A retiree near 70 called into the Talking Real Money podcast with a question that sounds technical but actually decides whether he keeps thousands of dollars or hands them to his lender. He has $150,000 left on a mortgage that started as a 5-year ARM and has floated up to 6.58%. He just received about $25,000 from a new income stream and wondered whether to send it to Rocket Mortgage or stash it in a high-yield savings account paying around 3.75% and pay the loan off in a lump sum later.

A retiree near 70 with a $150,000 mortgage at 6.58% and $25,000 available should pay down principal instead of parking cash in a 3.75% savings account, because the guaranteed 2.78% spread between mortgage cost and best available risk-free yields (1-year Treasury at 3.80%) creates a contractual losing trade after taxes.
