Paying extra on a mortgage. How much can I save? [duplicate]
When is the best time to pay? At the end of each year? If you save $1,000 each month at 1% so as to pay $12,000 at EOY on a 4.75% loan, you've lost "4.75% - 1% = 3.75%" over that year.  (And that's presuming you put the money in a "high yield" online savings account.) Thus, the best time to pay is as soon as you have the money. EDIT: This all assumes that you have an emergency fund (more than the bare minimum $1K), zero other debt with a higher rate than 4.75% and that you are getting the full company match from 401(k).
