15-year fixed rate, 10-20% down, and payment at or below 25% of monthly take-home pay. That is the Ramsey framework. Plug in your numbers and see if the house fits the budget.
Term: 15 years fixed (Ramsey rule)
Estimates only. Not financial advice.
The Dave Ramsey mortgage rule: use a 15-year fixed rate mortgage, put at least 10% down (20% to avoid PMI), and keep your total monthly housing payment at or below 25% of your monthly take-home pay. On a $300,000 home with 20% down at 6.5%, the 15-year payment is about $2,090 - meaning you need at least $8,360/month take-home to follow the rule.
Ramsey's framework has four core points: 15-year fixed rate loan, at least 10% down (20% preferred), total housing payment at or under 25% of monthly take-home pay, and a conventional loan only. Each piece reinforces the others. A 15-year term combined with a solid down payment keeps the payment high enough to build equity fast but tight enough to force honest budgeting before signing anything.
On the interest question, the numbers are hard to ignore. A $250,000 loan at 6.5% costs roughly $139,000 in total interest over 15 years. The same loan stretched to 30 years costs around $317,000 in interest - more than the original loan balance. The shorter term roughly halves what you pay to the bank over the life of the loan.
The 25% take-home rule is where Ramsey diverges most sharply from standard lending guidelines. Most banks qualify buyers at up to 28% of gross income for housing, or up to 43% total debt-to-income. Ramsey targets 25% of net pay - what actually lands in your bank account after taxes and deductions. Because take-home pay is typically 70-80% of gross, Ramsey's rule is considerably tighter in practice than the lender's version.
On down payments, Ramsey accepts 10% for first-time buyers but treats 20% as the real target. At 20% down you avoid private mortgage insurance, which can add $100 to $300 a month to your payment depending on the loan size and lender. That monthly saving is real money that can go toward retirement or an emergency fund instead.
The philosophy behind all of it is conservative by design. Ramsey's listeners have often dug out of serious debt. The 25% rule leaves breathing room for retirement contributions, healthcare costs, and the irregular expenses that sink household budgets when there is no margin. Owning a home outright in 15 years rather than carrying a mortgage into your 60s is the intended destination.

Ramsey recommends a 15-year fixed rate mortgage with at least 10% down (20% preferred), a monthly payment no higher than 25% of your monthly take-home pay, and a conventional loan with no PMI if possible. The goal is to pay off the home faster and avoid being house-poor.
Take your monthly take-home pay (after taxes and deductions) and multiply by 0.25. That is the most your total housing payment should be. So if you bring home $6,000 per month, your mortgage principal, interest, taxes and insurance combined should stay at or below $1,500.
A 15-year term builds equity faster and cuts total interest paid roughly in half compared to a 30-year loan. The higher payment forces discipline and results in owning the home free and clear in half the time.
Ramsey's advice is straightforward: buy a less expensive house, save a larger down payment, or wait. In his framework, stretching to afford a house is how people end up financially stressed for decades.
No. Ramsey's rule assumes at least 20% down to avoid PMI. If you put down less than 20%, add estimated PMI (typically 0.5% to 1% of the loan per year) to your monthly payment before comparing against the 25% limit.
