Real Estate Calculator
Payments, cash flow, and the next move.
A real estate financial calculator for mortgage payments, buying power, rental cash flow, and selling one house to buy the next.
A real estate financial calculator
If you’re selling and buying in the same move, start with The Real Number. The tools below answer a payment, a budget, or a rental cash-flow question. Change the example values and see what a different rate or timeline does.
Estimates only, not a loan quote and not tax advice. Defaults are examples, not current rate quotes. Confirm rates, fees, and loan terms with your lender. What an investor can deduct is a separate question, covered in the real estate tax deductions guide. Software I send landlords to is on investor tools.

Assumptions & what’s included
Fixed-rate loans with a known remaining term. Payment break-even divides fees by monthly payment savings; it does not account for equity, investment returns or cash-out benefits. Total cost savings compare all remaining payments and fees, subtracting cash received. Extending the term may increase total cost.

Annual MIP here uses the initial base loan; actual premiums decline with the balance. Defaults are illustrative. No eligibility or loan-limit determination.

Change any input to update your estimate.
Assumptions & what’s included

Estimate a rent budget from income and existing debt.
Your estimate

Change any input to update your estimate.
Assumptions & what’s included
Uses the smaller of the rent-to-income limit and the total debt limit less existing debt. Income is before tax. These are adjustable budgeting assumptions; allow room for utilities, savings and living costs.
11Rent vs. buy
Compare a stay of your choosing, including equity and opportunity costs.
Your estimate
- Buying: net cost over your stay
- Renting: net cost over your stay
- Buying advantage (negative favors renting)
- Projected net sale equity
Change any input to update your estimate.
Assumptions & what’s included
Compares outflows grown at your investment-return assumption, less sale equity or the returned rental deposit at the end of your stay. A negative net cost means the projected terminal asset exceeds those outflows. Rent and costs rise annually; home value compounds annually. Excludes tax deductions, tax benefits, investment taxes and moving costs. Growth assumptions are uncertain; try falling prices too.
Frequently asked questions
What is a real estate calculator?
A real estate calculator estimates the money in a property decision before you write an offer. On this page that means a mortgage payment, a price you can carry, the cash to close, and the cash flow on a rental. The figures start as examples. They are not a loan quote.
What does a real estate financial calculator estimate?
It estimates the payment, the price, the cash to close, and the year-one cash flow from the numbers you type in. The Real Number is the one I use when a sale and a purchase are the same move. Change the rate or the timeline and read the new result. Confirm the terms with your lender.
Are these real estate calculator results tax advice?
No. The rental calculator leaves out depreciation, a 1031 exchange, and the tax on a sale. Those questions belong with your CPA. I am a broker, not your tax preparer. The deductions I walk through with investors are on the tax guide linked above.
