Decision tools
A calculator gives you a number. These tools answer the question behind it. Enter your situation once and get a plain verdict, the numbers behind it, and a link you can share or come back to.
- Check a house →
Can I afford this house?
Your monthly payment, debt-to-income, the cash to close, and whether buying beats renting, in one flow.
- Check a car →
Can I afford this car?
The real monthly cost, the 20/4/10 guideline, your debt-to-income and the cash you need at signing.
- Check a refinance →
Should I refinance my mortgage?
Monthly saving, break-even, the cost over your stay and lifetime interest, compared like for like.
- Check my retirement →
Am I saving enough to retire?
What you will have, what you need, the gap and the monthly fix, in today’s dollars.
How they work
- They reuse the same tested calculations as the individual calculators, so the numbers match those pages.
- Every assumption is stated on the page, and the verdict rules are guidelines, not lender decisions.
- Everything is calculated in your browser. Saved scenarios stay on your device; the link carries only the numbers you entered.
- See how we test and verify and the public corrections log.
