What this calculator does
This calculator checks whether a salary covers the cost of living in San Francisco. It estimates take-home pay with San Francisco taxes, subtracts a monthly budget pre-filled with starting estimates for one adult, and shows what is left over and the income you would need to break even. Housing is the dominant cost, but groceries, dining and services are also expensive. Many residents offset some of that by skipping car ownership.
How to use it
- Enter your gross salary and filing status.
- Replace each budget line with your own numbers where you know them.
- Add childcare if it applies.
- Read the leftover amount and the break-even income.
The formula
Left over = take-home pay ÷ 12 − (housing + utilities + groceries + transportation + health + childcare + other). Break-even income = salary × spending ÷ monthly take-home pay.

What drives the cost of living in San Francisco
San Francisco has some of the highest rents and home prices in the country, with a large share of housing in older buildings covered by the city's rent ordinance. Neighborhoods range from the Mission and SoMa to the Sunset, Richmond and Bernal Heights, and fog belt western neighborhoods often cost less than central ones.
San Francisco residents pay California income tax, which runs from 1% to 12.3% plus a 1% Mental Health Services Tax on income above $1 million. There is no separate San Francisco personal income tax; the city's own taxes fall on businesses through gross receipts and payroll-based measures.

- Budgeting from gross pay instead of take-home.
- Leaving out irregular costs like travel, gifts and car repairs.
- Treating starting estimates as facts — they are placeholders for your numbers.
- Comparing cities without adjusting taxes; use the Compare Cities tools.
