Common questions
Why include the remaining loan balance?
Payments can be lower because principal is repaid more slowly. Adding the unpaid balance compares the same horizon without treating delayed repayment as a free saving.
Are my model inputs saved or sent to a server?
No. This model runs in the current browser tab and creates a local JSON download. It does not save your input or call an external data service.
