About JetFin

JetFin — where “Jet” symbolizes speed and “Fin” stands for Finance. It is a simple, fast, and intuitive tool designed for everyday buyers.

It empowers users to "know their numbers" and see exactly where their money is going, from principal to interest, before speaking to a salesperson or committing to a purchase.

While the name might suggest private jet financing, JetFin is actually built to help individuals quickly calculate and understand their auto or mortgage payments, without requiring any background in finance.

How It Works

Under the hood, JetFin runs detailed amortization calculations and presents the results through clear, insightful visuals.

The interactive donut chart breaks down the total cost of the loan, showing how much goes toward principal versus interest over the loan’s lifetime.

The stacked bar chart displays monthly payments split between principal and interest, helping users visualize how their payments evolve over time.

Finally, the full amortization table provides a month-by-month breakdown of every payment including the remaining balance, making the entire financing journey transparent and easy to follow, whether you're shopping for a car or a home.
