How do the cost estimates for Rockton, IL and Grand Blanc, MI compare?

Grand Blanc, MI has a modeled overall cost index 14.8% lower than Rockton, IL. This is a broad model comparison, not a survey of today's prices or a forecast of your household spending. Some cities use adjusted regional fallback data.

What does the equivalent salary mean?

At a $150,000 salary in Rockton, IL, the model estimates $138,106 in Grand Blanc, MI. 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 Rockton, IL and Grand Blanc, MI?

The modeled two-bedroom rents are $1,170/month in Rockton, IL and $1,080/month in Grand Blanc, MI.

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.
