Should you payoff low interest debt or use that money to invest?

If you have a $250k mortgage at 3% and you pay an extra $100 per month you’ll save $19k in interest over 30 years.

If you instead invest $100 a month with a 7% rate of return, in 30 years you’ll have $118k.

A difference of $100k

Paying off low interest debt may not be your best move.
