The Quick Version

This free owner financing calculator shows your monthly payment instantly — enter sale price, down payment, interest rate, and term.

It also calculates total interest and total of payments over the full loan — so you can see the real cost of the deal before you make an offer.

Balloon payments are supported — toggle one on to see the remaining balance due on the balloon date, a feature most mortgage calculators skip.

Owner-financed payments are amortized like any loan — the financed amount (price minus down payment) spread over the term at the agreed rate.

How this calculator works

Your monthly payment is the financed amount (sale price minus down payment) amortized over the loan term at the interest rate you both agree on. If the deal has a balloon, your monthly payments are still calculated over the full term, but the entire remaining balance comes due on the balloon date — so you'll refinance or pay it off then.

The owner financing payment formula

Owner-financed payments use the same amortization math as any mortgage. The monthly payment is:

M = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]

Where P is the principal (amount financed), r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments (years × 12). The calculator above does this instantly — and adds the balloon balance if you enable it.

What the calculator doesn't include

This tool estimates principal and interest only — the core of your monthly payment. A complete deal also involves:

Property taxes and insurance — often paid by the buyer, sometimes collected in escrow.
Closing costs — title work, recording fees, and attorney fees.
Any late fees or servicing fees defined in your note.

Always confirm your exact numbers and structure with a real estate attorney and a CPA before signing.

Calculator Questions

Owner Financing Calculator: FAQ

How is an owner financing payment calculated?

It's calculated like any amortizing loan. The financed amount (sale price minus down payment) is amortized over the loan term at the agreed interest rate, using the standard formula M = P·r·(1+r)ⁿ ÷ ((1+r)ⁿ − 1). If there's a balloon, payments are based on the full amortization but the remaining balance is due on the balloon date.

What is a balloon payment in owner financing?

A large lump sum of the remaining balance that becomes due after a set number of years, even though monthly payments were calculated over a longer schedule. For example, payments amortized over 30 years but with a balloon making the full balance due in 5 — at which point the buyer usually refinances or pays it off.

What is a typical interest rate for owner financing?

Rates are negotiated directly and are often somewhat higher than bank mortgage rates, since the seller takes on the lending risk. They vary widely by deal, market, down payment, and creditworthiness. Both sides should confirm the rate complies with state usury limits and IRS minimum-interest rules.

How much down payment is typical?

Typically 10–20%, though fully negotiable. A larger down payment lowers the buyer's monthly payment and total interest and gives the seller more security — so it benefits both sides in different ways. Try different values above to see the effect.
