The EMI on a loan that leaves a lump sum — a balloon — to pay at the end, the size of that lump sum, and the extra interest it costs against repaying the whole loan in EMIs.
Balloon loan EMI
A loan of $10,00,000 at 9.5% for 5 years with a 30% balloon
EMI with a balloon
- P
- the loan amount
- B
- the balloon, due with the last EMI; B × (1 + r)−n is what it is worth today at the loan rate
- r, n
- the monthly rate (annual ÷ 12 ÷ 100) and the number of EMIs. With B = 0 this is the ordinary EMI.
Worked example
A loan of $10,00,000 at 9.5% for 5 years with a 30% balloon
r = 9.5 ÷ 1200 = 0.007917; n = 60; (1 + r)−60 = 0.6230
Balloon = 30% × 10,00,000 = $3,00,000; worth 3,00,000 × 0.6230 = $1,86,915 today
EMI = (10,00,000 − 1,86,915) × 0.007917 ÷ (1 − 0.6230) = $17,076
Without a balloon the EMI is $21,002; total interest $3,24,578 against $2,60,112, $64,466 more
10 lakh at 9.5% for 5 years: bigger balloon, smaller EMI, more interest
| Balloon | Due at the end | EMI | Total interest | Extra interest |
|---|---|---|---|---|
| 0% | $0 | $21,002 | $2,60,112 | $0 |
| 20% | $2,00,000 | $18,385 | $3,03,089 | $42,978 |
| 30% | $3,00,000 | $17,076 | $3,24,578 | $64,466 |
| 40% | $4,00,000 | $15,768 | $3,46,067 | $85,955 |
| 50% | $5,00,000 | $14,459 | $3,67,556 | $1,07,444 |
How a balloon loan works — and what happens at the end
A balloon loan keeps the EMI down by leaving part of the loan unpaid until the end. The EMIs repay the loan less what the balloon is worth today, and the balloon itself falls due in one piece with the last EMI. Car finance is the commonest use, often with the balloon set near the car’s expected resale value, and some business and property loans are built the same way.
In the example a 30% balloon cuts the EMI from $21,002 to $17,076 a month, but leaves $3,00,000 to find after five years. Because that part of the loan is never paid down, interest is charged on it for the whole term, so the total interest is higher: $64,466 more here. The chart shows the difference: the balance with a balloon ends at the balloon, not at zero.
If you cannot pay the balloon. This is the risk to plan for. The balloon is a debt like any other instalment. If you cannot pay it or refinance it when it falls due, you are in default: on a secured loan the lender can repossess the car or take the property, the default is reported to credit bureaus, and fees and penal charges add to what you owe. America’s Consumer Financial Protection Bureau warns that borrowers who cannot make a balloon payment, even the last one, can lose their home. Refinancing is not guaranteed: it depends on your income, your credit record, the asset’s value then and the rates then. Selling the asset works only if it is worth at least the balloon, and cars often lose value faster than expected.
A balloon can make sense when you are sure of a lump sum by the due date. Otherwise, set money aside every month to meet it, or choose a longer ordinary loan. Compare with the car loan EMI calculator and the car loan vs cash calculator, and see the full schedule in the loan amortization calculator. This is arithmetic on the figures you enter, not financial advice.
Frequently asked questions
How is the EMI with a balloon payment calculated?
EMI = [P − B × (1 + r)^−n] × r ÷ [1 − (1 + r)^−n]. $10,00,000 at 9.5% for 5 years with a $3,00,000 balloon is $17,076 a month.
Does a balloon payment cost more interest?
Yes. The balloon part of the loan is owed for the whole term, so it earns interest all along. The example pays $64,466 more than with no balloon.
What happens if I can’t pay the balloon?
You are in default on the full amount. On a secured loan the lender can repossess the asset, and the default is reported to credit bureaus. Refinancing depends on your credit and the rates at the time, so it is not guaranteed.
Is a balloon the same as an interest-only loan?
A 100% balloon is: the EMI then covers interest only and the whole loan is due at the end. Smaller balloons repay part of the loan through the EMIs.
