Balloon loan—a light-sounding name for a financial product that can involve significant risk.

A balloon loan has its regular periodic payment calculated using one term (for example, 30 years), while the final payment is due earlier (for example, in 7 years).

Wikipedia defines a balloon loan or mortgage as a loan:

which does not fully amortize over the term of the note, thus leaving a balance due at maturity. The final payment is called a balloon payment because of its large size.

This Balloon Loan Calculator not only calculates the final balloon payment—it also helps you structure a loan to meet your specific needs.

Consider these common loan scenarios:

  • If you want to know what periodic payment will result in a specific final balloon amount, this calculator will calculate the regular payment.
  • If you need to set the regular payment to an agreed-upon, nontraditional amount before calculating the balloon, this calculator can do that as well.
  • If you have a budget for both the periodic payment and the balloon payment and you want to know how much you can borrow, this calculator can use your inputs to calculate the loan amount.
  • If you want to lower the periodic payment even further, you can select interest-only payments.
  • If you want the periodic payment calculated using a 30-year term while the balloon is calculated using a 7-year term, you can do that calculation too. See “Doing the Two-Step” below…

Using the Balloon Loan Calculator

Date selection via pop-up calendar

Quickly
Pick a Date

As mentioned, a balloon loan is a loan that has its regular periodic payment calculated using one term (for example, 30 years) while the last payment is due sooner (for example, in 7 years).

If you do not know the amount of the regular loan payment, then we must calculate it before we calculate the final balloon amount.

Example: Assume you are considering a mortgage for $146,500. You want the monthly payment calculated based on a 30-year loan, but you will pay the balance after 72 months.

Doing the Two-Step

Step 1: Enter:

Preparing to calculate the periodic payment.
Loan Amount?:$145,500.00
Annual Rate?:4.5000%
Balloon Due at Payment? (#):360
Periodic Payment?:$0.00
Final/Balloon Payment (can be 0)?:$0.00

When you enter “0” for both “Periodic Payment” and “Final/Balloon Payment,” you are setting up the calculator to calculate a level payment for the entire term of the loan. This means the final payment will not be a balloon payment.

Click “Calc” to see the results. $737 is the regular payment amount for a 30-year loan. (The final payment is rounded by less than $2.00, or less than $0.01 per regular payment.)

Periodic Payment?:$737.23
Final/Balloon Payment (can be 0)?:$735.27

Step 2: Now calculate the balloon payment amount. With the balloon due after six years, set the calculator as follows:

Preparing to calculate the final balloon payment.
Loan Amount?:$145,500.00
Annual Rate?:4.5000%
Balloon Due at Payment? (#):72
Periodic Payment?:$737.23
Final/Balloon Payment (can be 0)?:$0.00

Click “Calc,” and this is the balloon that will be due in the final month of the sixth year if the debtor makes payments based on an assumed 30-year term:

Final/Balloon Payment (can be 0)?:$130,433.50

If the goal is to know the balloon payment amount, then you are finished.

However, with this calculator, it is possible to do more. You can structure a loan the way you want.

Other scenarios — very flexible!

Example 2: Pick the balloon payment amount and calculate the periodic payment:
Loan Amount?:$145,500.00
Annual Rate?:4.5000%
Balloon Due at Payment? (#):72
Periodic Payment?:$0.00
Final/Balloon Payment (can be 0)?:$100,000.00
Result:
Periodic Payment?:$1,110.73
Example 3: Pick any periodic payment amount:
Loan Amount?:$145,500.00
Annual Rate?:4.5000%
Balloon Due at Payment? (#):72
Periodic Payment?:$2,000.00
Final/Balloon Payment (can be 0)?:$0.00
Result:
Final/Balloon Payment (can be 0)?:$27,541.94
Example 4: Pick your payments and see what you can borrow:
Loan Amount?:$0.00
Annual Rate?:4.5000%
Balloon Due at Payment? (#):72
Periodic Payment?:$1,000.00
Final/Balloon Payment (can be 0)?:$50,000.00
Result:
Loan Amount?:$84,794.97

A Balloon Loan with Extra Payments

The calculator’s support for extra payments is very flexible. First, you will notice that the calculator prompts you for the “Extra Payments Start?” date. Therefore, you can schedule extra payments between the regular due dates if that timing is better for your cash flow.

As mentioned elsewhere, the calculator allows for a one-time extra payment or for multiple extra payments. The multiple extra payments can be for two payments or any number of payments until the loan is paid in full. (In that case, set the number of extra payments to “Unknown.”)

