to $2,800/month.

What is the 28/36 rule for a $120,000 income?

The 28/36 rule says your housing costs should not exceed 28% of gross monthly income and total debts should not exceed 36%. On a $120,000 salary, that means maximum housing costs of $2,800/month and maximum total debt payments of $3,600/month. Most conventional lenders use these thresholds.

How much should I put down on a $120k salary?

With a $120,000 income, a 10% down payment is $12,000 and a 20% down payment is $24,000. The 20% threshold eliminates PMI (typically 0.5% of the loan annually), which saves $1,655/year at this income level. FHA loans allow 3.5% down but require mortgage insurance for the life of the loan.

Can I afford a house on $120k with existing debt?

Existing debts reduce your maximum home price directly. The 36% back-end DTI limit means all monthly debts — car payment, student loans, credit cards, and your new mortgage — cannot exceed $3,600/month combined. Each $500/month in existing debts reduces your maximum home price by roughly $70,000-$90,000 at current rates. Use the calculator above to model your exact situation.
