Real estate calculations in one place
Choose a task to see its inputs. Solve for a loan payment, principal, interest rate or term; estimate a buyer’s housing budget; calculate a remaining balloon balance; or compare monthly and biweekly payments.
Plan for property costs and changing payments
Buyer qualifying includes principal, interest, property tax and homeowners insurance, plus entered mortgage insurance and HOA dues. Selecting a U.S. state supplies editable property assumptions and a dated typical home-value reference. Qualifying ratios are planning examples and do not establish loan eligibility.
ARM mode projects resets from your assumptions. APR mode estimates the borrowing rate after entered upfront finance charges. Other modes compare rent with buying, project appreciation, combine an interest-only first loan with a second loan, and count calendar days for planning a closing.
Each mode explains its assumptions below the result. For FHA, VA, USDA and conventional product-specific estimates, use our mortgage calculator. Compare up to four scenarios and export outlined reports in Excel, Word, PDF or JPG.
