Useful homeowner calculators, not homework.
Quick tools for buying, budgeting, repairs, insurance, taxes, and resale decisions. Use the calculators first, then read the full guides only when you need the details.
Which calculator should you use first?
Start with the decision you are trying to make. Then move to the next tool only if that number changes the answer.
Buying & moving
Home Affordability Calculator
Find a realistic purchase range before the listing sells you emotionally.
Open tool →PaymentMortgage Calculator
Estimate principal, interest, taxes, insurance, PMI, and monthly payment pressure.
Open tool →Cash planningMoving Cost Calculator
Estimate moving-week cash needs, setup costs, deposits, and cushion.
Open tool →Do not forget the moving-weekend costs
After you run the affordability and mortgage calculators, price the move itself too. Truck or vehicle rental, fuel, deposits, setup runs, and first-week surprises can hit before the first payment is even due.

How these calculators are built
OwnerHacks calculators are planning tools. They are designed to make homeowner tradeoffs easier to see before a decision gets expensive.
- Mortgage and affordability tools lean on standard payment, DTI, tax, insurance, and cash-planning logic.
- Maintenance, insurance, and reserve tools use practical ranges so homeowners can pressure-test risk instead of chase exact predictions.
- Reference points include CFPB, HUD, Freddie Mac, NAIC, FEMA, Florida DOR, and other official sources where relevant.
The calculator result should be treated as a starting point, not personal financial, legal, tax, insurance, lending, or appraisal advice.
Example scenario: use more than one calculator
A buyer may pass the affordability calculator but still need the mortgage calculator, moving cost calculator, and emergency fund calculator before the decision is safe.
Practical read: one good number is not enough. The better move is checking monthly payment, cash after closing, insurance exposure, and first-year repairs together.
