Popular scenarios
What are you considering?
Buying a car
See the full monthly cost of a vehicle, not just the loan payment.
Buying a home
Check cash-flow room after housing costs, even if a lender might approve you.
Renting a home
Factor in utilities, fees, and move-in cash, not only the listed rent.
Comparing a job offer
Compare take-home pay, benefits, and work costs, not base salary alone.
Moving
Estimate relocation cash needs and how your monthly costs may change afterward.
Repairing or replacing something
Compare repair and replacement costs and the budget pressure of each path.
Another major purchase
Estimate affordability for a large purchase that does not fit another scenario.
Why the math is shown in plain view
Every scenario explains the inputs, assumptions, and limits. No mystery score pretending to be certainty.
Full-cost thinking
Payments matter, and so do insurance, fees, maintenance, deposits, and commute costs.
Cash-flow room
We estimate what may remain each month after the decision costs you included.
What-if checks
Test income and key assumptions instead of trusting one optimistic case.
