Car & Home Affordability
This gives you a blunt estimate of what looks comfortable, stretch, or risky based on income, debts, rates, and down payment setup. Debt now scales against income instead of acting like a flat hit.

Quick notes
How to read this
Comfortable is the number that is a lot less likely to make your month feel stupid.
Stretch means possible, but you will feel it more.
Risky means the payment starts getting too aggressive for normal breathing room.
Important
Reality check
Car math now uses debt plus car cost as a percent of income, so the same debt hurts more at lower income and less at higher income.
Home math uses front-end and back-end ratios, which is a lot closer to how real affordability gets judged.
PMI, closing costs, dealer fees, taxes at signing, utilities, and maintenance are still not fully modeled.
