Mortgage Calculators
Six calculators for the questions people actually ask about a mortgage: when it ends, what each payment really pays for, whether refinancing clears its costs, and what a house costs you every month after tax.
- Mortgage Payoff CalculatorYour payoff date and how much an extra payment saves.
- Amortization CalculatorSee how each mortgage payment splits between interest and principal, plus your payoff date and total interest.
- Refinance Break-Even CalculatorEnter closing costs and your old and new payments to see how many months until refinancing pays for itself.
- Mortgage Recast CalculatorSee your new monthly payment after a lump sum recast, and how much the payment drops.
- Property Tax CalculatorTurn an assessed home value and a local tax rate into an annual and monthly property tax number.
- How Much House Can I Afford?Enter income, down payment, rate, term and your comfort zone to estimate the house price you can carry.
Which one do you need?
- Keeping the loan, adding money each month? Start with the payoff calculator — it answers “when am I done and what does it save me.”
- Being offered a new rate? Use break-even before anything else; a lower rate that never recoups closing costs is a loss.
- Got a lump sum? Recast lowers the payment, extra payments shorten the term — the two calculators show the difference side by side.
