What this table tells you
Early payments are heavily weighted toward interest — most of your first-year payments build little equity
The crossover point marks when principal exceeds interest in each payment — a key equity milestone
Refinancing before the crossover point means paying interest twice on the same principal
Higher rates dramatically inflate total interest — compare the split bar as you adjust
How to use this strategically
Extra principal payments in early months eliminate interest from every row below them
Bi-weekly payments create one extra monthly equivalent per year — reducing term and total interest
Compare two loans by total interest — not monthly payment — to see the true cost difference
Use this table when evaluating prepayment — verify the penalty is less than the interest you'd eliminate
This table uses standard amortization math: each payment = fixed amount, with interest computed on the remaining balance each period. Bi-weekly is calculated as 26 payments per year. Actual lender schedules may vary slightly due to rounding conventions, origination dates, or irregular first periods. Consult your loan agreement for the authoritative schedule.
