Set your inputs and units
Enter amounts in THB and choose a period and rate basis that match the scenario you want to model.
Balloon loan
Calculate regular payments and the additional final balloon, including a monthly reserve for that obligation.
Result
Enter your assumptions and calculate payments and remaining debt.
Monthly model: interest and payments round to cents; the final payment clears the balance. Extra payments follow interest and regular payment. Total payments already include extras.
The balloon is added to the last regular payment. Balloon savings assume 0% interest and use the entered balloon before any effect of extra repayments.
This is an estimate, not a loan offer or an exact lender statement.
How to use this calculator
Check the assumptions
Review contribution timing, day-count basis or reserve duration. Financial products do not all use the same rules.

A worked example
Illustrative calculation
At 0%, a 120,000 THB loan over 12 months with a 24,000 THB balloon requires 8,000 THB regularly and 32,000 THB in the final month.
Compare a second scenario
Copy your first result, then change only the amount or duration to see how that assumption changes the outcome.
Common questions
Where does my information go?
Calculations run in your browser. Financial inputs are neither saved locally nor sent to analytics. Reloading restores the initial values.
Does this match a bank statement or guarantee a return?
This is an estimate under your assumptions, not a guaranteed return. Actual payment dates, fees, taxes and contractual rounding can change the result.
