How it works
The 30 percent rule multiplies gross monthly income by 0.30. The 40x rule divides yearly income by 40. The debt-adjusted figure keeps total housing and debt under 36 percent.
Worked example
With 5,500 a month, the 30 percent rule gives 1,650, the 40x rule gives 1,650, and 300 in debt payments leaves 1,680 under the 36 percent limit.