When the extra payments are “off-schedule,” the calculator prepares an expanded report. The report shows the extra payment applied 100% to principal while interest continues to accrue.

Note how the interest-only payment drops from $545 to $526 after the extra payment.

This is the correct way to apply the payment—something that other online calculators do not usually handle properly, if they allow extra payments between regular payments at all.

The Interest-Only Payment Method is a Special Case

Most frequently, the periodic payments are allocated to both principal and interest. With each payment, the loan balance is reduced.

But what if the borrower wants to pay even less per period?

In that case, the lender may agree to make the balloon loan one where the borrower pays only the interest due on each payment date. Paying only the interest each period reduces the payment amount even further for the borrower.

Interest-only option selected for the regular periodic payments
Interest-only option selected for the regular periodic payments

This calculator supports interest-only payments (select the option under “Amortization Method”). If you select this option, the calculator works slightly differently.

  • First, the balloon payment will always be equal to the loan amount. Therefore, it is not possible to solve for the balloon payment.
  • Viewed in a different way, the user cannot provide a periodic payment amount. The calculator will always calculate the regular payment amount, because it is the interest due.
  • When you introduce extra payments into the interest-only cash flow, the calculator’s main window shows the amount of the first interest-only payment. After each prepaid principal amount, subsequent payments are reduced, because prepaying lowers the loan balance and therefore reduces the interest due.

Given the above, if you select interest-only, in almost all cases you will want to set both of these inputs to 0.

Periodic Payment?:$0.00
Final/Balloon Payment (can be 0)?:$0.00

Charts

Reviewing long columns of numbers can be difficult. Cash flow charts make it easier to see the relationship between principal, interest, and any extra payments.

This calculator creates three charts.

  • The annual chart compares total interest and principal paid each year.
  • The accumulated chart shows the amounts allocated to principal and interest since the start of the loan.
  • The pie chart shows the relationship between total interest and principal with calculated percentages.

Bloggers can use these charts to illustrate their analysis. Click for several export options.

Should I take out a balloon loan? There is risk.

Balloon loans have advantages. The borrower can borrow a large amount for a short period while making relatively small periodic payments.

However, the borrower should consider this loan type only if they are confident that they will have the funds available or that they will be able to refinance the loan in time to make the balloon payment when it comes due. Otherwise, the borrower will very likely default on the terms of the loan and risk damaging their credit rating.

What do you think? Is a balloon loan a useful financial product? Or are you an issuer of these loans? If so, do you have anything to add to the above?

  • Hi Karl – you were of great assistance to me on 17th April last.

    I now have a related question for you as follows;

    Run the following Calculation through the Balloon payment calculator;
    + Capital borrowed £1,895,807
    + Payable x 84 months at £21,741 per month followed by a Balloon of £405,000 as an 85th payment.
    + Loan drawdown of 23/10/20 [using European dates here].
    + First Payment on 31/10/20.
    + APR is 4.00%

    So I set Short period Option to Reduce all . . . .

    When I check Interest rate the Calculator tells me that the last Payment due has been reduced by £6,159 due to rounding to £398,843 . . . Adding back brings me to expected £405,000.

    I am completely confused by a rounding of this size – so I am assuming that I’ve done something wrong on the Amortization side of things.

    Help, please.

    • Hi Tony, I’ll have to take a look at this more closely. It may not be appropriate to have the message about rounding on this schedule since the calculator is going to calculate the balloon amount necessary to pay off the loan. The adjustment might not be due to the short period.

      Did you use the calculator to calculate any of your values (payment or balloon), or are those your inputs?

      • Hi Karl – the unknown Value when I ran the calculation initially was the Interest rate being charged with the Loan Amount, the Value and Volume of Loan repayments, the Balloon, Date of first and Monthly thereafter Payments all known.

        I tried playing around with other Variables but everything still came back to the same Balloon and rounding number . . . .

        Is there a way to share the Payment Profile, I’ve saved a PDF with you, if that would help . . .

        • Hi Tony, is the only thing you are questioning is the rounding amount shown on the schedule? As I think about it, I think that is somewhat of a meaningless number when there is a final balloon payment. The various calculators on this website share reports (programming code) in the interest of efficiency. The balloon payment is going to be what the balance is, plus accrued interest since the last payment. I’m not sure what the rounding amount means, in this case, since the last payment (balloon) is not equal to the prior payments. When this note appears if users are using other calculators it means the normal periodic payment is, for example, 556.75, and the final payment to pay the principal balance plus accrued interest is 555.25 which means the last payment was rounded (down) 1.50 relative to all the other payments.

