What's the lifetime interest cost on $100K over 2 years?

You are projected to pay $6.91K in total interest. Keep in mind that during the first few years of the amortization schedule, your payments are heavily skewed toward interest rather than principal.

Is $100K a reasonable amount to borrow?

Borrowing $100K makes sense for appreciating assets or necessary purchases (like reliable transportation). Ensure your total debt obligations don't surpass 36% of your gross income.

Is a 2-year term better than a 7-year term for $100K?

2 years represents a solid middle ground. Pushing to 7 years dramatically increases the total interest ($6.91K), making the overall cost of borrowing disproportionately high.

What's the best strategy to pay off $100K faster?

Focus on making bi-weekly payments or applying entirely principal-only payments whenever you receive a tax refund or work bonus. A single extra $1,000 payment now saves exponentially more down the line.
