What is Balloon Payment and how is it calculated?
Balloon payment loans are a form of loan that monthly payments are lower than regular repayments because they do not cut off the full principal, but have a large amount of money called a "balloon" outstanding and payable at the end of the contract.
Balloon Payment Formula
The monthly rate is calculated from the PMT formula adjusted to the current value of the balloon:
Balloon = balloon ÷ (1+r)ⁿ
The principal = the loan - the present value of the balloon.
The amount of the loan = principal × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
Total interest = (payment × number of payments + balloon) − loan
Calculation example
Loan 1,000,000 baht Interest 5.5% per year Repayment 60 per month Balloon sum 300,000 baht:
Balloon instalment: about 12,500 baht/month
Normal massage (without balloon): approximately 19,100 baht/month
Savings in instalment: approximately 6,600 baht/month
But the total interest is higher than normal because the principal decreases slower.
Considerations Before Choosing Balloon Payment
There must be a plan to pay off the balloon-- from savings, property sales, or refinancing.
Total interest is higher than the normal rate.
Ideal for those who need a high monthly cash flow in the first place.
Check the bank's terms for refinancing balloon advances.
