Balloon Loan Calculator

Balloon Loan Calculator

Balloon loans feature lower initial payments with a large lump sum due at the end of the term.

What This Calculator Shows

• Monthly Payment: Your expected payment amount based on loan terms
• Total Interest: The cost of borrowing over the loan lifetime
• Amortization Schedule: How payments split between principal and interest
• Payment Breakdown: Visual representation of your loan costs

How to Calculate

1. Enter your loan amount 2. Input the interest rate (APR) 3. Select the loan term 4. Review your payment details and total costs

Key Considerations for Balloon Loan

• Compare offers from multiple lenders before committing
• Understand all fees including origination, closing costs, and prepayment penalties
• Consider how rate changes might affect your payments (for variable rates)
• Factor in your overall financial goals and debt-to-income ratio

A balloon loan amortises on a long schedule — usually 30 years — but the full remaining balance falls due at the end of a short term, typically five or seven years.

	Balloon (30-yr amortisation, 7-yr term)	Standard 30-year
Monthly payment	$1,580	$1,580
Balance after 7 years	$225,000 due at once	$225,000, keeps amortising

The payment is identical. What differs is that year seven arrives with a quarter of a million dollars due, and you have three options: refinance, sell, or default. Two of those depend on conditions you do not control — a rate spike or a price fall in year seven turns a manageable loan into a forced sale.

Balloons make sense when you have a specific, near-certain exit. They are not a way to afford a house you otherwise could not.

The Numbers This Page Opens With

The calculator above starts at $250,000 over 7 years at 6.5%, which is representative for this product:

Monthly payment	$3,712
Total repaid	$311,838
Total interest	$61,838
Interest as a share of principal	25%

Change any input above and every figure recalculates. The amortisation formula behind it:

`` M = P × [ r(1+r)^n ] / [ (1+r)^n − 1 ]

P = principal, r = monthly rate (annual ÷ 12), n = number of payments ``

Before You Sign

• Compare APR, not the rate. APR includes origination and points; the rate does not.
• Ask about prepayment penalties. They turn a plan to pay early into a fee.
• Rate-shop inside 14 days. Credit scoring models treat multiple mortgage or auto

enquiries in that window as one enquiry.

• Check whether the payment includes escrow. A mortgage quote without taxes and insurance

understates the real monthly cost by hundreds.

Where the Money Goes

On $250,000 at 6.5% over 7 years, paying $3,712 a month:

Point	Principal repaid	Interest paid	Balance
Year 1	$19,227	$10,472	$230,773
Year 2	$52,299	$25,661	$197,701
Year 4	$110,880	$45,039	$139,120
Year 5	$176,499	$57,380	$73,501
Year 7	$250,000	$61,838	$0

Early payments are mostly interest. That is not a fee structure — it is arithmetic: interest accrues on the outstanding balance, which starts at its largest. It is also why an extra payment made early saves far more than the same payment made late.

What a Rate Change Costs

Rate	Monthly	vs 6.5%	Total repaid
5.50%	$3,593	-$120	$301,771
6.00%	$3,652	-$60	$306,780
6.50%	$3,712	—	$311,838
7.00%	$3,773	+$61	$316,946
7.50%	$3,835	+$122	$322,104

Half a percentage point moves the monthly payment by $61 and the total by $5,108. Shopping three lenders usually beats any amount of negotiating on price.
