Balloon Payment

Balloon Payment

The lump sum due at the end of a balloon loan: the balance remaining after n years of regular payments that were sized for a longer amortization.

When to use: Use for balloon mortgages, commercial loans amortized over 25 or 30 years but due in 5, 7 or 10, and any loan where regular payments stop before the balance is retired.

Formula

Bnm=PV(1+k/m)nmPMT×(1+k/m)nm1k/mB_{nm} = PV(1+k/m)^{nm} - PMT \times \frac{(1+k/m)^{nm} - 1}{k/m}

Real-Life Examples

Example 1: 7-Year Balloon on a 30-Year Schedule

A $500,000 loan at 6% with payments of $2,997.75, sized for 30-year amortization but due after 7 years. Balloon?

Given

PV = $500,000.00PMT = $2,997.75k = 6.0000%m = 12.00n = 7.00 years

Step-by-Step

1.Payments before the balloon = 7 × 12 = 84
2.Balance after 84 payments on the amortizing schedule
3.Balloon ≈ $448,197.20
Result:$448,197.20

After seven years of $2,998 payments, almost 90% of the loan is still owed in one lump. Balloon structures depend on refinancing or selling before the due date.

Example 2: 5-Year Balloon

A $200,000 loan at 5% with $1,073.64 payments (30-year amortization) due in 5 years.

Given

PV = $200,000.00PMT = $1,073.64k = 5.0000%m = 12.00n = 5.00 years

Step-by-Step

1.Payments before the balloon = 5 × 12 = 60
2.Balance after 60 payments
3.Balloon ≈ $183,657.68
Result:$183,657.68

Only $16,342 of principal has been repaid in five years. The balloon is nearly the whole original loan.

Frequently Asked Questions

Yes. A balloon is simply the remaining balance at the moment the regular payments stop, so this formula is the remaining-balance formula evaluated at n years.

Usually from a longer amortization schedule than the loan's actual term, which keeps the payment low and leaves a large balance to be paid or refinanced at maturity.
