10, 15, or 30-year fixed rate mortgage amortization table showing % left

I made this because I could not find an amortization table on the web that shows total % of original balance left (as opposed to just the actual balance) after each payment. Here, you can see how the percentage deducted every month grows over time, and how it takes about 19 years through a 30-year mortgage to get it halfway paid off.
