What is the Balloon Payment Calculator?
Compute the regular payment and final balloon on a partially amortized loan. To use the Balloon Payment Calculator, enter loan amount, rate, amortization, balloon due after; it returns monthly payment, balloon payment, total interest paid before balloon, and shows them instantly as you type.
How loans are priced
Every installment loan is defined by an amount, a rate and a term. The loan calculator and the payment calculator turn those into a payment and a schedule. Fees raise the real cost, which the APR calculator makes visible.
How to use the Balloon Payment Calculator
- Enter your numbers. The inputs are Loan amount ($), Rate (%), Amortization (years), Balloon due after (years). Take the rate and term from your loan offer. Fees and the rate type change the result. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Monthly payment, and the cards below show Balloon payment, Total interest paid before balloon. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Balloon Payment Calculator using the default values shown in the calculator above:
Inputs
| Loan amount ($) | 250,000 |
|---|---|
| Rate (%) | 6.5 |
| Amortization (years) | 30 |
| Balloon due after (years) | 7 |
Results
| Monthly payment | $1,580.17 |
|---|---|
| Balloon payment | $226,040.61 |
| Total interest paid before balloon | $108,774.90 |
With these inputs the calculator returns Monthly payment: $1,580.17. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Loan amount ($) from 250,000 to 300,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Monthly payment | $1,580.17 | $1,896.20 | +20% |
| Balloon payment | $226,040.61 | $271,248.73 | +20% |
| Total interest paid before balloon | $108,774.90 | $130,529.88 | +20% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
