It depends on your interest rate versus your expected investment return, plus your risk tolerance and the value of being debt-free. Paying extra on a loan gives a guaranteed return equal to the interest rate; investing might return more but isn't guaranteed. Higher-rate loans usually favour paying down; low-rate loans can favour investing the difference. Many people do some of both. This calculator quantifies the payoff side so you can weigh it.
Yes, significantly. Every extra dollar goes straight to the principal and then stops accruing interest, so extra payments both shorten the term and reduce total interest — often by a surprising amount over the life of the loan. Even small, consistent extra payments add up. The calculator lets you test different payments so you can see the effect before committing.
