What is Balloon Payment?
The Balloon Payment calculation tells you your balloon payment due from a few simple inputs. The figure you are solving for here is the balloon payment due, expressed in INR.
The Balloon Payment formula
The core formula is:
Balloon payment due = Loan amount × (1 + Annual interest rate ÷ 1200)^(Balloon due after × 12) - (Loan amount × (Annual interest rate ÷ 1200) × (1 + Annual interest rate ÷ 1200)^(Amortisation term × 12) ÷ ((1 + Annual interest rate ÷ 1200)^(Amortisation term × 12) - 1)) × ((1 + Annual interest rate ÷ 1200)^(Balloon due after × 12) - 1) ÷ (Annual interest rate ÷ 1200)Here is what each input means:
- Loan amount — a money amount. Example: ₹2,00,000.
- Annual interest rate — a percentage, such as an annual rate. Example: 6%.
- Amortisation term — a value measured in years. Example: 30 years.
- Balloon due after — a value measured in years. Example: 5 years.
How to calculate it step by step
- Write down the loan amount (for example, ₹2,00,000).
- Write down the annual interest rate (for example, 6%).
- Write down the amortisation term (for example, 30 years).
- Write down the balloon due after (for example, 5 years).
- Apply the formula above to get your balloon payment due.
- Double-check the result with the Balloon Payment Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Loan amount | ₹2,00,000 |
| Annual interest rate | 6% |
| Amortisation term | 30 years |
| Balloon due after | 5 years |
| Balloon payment due | ₹1,86,108.71 |
| Monthly payment | ₹1,199.10 |
With loan amount of ₹2,00,000, annual interest rate of 6%, amortisation term of 30 years and balloon due after of 5 years, the balloon payment due works out to ₹1,86,108.71.
Example 2
With loan amount of ₹4,00,000, annual interest rate of 6%, amortisation term of 30 years and balloon due after of 5 years, the balloon payment due works out to ₹3,72,217.43.
| Result | Value |
|---|---|
| Balloon payment due | ₹3,72,217.43 |
| Monthly payment | ₹2,398.20 |
Example 3
With loan amount of ₹1,00,000, annual interest rate of 6%, amortisation term of 30 years and balloon due after of 5 years, the balloon payment due works out to ₹93,054.36.
| Result | Value |
|---|---|
| Balloon payment due | ₹93,054.36 |
| Monthly payment | ₹599.55 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
