Frequently Asked Questions: Markham, IL vs Jennings, MO

How do the cost estimates for Markham, IL and Jennings, MO compare?

Jennings, MO has a modeled overall cost index 14.9% lower than Markham, 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 Markham, IL, the model estimates $133,992 in Jennings, MO. 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 Markham, IL and Jennings, MO?

The modeled two-bedroom rents are $1,340/month in Markham, IL and $1,100/month in Jennings, MO. 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.
