Mortgage & Home Equity calculators
Home equity is often the largest — and cheapest — source of credit a household has, but the right way to tap it depends on your existing mortgage rate, how much you need and how long you will carry the balance. These calculators estimate what a lender may let you borrow, what a HELOC will cost during and after the draw period, and whether replacing your first mortgage with a cash-out refinance makes sense compared with adding a HELOC.
If you’re buying, the mortgage and house affordability calculators show the full monthly payment and the price your income supports.

Which home calculator do you need?
- Buying a home? The mortgage calculator shows the full monthly payment with taxes, insurance, PMI and HOA dues, and what extra payments save.
- How much could I borrow? The home equity calculator applies lender CLTV limits of 75% to 90% to your home’s value and mortgage balance.
- What would the payments be? The HELOC payment calculator shows the interest-only draw payment and the jump when repayment starts, with a rate stress test.
- HELOC or fixed-rate loan? The HELOC vs home equity loan calculator compares payments, interest and fees side by side.
- Should I refinance instead? The cash-out refinance vs HELOC calculator compares total cost over your time horizon and finds the break-even year.
- Can I afford a home? The house affordability calculator finds the price your income and debts support under each loan program’s DTI limits.
The number that matters most: your current mortgage rate
If your first mortgage has a low fixed rate, keeping it and borrowing only what you need with a HELOC or home equity loan is usually cheaper than refinancing everything at today’s rates. If your current rate is above the market, a cash-out refinance can lower the cost of the whole balance. Either way, remember that your home secures the debt — borrow for purposes that improve your finances, and budget for the repayment period, not just the draw period.
