First calculate the scheduled balloon balance

Use the note amount, rate, payment, amortization term, and balloon term to find the principal remaining when the balloon comes due.

Then calculate interest through the actual payoff date

If the payoff occurs after the balloon balance date, calculate the per-diem interest on the applicable balance and extend it through the target date.

Account for actual payment history when necessary

If prior payments were late, skipped, partial, or otherwise irregular, reconstruct the payment history before relying on the scheduled balloon balance.

Use the creditor or note instructions for the final amount

Fees, credits, default interest, legal expenses, and other note-specific adjustments can change the final payoff beyond the simple scheduled balance and per diem.

Worked example

If a balloon balance is $80,000 and the note accrues 8% interest on Actual/365, the per diem is about $17.53. Ten additional interest days would add about $175.34 before other adjustments.

Frequently asked questions

How do I calculate a balloon payoff?

Calculate the principal remaining at the balloon date, then add any interest and other amounts required through the actual payoff date.

Is the balloon balance the same as the payoff amount?

Not always. The payoff can include additional daily interest, fees, credits, advances, or other adjustments after the balloon balance date.

What if payments before the balloon were irregular?

Reconstruct the actual payment history before calculating the final balance because a scheduled amortization balance may no longer be accurate.

Can a balloon note use a long amortization term?

Yes. A note can calculate payments over a long amortization period while requiring the remaining principal to be paid at an earlier balloon date.
