How can the Student Loan Tracker assist in determining the number of extra payments needed to pay down debt quickly?

The bar charts in the Student Loan Tracker aid in visualizing the total interest paid and saved across each loan by providing a graphical representation of the data. This allows users to easily compare the amounts of interest paid and saved across different loans. As the user changes the time ranges and amounts of extra payments, the bar charts update in real-time, showing the impact of these changes on the total interest paid and saved. This can help users understand the effects of their payment strategies and make informed decisions about how to manage their student debt.

The Student Loan Tracker calculates the total interest saved across each loan by considering the time ranges and amounts of extra payments. As these parameters are changed, the interest saved table updates to reflect how much interest is saved across each loan. This is done in real-time as you edit your extra payments, allowing you to see how each change impacts the total interest saved.
