What a balloon payment actually costs you

A balloon — sometimes called a residual — is a lump sum left owing at the end of a finance term. Instead of paying the asset down to zero across the term, you pay it down to an agreed figure and settle the rest in one payment.

The appeal is obvious: a larger balloon means a smaller monthly repayment, which protects cash flow while the asset beds in. The cost is equally plain. Interest is charged on the outstanding balance, and a balance that stays high for longer attracts more of it. The same asset financed with a large balloon costs more over its life than one paid down evenly.

The second cost is the decision at the end. When the balloon falls due you either pay it out, refinance it, or sell the asset and settle from the proceeds. That last option only works if the asset is still worth more than the balloon — so a balloon set above what the asset will realistically be worth leaves you owing money on something you no longer have.

Used well, a balloon matches the repayment to how the asset earns: lighter while you are building the work, settled once it has paid for itself. Used badly, it is a way of making an unaffordable asset look affordable for a few years.

The question worth asking is not “what is the lowest repayment” but “what will this be worth when the balloon is due, and what will I do about it then”.
