5 Year Balloon Mortgage Calculator: What You Still Owe After 60 Payments

The 5 year balloon mortgage calculator above has two term fields, and a five-year balloon needs both. Amortized Over sets the schedule the monthly payment is computed from — choose 15, 20, 25 or 30 years to match your note (10 and 40 are also offered). Balloon Due After (years) is the maturity: type 5. It opens at 7, the default used on our balloon mortgage amortization calculator, so changing that single box is the step people miss. The field accepts half-years, so a 66-month note is 5.5.

Leave the interest-only box unchecked unless your note says no principal is due before maturity. With it checked, a $400,000 loan at 7.40% costs $2,466.67 a month and the full $400,000 is still owed in month 60 — there is no amortization to calculate.

One display detail is worth understanding before you compare the result with a lender's figure. The calculator treats payment 60 itself as the balloon. It shows 59 regular payments and then a “balloon payment due” equal to the principal remaining before that last payment, which it says is paid together with that month's interest. Many notes describe the same event differently: 60 regular payments, then the leftover balance. The cash is identical either way. On the $400,000, 30-year, 7.40% example:

• Calculator view: $378,527.21 of principal plus $2,334.25 of month-60 interest = $380,861.46 due in month 60.
• Note view: the regular $2,769.52 payment plus the $378,091.94 balance left after it = $380,861.46.

So if your payoff letter shows a number a few hundred dollars away from the calculator's balloon line, check which convention it uses before assuming one of them is wrong. The tables on this page use the note view — the balance remaining after 60 regular payments — because that is how most people phrase the question. The monthly payment itself comes from the standard formula M = P · r(1+r)ⁿ / ((1+r)ⁿ − 1), with n equal to the amortization months, not 60; our page on how mortgage amortization is calculated walks through it step by step.

The amortization period is the lever that decides how big the balloon is. A shorter schedule raises the monthly payment and pushes more of each payment into principal, so less is left at month 60. The rate matters too, but in the opposite direction from what people expect: a higher rate leaves a larger balance, because a bigger share of each early payment is interest.

Inputs: $400,000 loan, fixed rate, 60 regular monthly payments, no extra principal. 6.71% and 7.40% are Freddie Mac's 15- and 30-year PMMS averages for the week of October 15, 2026; 8.40% is the 30-year average plus one point. Computed by this site's amortization formula on 2026-10-19.

Three things stand out. First, even the most aggressive structure here, a 15-year amortization, leaves more than three-quarters of the loan unpaid after five years. Second, going from 30 to 25 years costs $160.48 more a month at 7.40% and shrinks the balloon by $11,608.70; going all the way to 15 years costs $915.84 more a month and shrinks it by $66,250.70. Third, the share still owed barely moves with the rate — between 6.71% and 8.40% the 30-year column only shifts from 93.8% to 95.4% — so the rate mainly changes what you pay along the way, while the amortization period decides what remains.

A 5-year term with 25-year amortization, a common way commercial and small-portfolio lenders write these notes, sits in the third row of each block. If you want to see every month rather than the endpoint, the amortization schedule with balloon payment lays out the row-by-row mechanics, and the CSV download under the calculator exports your own 60 rows.

Five years is the shortest common balloon term, and the CFPB's explainer on balloon payments (read October 2026) puts balloon-loan terms generally between 5 and 10 years. Holding the loan and rate fixed and moving only the due date shows what the extra years buy.

Inputs: $400,000 at 7.40% fixed. Rows without an asterisk are amortized over 30 years; rows marked * over 25 years. Computed by this site's amortization formula on 2026-10-19.

On the 30-year schedule, two extra years (seven instead of five) retire another $11,291 of principal, and five extra years (ten instead of five) retire another $31,681. That is the same front-loaded interest pattern that governs any long schedule, visible in the 30-year mortgage amortization schedule: in the first decade, most of every payment goes to interest. The case for a longer balloon term is therefore less about the balloon getting smaller and more about time — time for income to rise, for a sale to happen on your schedule, or for rates to come down before you must refinance. A five-year note gives you the least of that time and leaves the most behind.

