- Solve for
- Monthly payment
- Financed balance
- $18,000
- Interest rate (APR)
- 9%
- Loan term
- 4 years
- Extra monthly payment
- $0
$18,000 at 9.00% over 4 years
- Loan amount$18,000
- Monthly payment$447.93
- Total interest$3,501
How the monthly payment changes with financed balance
Holding the other inputs at the example above, here is how the result moves as financed balance changes.
| Financed balance | Monthly payment | Loan amount |
|---|---|---|
| $9,000 | $223.97 | $9,000 |
| $18,000 | $447.93 | $18,000 |
| $27,000 | $671.90 | $27,000 |
| $36,000 | $895.86 | $36,000 |
The math behind it
This calculator treats a deferred-payment sale as an amortizing obligation. It takes the financed balance, the interest rate, and the remaining term, and computes the fixed monthly payment that pays the balance to zero, along with the total interest and the payoff schedule. You can also solve for the balance a given payment supports.
Assumptions & limits
- The obligation is modeled as a standard fixed-rate, fully amortizing loan with no balloon.
- The rate entered is treated as the periodic interest rate applied to the outstanding balance.
- It computes the payment and remaining balance on the buyer's obligation; it does not calculate the taxable gain or loss on an actual repossession.
- Fees, late charges, and repossession costs are not included.
Common questions
What does this calculator actually compute?
It sizes the payment and payoff on a deferred-payment installment obligation — the balance financed, the interest rate, and the term determine a fixed monthly payment and the remaining balance over time. It is the amortization side of the transaction, not the tax accounting of a repossession.
How is a deferred-payment sale different from a standard installment sale?
In an installment sale the buyer pays in periodic amounts over time, with each payment part principal and part interest. A deferred-payment arrangement pushes the payment obligations to a later schedule. For the payment math here both are treated as amortizing balances; the meaningful differences are in timing and in how gain is reported for tax.
Where do I figure the tax gain or loss if I repossess the property?
That is a separate calculation. Broadly, gain or loss on repossessing personal property is the property's fair market value minus your remaining basis in the buyer's obligation, less repossession costs — the rules are in IRS Publication 537. This tool handles the loan-payment side; consult the publication or a tax professional for the gain-or-loss figure.
