Financial experts universally advise keeping total housing costs (rent/mortgage, taxes, insurance) at or below 28% to 30% of gross income, or under 35% of take-home pay.
Keep total transportation costs (auto loan, gas, maintenance, and insurance) under 10% to 15% of your take-home income.

Most budgeting ratios work best when calculated using net (take-home) income since that is what actually enters your bank account.
