Mortgage calculators
Each one takes your own figures and runs entirely in your browser. Pick the question you are trying to answer.
- Mortgage calculatorMonthly payment, full PITI and a complete month-by-month amortization schedule.
- RefinanceWhat a rate-and-term refinance costs, and how long it takes to repay its closing costs.
- Cash-out refinanceReplacing your mortgage with a larger one and taking the difference as cash.
- HELOCA variable line behind your first mortgage, with the payment step-up modelled.
- Home equity loanA fixed second mortgage: one lump sum, one rate, one payment that never moves.
- Mortgage recastA lump sum plus a re-amortization, keeping your existing rate and payoff date.
- Extra paymentsWhat extra principal does to your payoff date and your total interest.
- Invest vs extra paymentsMoney sent to principal earns your rate for certain. Investing might earn more.
- Home affordability calculatorWork out a home price from income, debts, cash on hand and your own housing-to-income and debt-to-income ceilings.
- Closing cost calculatorClosing costs line by line, with fees, prepaids and escrow kept apart and the cash to close for a purchase or a refinance.
- Debt-to-income calculatorFront-end and back-end debt-to-income ratios from itemized debts, with the student loan rules, the limits we can cite and the most housing payment that fits.
Which calculator answers which question
All nine tools run on the same engine and differ only in which questions they ask.
| If you are asking… | Use |
|---|---|
| What would my payment be on a house I am buying? | Mortgage calculator |
| Is refinancing worth it, and when does it pay for itself? | Refinance calculator |
| What does taking cash out of the house cost? | Cash-out refinance |
| Can I borrow without giving up my current rate? | HELOC or home equity loan |
| Can I lower my payment without refinancing? | Mortgage recast |
| How much sooner would extra principal clear the loan? | Extra mortgage payment |
| Should spare money go to the mortgage or the market? | Invest vs extra payments |
| What price can I afford at all? | Home affordability |
Every one of them costs its options over a holding period you set, and none of them fetches a rate or sends a figure anywhere.
They share a single calculation engine, so a figure entered in one is already filled in when you open another, and two calculators can never disagree about the same loan. What differs is scope: a focused page asks only for what its own question needs, which is why the refinance calculator does not ask about HELOC draw periods.
If you would rather see everything at once, the full comparison costs every strategy against keeping your mortgage on one set of figures.
