What a $100k salary actually gives you
A $100,000 gross salary works out to roughly $6,300 a month in take-home pay after taxes and typical deductions. The 28% housing guideline points to keeping total housing costs at or under about $1,764 a month.
At today's rates, that comfortably supports a home in the $300,000–350,000 range, before adjusting for your down payment, other debts, and property taxes in your area.
Why price alone doesn't tell the story
Two buyers with identical salaries can afford very different homes. Down payment size, mortgage rate, existing car and student loans, and local property taxes all pull the number up or down.
Enter your real figures above and the calculator will show whether the home you're eyeing actually fits, or how much room you have to stretch.
Buying on $100k: the 20% down decision
On a $325,000 home, 5% down is $16,250, 10% is $32,500, and 20% is $65,000. PMI at 5% down runs roughly $135–$200 a month until you reach 20% equity, which typically takes 6–9 years on a normal amortization schedule.
Closing costs at this price land around $6,500 to $16,250. The honest math: waiting two years to save the full 20% only wins if home prices in your area stay flat. If they rise 4% a year, the home you're waiting on costs $26,500 more, considerably more than the PMI you'd have paid.
A six-figure income also means your property tax bill starts to matter a lot. On a $325,000 home, the difference between a 0.6% and a 1.8% effective tax rate is about $325 a month, larger than most rate shopping will ever save you. Check the county rate before you fall for a specific house.

Frequently asked questions
What house price can I afford on $100k?
On a $100,000 salary, a home priced around $300,000 to $350,000 is generally affordable, roughly $1,760 a month in total housing costs following the 28% guideline.
What monthly payment fits a $100k income?
Take-home pay on a $100,000 salary is around $6,300 a month, so the 28% guideline points to about $1,764 for mortgage, insurance, taxes, and upkeep combined. On a $325,000 home, taxes and insurance alone often account for a quarter to a third of that figure.
How much house can I afford with a $100k salary and no debt?
With no other debt payments and a 10% down payment, most buyers on $100,000 qualify in the $350,000–$400,000 range. Staying nearer $325,000 keeps total housing costs at about 28% of take-home pay and leaves real room to save.
Should I wait to save 20% down on a $100k income?
Not automatically. PMI on a 5% down $325,000 loan is roughly $135–$200 a month, while two more years of 4% price growth would add about $26,500 to the purchase price. Buying earlier with PMI often costs less than waiting.
Do I need a 20% down payment?
No. On a $325,000 home, 20% down is $65,000 and removes PMI, but 10% ($32,500) and 5% ($16,250) are both common, and FHA allows 3.5%. A larger down payment lowers the loan and the monthly cost; it is not a requirement.
