Significant amounts. Adding $100/month to a $200,000 30-year mortgage at 6% saves $62,000 in interest and pays off loan 6 years early. Extra payments early in loan term save the most.
Depends on loan rate vs investment returns. If mortgage is 6% and you can earn 8% investing, invest. If loan is 8% and investments return 6%, pay extra toward loan. Consider risk tolerance too.