          As you can see, we do not have that case when there is a balloon payment.

  • Robin Rickerson says:

    Can you help me please…???
    I need to do an amortization schedule with the following information:
    $63,750 loan amount
    Starts 2/26/2021
    Simple interest at 6%
    10 year amortization
    1st payment not due until month 24
    Balloon payment due month 60

    • Hi, you’ve given me the details, but you’ve not asked a question. Can you tell me what you’ve tried, or what’s not clear?

  • I used the calculator to create an amortization schedule with the following terms:

    Loan Amount $450,000
    Start date 8/1/21
    Rate 5.0%
    Term 10 Years (120 Months)
    Balloon Payment $50,000
    Balloon Payment Due – End of Term (Month 120)

    While I was able to print the schedule I couldn’t find where to download the Excel sheet, can you help? Thank you

  • Kevin White says:

    is this available as a WP plugin like some of your others?

  • I am trying to make a Balloon payment schedule total principle $41,000 with 28 interest payments at 8.5%. 2 Xtra principle payments due December 2020 and 2021 that are 12k each started 9/1/20 first payment 9/1/20. When I put in $12000 as payment then 2 payments it just keeps just putting in the first 12k payment on Dec 2020 but not the 2nd $12k payment on Dec 2021 throwing off the final payment and each monthly interest only payment. I tried changing it to $24k as payment but it then just puts the $24 k in the Dec 2020 area. How can I get the two $12k payments on Dec 2020 and Dec 2021. 28 total interest only payments with a final Balloon payment due on 1/1/23

    • When you entered the extra payments, did you enter 2 for Number of Extra Pmts, and set Extra Payment Frequency to annual? That should work.

      If it doesn’t please copy your inputs to a reply, and I’ll take a look. (You should be able to select the inputs and copy/paste.)

  • Hello,

    Working with the balloon calculator using extra payments, and I am wondering how
    you enter different dates that the payments were made, and also how to
    change the amounts of the extra payments. Then if I copy and paste the url to
    save what I have done, can I continue to add extra payments while keeping the ones
    already recorded?

    • If you are trying to record exact payments as they are made, then I would not use this calculator.

      Rather, please use Ultimate Financial Calculator.

      Scroll down the page for the link to the tutorials. There are 2 tutorials about balloon payments and one or two about extra payments.

      At a high level, the calculator allows the user to enter any payment amount on any date. Save their work. And later recall it. It will keep a running balance.

      • With the ultimate calculator could I do both, balloon loan with extra random payments?
        Thank you for your help

        • Yes, you can. The tutorials will show you how to do both. Once you look at them and give the steps a try, if you have questions, just ask.

  • Betty Pinkerton says:

    12 years ago my sister lent me 8400.00 to be repaid when I could, if ever. I am now able to repay her and would like to pay it back with 5% interest even though I know she doesn’t want interest. If interest was added yearly, how much would the total come to?

  • Chris Musgrove says:

    How do I calculate the following with your tool:

    Loan amount: $30,000
    Interest Rate: 7%
    Loan start date: 12/21/2018
    First payment date: 01/21/2022 and due monthly thereafter
    Term: 6 years (first 3 years is interest only)

    • The balloon calculator won’t handle the calculation due to the initial interest-only payments.

      However, the Ultimate Financial Calculator will handle the calculation.

      You might want to also see the tutorials. See #14 for initial interest-only payments. After you try it, if you have questions, just ask.

  • Erica Osborne says:

    Is there a way to do $300,000.00, Balloon 60 months, Principal only payments of $5800 until balloon due. Interest at end of balloon of 6%

    • Yes, but not with this balloon payment calculator.

      Please use the Ultimate Financial Calculator. Scroll down the page to the tutorials. There are a couple about balloon payments. And you’ll need to set a series as principal first until the balloon period.

  • Question, I’m trying to create a schedule, interest only, 5 year balloon, with an annual principal payment due on the first payment beginning of years 2-5. I’ve tried # of extra payments as “unknown” as also as “4”, however, the calculator does not apply the annual principal payment to year 5. Help! I love this calculator!

    • You will probably need to use this calculator.

      But I’m not sure that I understand everything. Are the payments annual? And the payments will just be applied to the principal? I need to understand these details before I can be confident that the recommended calculator will do what you need.