Note how close two cells are: a 5-year balloon on 25-year amortization ($366,483.24) leaves almost exactly what a 7-year balloon on 30-year amortization does ($366,800.87). If a lender offers you either structure, the decision turns on whether you would rather pay $160.48 more each month or have two more years before the due date.

The plan behind most five-year balloons is to refinance before the due date. The CFPB's balloon-payment page says you may be able to do that, but warns that if your property's value falls or your financial condition declines, you might not be able to — and that if you cannot make the balloon payment you could face foreclosure. There is a third risk the balloon creates that a fully amortizing fixed loan does not: the rate on the replacement loan is set in year five, not today.

Take the $378,091.94 left on the $400,000, 30-year, 7.40% example and refinance it at different rates. The 25-year column keeps the original payoff horizon; the 30-year column restarts the clock.

Inputs: $378,091.94 balance (owed after 60 payments on $400,000 at 7.40%, 30-year amortization), new fixed-rate loan, no closing costs added to the balance. Computed by this site's amortization formula on 2026-10-19.

Each point of rate on the replacement loan adds about $250 to $266 a month on the 25-year schedule. A three-point rise turns a $2,769.52 payment into $3,542.91 — $9,280.68 a year more — and stretching back to 30 years recovers only about $113 of that. For a sense of how far the reference rate can travel in twelve months, Freddie Mac's survey shows the 30-year average at 6.27% a year before the October 15, 2026 reading of 7.40%, a rise of 1.13 points. Closing costs on the new loan are not in the table; if you finance them, add them to the balance and rerun the numbers in our refinance amortization calculator.

A practical stress test: run the 5 year balloon mortgage calculator with your note, then take the balance due and price it at your rate plus two or three points. If that payment would not fit your budget, the balloon is not just a future refinance — it is a bet on rates, and the earlier you plan an exit (extra principal, a sale timeline, or savings earmarked for the gap) the more options you have.

For loans to consumers secured by a dwelling, the federal ability-to-repay rule in Regulation Z, 12 CFR 1026.43 (eCFR, read October 2026) treats balloon payments specifically. Three provisions bear directly on a five-year note:

• Qualified Mortgage status. Under §1026.43(e)(2)(i)(C), a general qualified mortgage cannot have regular periodic payments that result in a balloon payment, except as provided in §1026.43(f). The CFPB's consumer page states the same point plainly: balloon payments are not allowed in loans deemed a Qualified Mortgage, with some limited exceptions.
• The balloon exception and its five-year floor. §1026.43(f) lets certain creditors that meet the requirements in §1026.35(b)(2)(iii) make balloon-payment qualified mortgages. Among the conditions: scheduled payments that are substantially equal and calculated on an amortization period that does not exceed 30 years, an interest rate that does not increase over the term, and a loan term of five years or longer. A five-year balloon is the shortest term that clause permits, and a 40-year amortization falls outside it.
• Which payment the creditor must underwrite. §1026.43(c)(5)(ii)(A) says that for a loan with a balloon payment, the creditor considers the maximum payment scheduled during the first five years after the first regular payment is due if the loan is not a higher-priced covered transaction, or the maximum payment in the schedule including the balloon if it is higher-priced. For a balloon-payment qualified mortgage under §1026.43(f), the creditor instead verifies that you can make the scheduled payments excluding the balloon.

Read together, those rules mean a residential five-year balloon from a creditor that qualifies under §1026.43(f) can be approved on the strength of the regular payment alone — nothing in that underwriting tests whether you can pay or refinance the $378,091.94. That part of the analysis is yours, which is what the refinance table above is for. Which provisions apply to a particular loan depends on the creditor and the loan's pricing, so ask the lender whether your note is a qualified mortgage and under which paragraph. The scope paragraph, §1026.43(a), limits the rule to consumer credit secured by a dwelling; a business-purpose commercial loan sits outside it, although the amortization arithmetic in every table here is the same.

Finally, compare the CFPB's description with the numbers: it says a balloon payment is generally more than two times the loan's average monthly payment. On a 30/5 note the final balance is about 136 times the $2,769.52 monthly payment, and even on 15-year amortization it is about 85 times. That ratio, more than the rate, is the size of the decision.
