Calculator guide
Estimate payments and the balance due at the balloon date. Use the explicitly labelled inputs below; rates, dimensions, and costs are assumptions, not live quotes.
Formula or method
Calculate the regular payment over the amortization term. Balance after k payments = P(1+r)^k − M((1+r)^k−1)÷r; at zero interest use P − M×k.
How to use this calculator
- Set Loan Amount. The interface starts with 250000; replace it with the value for your scenario.
- Set Interest Rate (%). The interface starts with 6; replace it with the value for your scenario.
- Set Amortization Term (years). The interface starts with 30; replace it with the value for your scenario.
- Set Balloon Due In (years). The interface starts with 7; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
Enter Loan Amount = 250000; Interest Rate = 6 %; Amortization Term = 30 years; Balloon Due In = 7 years. With those assumptions, the calculator gives Monthly Payment: $1,498.88; Balloon Payment: $224,098.46; Payments Before Balloon: $125,905.61. These outputs are calculated from the same implementation as the interactive tool.
Understanding the result
In this example, Monthly Payment is $1,498.88. Balloon Payment is $224,098.46. Estimates exclude charges and rules not represented by the inputs. Rates and prices are assumptions; results are not a quote or guaranteed return.
Limitations and assumptions
- Estimates exclude charges and rules not represented by the inputs. Rates and prices are assumptions; results are not a quote or guaranteed return.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
