It allocates 60% of gross income to the origin city’s category budget and applies each destination category’s relative cost. The equivalent salary adds the total category difference to your income. The monthly difference is the same category difference divided by 12; it is not take-home pay or guaranteed savings. Household size, childcare and your actual lease are not inputs to this calculation.

What rent estimates are available for Rocklin, CA and Brentwood, CA?

The modeled two-bedroom rents are $2,880/month in Rocklin, CA and $3,150/month in Brentwood, CA. Where available, the source is a city median of HUD FY2026 ZIP-level estimates; otherwise a saved metro table is used. City adjustments may also apply.

How should I use this comparison before moving?

Use it to shortlist locations, then replace modeled costs with a current housing quote, employer-confirmed income, commute costs, insurance and your household's other expenses. Add one-time moving costs separately. Source years differ and the saved datasets are not a live price feed. Read the methodology for the formulas and fallback rules.
