In the early years, almost all of each payment goes to interest. This is called "front-loading", and it is the financial equivalent of a shader compilation stutter: nothing seems to happen for a very long time, then suddenly it's 2049.
Each year in your schedule shows how much you paid, how much of that was interest, how much actually bought graphics card, and how much you still owe. The "Still owed" column is your equity in reverse. Watch it fall, slowly, like a fan curve at idle.
