Mortgage & Real Estate

About Mortgage & Real Estate Calculators

Buying or refinancing a home is one of the largest financial decisions most people make. Our 16 mortgage and real estate calculators help you estimate monthly payments, total interest, affordability limits, and whether renting or buying makes more sense for your timeline.

Key tools include FHA Loan Calculator, VA Mortgage Calculator, Rental Property Calculator, APR Calculator, Down Payment Calculator, Rent vs. Buy Calculator. Enter your loan amount, APR, taxes, insurance, and down payment to see a realistic payment breakdown.

Common use cases

• Pre-approval planning: know your payment before visiting lenders.
• Refinance analysis: compare current loan vs new rate and closing costs.
• Investment property: model rental income and cash-on-cash return.

Mortgage Planning Tips

Always compare at least two lender quotes. Use the Mortgage Calculator and House Affordability Calculator together to stay within a comfortable debt-to-income ratio. Read our mortgage guide for first-time buyers for more context.

First-Time Buyers

Save for down payment with the Down Payment Calculator. FHA and VA programs allow lower down payments for qualifying borrowers; model them with the FHA Loan Calculator and VA Mortgage Calculator. Know your debt-to-income ratio before applying.

Homeowners and Investors

Existing owners use the Refinance Calculator, Mortgage Payoff Calculator, and Home Equity Loan Calculator. Rental investors start with the Rental Property Calculator and Real Estate Calculator hub.

How to pick a housing calculator

Match the form to the paper in your hand. A Loan Estimate maps to the Mortgage Calculator for PITI. A pre-approval conversation without a price yet maps to House Affordability. A refinance quote with closing costs maps to the Refinance Calculator, not a generic payment tool that ignores fees. FHA and VA worksheets have their own pages because mortgage insurance and funding fees change the cash due at closing.

All 16 housing tools document amortization or cash-flow math, a round-number example, and limits such as credit overlays they cannot see. Calculations stay on your device. Pair a number with mortgage basics when the decision is whether to buy, not only what the payment is.

Each listing is the stable URL for that housing tool. Read the one-sentence job description before opening five similar pages with the same loan amount.

• FHA Loan Calculator — This FHA Loan Calculator estimates principal, interest, and FHA mortgage insurance on a government-insured loan. You enter purchase price, down payment, rate, and term to see how upfront MIP rolled into the loan and annual MIP paid monthly change the payment versus a conventional loan with PMI.
• VA Mortgage Calculator — This VA Mortgage Calculator estimates monthly principal and interest on a VA-backed loan plus the VA funding fee, which most veterans finance into the loan. Enter purchase price, down payment if any, rate, and term to see payment with first-use or subsequent-use funding fee assumptions and how exempt status changes the math.
• Rental Property Calculator — This Rental Property Calculator builds an investor-style pro forma from purchase price, financing, gross rent, vacancy, and operating expenses. It reports net operating income, monthly cash flow after debt service, cap rate, and cash-on-cash return so you can compare rentals on economics rather than curb appeal alone.
• APR Calculator — This APR Calculator converts a quoted note rate, loan amount, term, and finance charges into an annual percentage rate. APR spreads certain upfront fees over the loan life so you can compare two lender offers that have the same rate but different closing costs. Use it when you are down to two Loan Estimates, not when you only need a monthly payment.
• Down Payment Calculator — This Down Payment Calculator totals the cash you need at closing by combining down payment dollars with estimated closing costs on a purchase price. Compare five percent versus twenty percent down side by side to see how equity at day one trades against liquid cash left for reserves, moving expenses, and immediate repairs.
• Rent vs. Buy Calculator — This Rent vs Buy Calculator compares the cost of leasing against purchasing a home over a horizon you choose, such as seven years. It weighs monthly rent against PITI, maintenance, closing costs, appreciation, and equity buildup so you can see whether ownership wins on dollars in your expected tenure, not on generic always-buy advice.
• Home Equity Loan Calculator — This Home Equity Loan Calculator estimates the monthly payment on a fixed-rate second mortgage, also called a home equity loan. You enter home value, existing first mortgage balance, and the new HEL amount to see combined loan-to-value and the second lien payment alongside your first mortgage.
• HELOC Calculator — This HELOC Calculator estimates payments during the draw period and after the line enters repayment. Enter the credit line limit, amount drawn, variable rate, draw length, and repayment term to see interest-only cost now versus fully amortizing payments later when the revolving period ends.
• Mortgage Payoff Calculator — This Mortgage Payoff Calculator shows what happens when you pay more than the required amount on a fixed-rate loan. Enter your remaining balance, interest rate, standard payment, and an extra monthly amount to see a new payoff date and interest saved. It is built for homeowners who received a raise, a bonus, or a policy to retire the note before retirement.
• House Affordability Calculator — This House Affordability Calculator backs into a suggested purchase price from your gross income, monthly debts, down payment, and a debt-to-income ceiling. It combines housing payment limits with your other obligations so the result reflects lender-style ratios, not a rule of thumb based on income alone. Use it before you set a max price on search portals or ask a loan officer for a pre-approval amount.
• Mortgage Calculator — This Mortgage Calculator estimates your full monthly housing payment by combining principal and interest with property taxes and homeowners insurance. Enter the purchase price, down payment, interest rate, and loan term to see PITI in one number. Use it to sanity-check listing prices against your budget before you request a Loan Estimate.
• Amortization Calculator — This Amortization Calculator generates a month-by-month payment schedule for a fixed-rate loan. You enter the starting balance, interest rate, and term to see how each payment splits between principal and interest and how the remaining balance falls over time. Use the table to plan extra payments or to compare a fifteen-year payoff against thirty years.
• Real Estate Calculator — This Real Estate Calculator is a hub for quick property analysis: you enter purchase price, financing, expected rent, and operating costs to see cash flow, equity buildup, and common return metrics in one view. It is meant for investors and owner-occupants who want a structured first pass before they open a spreadsheet or send a deal to an agent.
• Refinance Calculator — This Refinance Calculator compares your existing loan to a proposed refinance on monthly payment, total interest, and break-even time after closing costs. Enter the current balance, rate, and remaining term alongside the new rate, term, and fees to see whether a refi pays for itself before you plan to sell or pay off the loan.
• Rent Calculator — This Rent Calculator translates monthly income into a suggested rent range using standard affordability ratios. You enter gross pay and optional debts to see what landlords and planners often treat as a sustainable rent ceiling. It helps renters set search filters before they sign a lease, not after they have already stretched for a view.
• Debt-to-Income Ratio Calculator — This Debt Ratio Calculator divides your monthly debt obligations by gross income to produce front-end and back-end debt-to-income figures. Front-end ratio counts housing costs alone; back-end ratio adds car loans, student debt, credit cards, and other recurring payments. Loan officers use these metrics in underwriting; this page lets you run the same math privately before you apply.
