The highlighted final row is the balloon: the remaining balance owed in full at the end of the balloon term. Most borrowers refinance, sell, or repay in cash at that point.
How to use the balloon payment calculator
Four quick steps show both halves of a balloon loan — the monthly payment you’d make until the balloon date, and the lump sum that falls due when you get there.
Enter the loan
Price, down payment, and interest rate to set the amount borrowed.
Set both terms
The amortization schedule the payment is based on, and the year the balloon falls due.
Pick the structure
Amortizing retires some principal; interest-only retires none, so the balloon is the full loan.
Read both numbers
Monthly payment, the balloon due, the schedule up to it, and a downloadable PDF.
The balloon is not optional. At the end of the balloon term the entire remaining balance is due in a single payment — on the default figures, that’s about 361,665 owed at once in year 7. You must refinance, sell, or pay it in cash, and none of those is guaranteed to be available on acceptable terms. Have the exit planned before you sign, not when the date arrives.
How a balloon payment is calculated
A balloon loan runs on two different clocks. The payment is set by a long amortization schedule, but the loan actually ends on a much shorter one — and the balance left over on that date is the balloon.
Worked example — 500,000 home, 20% down, 6.50%, amortized over 30 years, balloon at year 7
Loan amount: 500,000 − 100,000 = 400,000
Payment on the 30-year schedule: ≈ 2,528.27 a month
Paid over seven years: ≈ 212,375
Of which interest: ≈ 174,040 · principal retired: ≈ 38,335
≈ a 361,665 balloon due in year 7 — after seven years and 212,375 paid, you have retired under 10% of the loan.
Balloon payment charts
Handy lookups for the questions people ask most — how big the balloon gets, what actually lowers the payment, and what it takes to refinance when the date arrives. Figures use a 400,000 loan at 6.50% amortized over 30 years with a balloon at year 7, unless noted.
| Balloon due | Balloon owed | Principal retired | Interest paid | Total paid first |
|---|---|---|---|---|
| Year 3 | 385,669 | 14,331 | 76,687 | 91,018 |
| Year 5 | 374,444 | 25,556 | 126,140 | 151,696 |
| Year 7 | 361,665 | 38,335 | 174,040 | 212,375 |
| Year 10 | 339,105 | 60,895 | 242,497 | 303,393 |
| Year 15 | 290,237 | 109,763 | 345,326 | 455,089 |
The balloon shrinks slowly because early payments are almost entirely interest. Even after fifteen years and 455,089 paid, you would still owe 290,237 — about 73% of what you originally borrowed.
| Structure | Monthly P&I | vs. 30-yr fixed | Balloon at year 7 |
|---|---|---|---|
| 15-yr amortization | 3,484.43 | +956.16 | 260,299 |
| 20-yr amortization | 2,982.29 | +454.02 | 313,533 |
| 30-yr amortization | 2,528.27 | — | 361,665 |
| 40-yr amortization | 2,341.83 | −186.44 | 381,431 |
| Interest-only | 2,166.67 | −361.60 | 400,000 |
Read this row carefully: an amortizing balloon on a 30-year schedule costs exactly the same as an ordinary 30-year fixed mortgage at the same rate. The balloon buys no payment relief by itself — relief comes only from a longer schedule, an interest-only structure, or a lower rate on the balloon product. Every dollar of payment saved reappears in a bigger balloon.
| Rate | Monthly P&I | Interest paid by year 7 | Balloon owed |
|---|---|---|---|
| 5.50% | 2,271.16 | 146,041 | 355,264 |
| 6.00% | 2,398.20 | 160,007 | 358,558 |
| 6.50% | 2,528.27 | 174,040 | 361,665 |
| 7.00% | 2,661.21 | 188,131 | 364,590 |
| 7.50% | 2,796.86 | 202,272 | 367,336 |
A higher rate raises the payment and leaves a larger balloon, because more of each payment is consumed by interest. Two points of rate moves the balloon by about 12,000 but the seven-year interest bill by more than 56,000.
| Rate at the balloon date | Over the remaining 23 years | On a fresh 30-year loan | Change vs. today’s payment |
|---|---|---|---|
| 5.50% | 2,312.08 | 2,053.42 | −216 to −475 |
| 6.50% | 2,528.27 | 2,285.97 | 0 to −242 |
| 7.50% | 2,753.68 | 2,528.81 | +225 to 0 |
| 8.50% | 2,987.67 | 2,780.89 | +459 to +253 |
If rates are unchanged, refinancing over the remaining 23 years reproduces your existing payment almost exactly. The risk is entirely one-sided in the sense that matters: you cannot know the rate seven years out, and a two-point rise costs roughly 460 a month. Closing costs on the new loan are extra.
| Loan-to-value required | Home must appraise at | Versus the 500,000 you paid |
|---|---|---|
| 80% (best terms) | 452,100 | A drop of about 10% blocks it |
| 90% | 401,900 | A drop of about 20% blocks it |
| 95% (mortgage insurance likely) | 380,700 | A drop of about 24% blocks it |
This is the second half of the refinance risk and the one people miss. Because the balloon structure retires so little principal, your ability to refinance depends heavily on the property holding its value — and on your income and credit still qualifying at that future date.
rates must cooperate
value must cover it
cash must exist
Every balloon loan ends one of three ways, and each depends on something you don’t control — rates, property values, or your own liquidity years from now.
- Refinance — needs acceptable rates, enough equity, and qualifying income and credit.
