1. What is a Mortgage Amortization Calculator With Balloon?

Definition: This calculator computes the amortization schedule for a loan with a balloon payment, showing how much principal and interest you pay each period until the balloon payment is due.

Purpose: It helps borrowers understand their payment schedule and the large final (balloon) payment that comes due after a specified period.

2. How Does the Calculator Work?

The calculator uses these formulas:

\[ I_k = B_{k-1} \times r \] \[ P_k = M - I_k \] \[ B_k = B_{k-1} - P_k \]

Where:

\( I_k \) — Interest portion of payment k (USD)
\( P_k \) — Principal portion of payment k (USD)
\( B_k \) — Loan balance after payment k (USD)
\( r \) — Monthly interest rate (decimal)
\( M \) — Monthly payment amount (USD)
balloon — Final balloon payment (USD)

Explanation: The calculator first determines the monthly payment as if the loan would be fully amortized, then calculates the remaining balance at the balloon term date.

3. Importance of Balloon Payment Calculation

Details: Understanding your balloon payment helps with financial planning, as you'll need to pay this large sum or refinance when it comes due.

4. Using the Calculator

Tips: Enter the loan amount, annual interest rate, full loan term (years), and when the balloon payment is due (years). All values must be > 0 and balloon term ≤ loan term.

5. Frequently Asked Questions (FAQ)

Q1: What is a balloon payment?
A: A balloon payment is a large lump sum due at the end of a loan term after a series of smaller regular payments.

Q2: Why would someone choose a balloon mortgage?
A: Balloon mortgages typically have lower monthly payments initially, which can be attractive for those expecting to sell or refinance before the balloon comes due.

Q3: How is the balloon payment calculated?
A: It's the remaining loan balance after making regular payments for the balloon term period.

Q4: What happens if I can't pay the balloon payment?
A: You may need to refinance the balloon amount, sell the property, or negotiate with the lender - failure to pay may result in foreclosure.

Q5: Are balloon payments risky?
A: They can be, as they require you to come up with a large sum at a specific time, and refinancing isn't always possible depending on market conditions.
