This balloon loan calculator works out the regular payment on a balloon loan or equipment finance offer over the amortization period; the page then shows how to find the balloon, the balance left when the shorter term ends, by formula or spreadsheet. Sandland Credit, a small-business funding broker in Grand Junction, CO, provides it as illustrative arithmetic only, not an offer or estimate of terms.
How to use it for a balloon loan
- Amount: the amount financed, after any down payment.
- Interest rate: the note rate from the lender's offer, as an annual percentage.
- Term: enter the amortization period in months, the longer period the payments are calculated over, not the shorter period until the balloon is due.
The first result is the regular monthly payment. If you entered the full amortization period, the other two results show the total interest and total repaid as if the loan ran its full course, which is useful for comparison with a fully amortizing loan.
Turning the payment into a balloon
The balloon is the balance still owed after the payments made before maturity. With a monthly rate r (the annual note rate divided by 12, as a decimal), amount P, regular payment M and n payments made before the balloon falls due:
Balloon = P × (1 + r)n − M × [((1 + r)n − 1) ÷ r]
A spreadsheet does the same thing: list each month, add the month's interest to the balance, subtract the payment, and read the balance after the last payment before maturity. The lender's amortization schedule should show the same figure; if it does not, ask why.
A check with no interest
Purely to test the method, take a hypothetical $12,000 with zero interest, a 48-month amortization period and a balloon due after 24 payments. The calculator gives a $250 payment over 48 months. After 24 payments, $6,000 has been paid, so the balloon is $6,000. With interest, the balloon is larger than this simple split, because early payments go mostly to interest. These figures are arithmetic, not an offer.
Equipment finance with a final payment
Some equipment loans and equipment finance agreements end with a final payment sized to the equipment's expected value. Use the same steps: enter the price less any down payment, the note rate and the period the payments are based on, then work out the balance at the end of the actual term. For a lease, the end-of-term purchase amount is set by the lease itself rather than by this arithmetic. Equipment financing explains the structures.
Why your result may differ from the offer
- Fees financed into the balance, or deducted from the proceeds, change the real amount financed.
- Some lenders calculate interest daily, or use a 360-day year.
- A first payment period longer or shorter than a month shifts the schedule.
- Variable rates change the payment and the balloon over time.
Illustrative arithmetic only. Lending partners set actual rates and terms.
Using the result
Put the balloon amount and its due date next to your cash plan. If the plan is to refinance, read balloon payments, explained for the risks, and compare the offer with a fully amortizing business term loan.