- Sell — needs a sale price above the balance plus selling costs, on your timetable.
- Pay in cash — needs the full balance available, which is rare on a residential balloon.
Everything the calculator works out
One loan and two terms gives you both sides of the structure — what you pay along the way, and what lands on the balloon date.
Key figures behind balloon loans
Built for loans with a planned exit
Balloon structures work when you already know how the loan ends. The calculator prices that exit so you can check it’s realistic before committing.
Financing a commercial or investment property where five- and seven-year balloons with 25- or 30-year amortization are the market standard.
- Size the balloon against projected value
- Model a higher refinance rate
- Check any prepayment or defeasance terms
Buying with owner financing that bridges a few years until conventional financing becomes possible, and needs to know the size of the bridge.
- Get the balloon date in writing
- Confirm what happens if you can’t refinance
- Have a real estate attorney review it
Expects to sell or relocate before the balloon date, and wants to check the sale would clear the balance with room to spare.
- Compare the balloon to a conservative sale price
- Subtract selling costs from proceeds
- Ask what happens if plans slip
7 tips before taking a balloon loan
The structure is manageable with an exit you control, and dangerous without one. These checks separate the two.
Balloon payment calculator FAQ
The structure, availability, refinancing, and risk questions people ask most about balloon loans.
A balloon payment is the entire remaining loan balance, due as a single lump sum at the end of a shorter balloon term. The payments you make before that date are calculated as if the loan ran much longer, so they barely dent the balance.
On a 400,000 loan at 6.5% amortized over 30 years with a balloon at year 7, you would pay about 2,528 a month and still owe roughly 361,665 on the balloon date. Only about 38,335 of principal is retired in those seven years.
The payment is worked out from the long amortization schedule, then the loan is amortized forward only as far as the balloon date. Whatever balance remains at that point is the balloon.
With an interest-only structure the calculation is simpler still: no principal is repaid at all, so the balloon equals the full original loan amount. On a 400,000 loan that means paying about 2,167 a month for seven years and still owing the entire 400,000.
Not automatically, and this is the most misunderstood part. An amortizing balloon loan with a 30-year schedule has exactly the same payment as an ordinary 30-year fixed mortgage at the same rate — about 2,528 on a 400,000 loan at 6.5%. The balloon buys no payment relief at all.
Lower payments come from three specific things: an interest-only structure, which drops the payment to about 2,167; an amortization schedule longer than 30 years, where a 40-year schedule gives about 2,342; or a lower interest rate offered on the balloon product itself. If none of those apply, you are taking the balloon risk for nothing.
There are three normal exits: refinance the remaining balance into a new loan, sell the property and pay the balance from the proceeds, or repay it in cash. Some lenders will also discuss an extension or modification, but none are obliged to.
If none of those work, the loan goes into default and the lender can foreclose. This is why the balloon date matters so much: start arranging the exit six to twelve months ahead rather than in the final weeks, and contact your servicer early if you expect difficulty. A HUD-approved housing counselor can help at no cost.
They are heavily restricted on owner-occupied homes. Federal ability-to-repay and Qualified Mortgage rules generally exclude balloon features, with a narrow exception for small creditors operating predominantly in rural or underserved areas, and high-cost mortgages generally cannot carry them at all.
Balloon structures remain common outside consumer home lending: commercial real estate, investment property, land contracts, seller financing, construction and bridge loans, and some business and equipment lending. Confirm what is permitted for your loan type and state with a licensed lender or attorney.
An amortizing balloon retires some principal along the way, so the balloon is smaller than the original loan. An interest-only balloon retires none, so the balloon equals the full amount borrowed.
On a 400,000 loan at 6.5% over seven years, the amortizing version costs about 2,528 a month and leaves a 361,665 balloon, while the interest-only version costs about 2,167 and leaves the whole 400,000. The interest-only route saves about 362 a month and costs you about 38,000 of equity you would otherwise have built.
It depends entirely on rates at the balloon date, which nobody can predict. Refinancing a 361,665 balloon over the 23 years remaining costs about 2,528 a month if rates are still 6.5% — identical to what you were paying — but about 2,988 at 8.5%, roughly 460 a month more.
You also need enough equity to qualify. To refinance that balance at 80% loan-to-value the home must appraise at about 452,000, so on a home bought for 500,000 a value drop of around 10% could leave you unable to refinance on standard terms.
The structure fits situations where you already know the exit and it does not depend on future rates. Selling before the balloon date, replacing construction or bridge financing with permanent financing, a commercial property with a planned refinance, or seller financing that bridges a short gap are the usual cases.
It fits far less well when the plan is simply to refinance later and hope conditions allow it. That plan depends on rates, on your income and credit at the time, and on the property still appraising high enough — three things entirely outside your control.
General Estimating Notice: This calculator models a fixed-rate balloon loan using the price, down payment, rate, amortization schedule, balloon term, structure, and housing costs you enter. It assumes the rate stays fixed to the balloon date and excludes mortgage insurance, origination and closing costs, prepayment penalties, and any reset, extension, or conversion features your note may contain. A balloon loan requires the full remaining balance to be repaid, refinanced, or the property sold at the balloon date, and refinancing depends on future interest rates, property values, and your income and credit at that time — none of which can be predicted. Balloon features are restricted on most owner-occupied consumer mortgages under federal ability-to-repay rules; availability varies by loan type, lender, and state.
