What is Balloon Payment?

A balloon payment is a large lump sum due at the end of a loan or finance agreement. It reduces monthly repayments during the term but requires a significant final payment, refinancing, or asset return at maturity.

How is balloon finance calculated?

Balloon finance works by deferring a lump sum to the end of the agreement. The monthly payment is calculated on the financed amount minus the present value of the balloon, using the standard annuity formula.

The formula is:

Financed = Loan Amount - Deposit

Monthly = [Financed - Balloon / (1 + r)n] - r(1 + r)n / [(1 + r)n - 1]

Where r = monthly interest rate (annual rate - 12), n = number of months, and Balloon = the lump sum due at the end of the term.

Assumptions and caveats

  • A fixed interest rate is assumed for the full term.
  • The balloon payment is due as a single lump sum at the end of the last month.
  • Documentation fees, option-to-purchase fees, and insurance are not included.
  • Total cost of finance will be higher than a fully amortising agreement due to interest on the deferred balloon.
  • Results are indicative estimates only. Contact a provider for a formal quotation.

Worked Example

Scenario

A haulage company finances a GBP 120,000 truck over 4 years at 7% interest with a 20% balloon payment at the end.

Calculation

  1. Balloon Amount = 120,000 x 20% = GBP 24,000
  2. Financed Amount = 120,000 - 24,000 = GBP 96,000
  3. Monthly Payment on GBP 96,000 over 48 months at 7%
  4. Monthly Payment = GBP 2,299

What This Means

By deferring GBP 24,000 to the end of the term as a balloon payment, the monthly cost drops from approximately GBP 2,872 (without balloon) to GBP 2,299 - a saving of GBP 573 per month. The business must plan for the GBP 24,000 lump sum at month 48, either from cash reserves, refinancing, or selling the asset.

Frequently asked questions

A balloon payment is a larger lump sum due at the end of a finance agreement. By deferring part of the total cost to the final payment, monthly instalments during the term are reduced. Balloon payments are common in vehicle and equipment finance.

Balloon finance lowers monthly costs, improving short-term cash flow. It suits businesses that expect to refinance, sell the asset, or have a lump sum available at the end of the term. It can also match payments to an asset's useful life or expected income.

If you cannot pay the balloon at the end of the term, options typically include refinancing the balloon amount into a new agreement, selling the asset to cover the balance, or negotiating an extension with the lender. Failing to pay may result in the asset being repossessed.

A larger balloon payment reduces monthly instalments because less of the total amount is amortised over the term. However, the total cost of finance (including the balloon) will generally be higher due to interest accruing on the deferred balance.
