“Paying off my mortgage gives me peace of mind.”
Suppose you have $100,000 and a 5% mortgage. Put the money toward principal and, after 10 years, you've captured about $163,000 of value. At the assumptions used in this piece, the same $100,000 grows to roughly $259,000 in the S&P 500 at 10%, or $619,000 in bitcoin at 20%.
Those returns aren't guaranteed, while the 5% savings is. Still, the comparison shows how expensive emotional comfort can become when the alternative has a decade to compound.
A 30-year fixed mortgage also gets easier to carry over time. The payment stays predictable while inflation reduces its real cost, and the lender can't demand more collateral because your house falls in value. That makes it very different from margin debt.
The other cost of prepaying is liquidity. Once cash becomes home equity, paying for a job loss or medical bill may require a refinance or sale. A liquid portfolio can be sold incrementally, cover years of mortgage payments, and keep compounding during normal times.
Of course, this only works if you can tolerate volatility, maintain a cash buffer, and invest the difference instead of spending it. The useful question is whether a zero mortgage balance makes you safer than having enough liquid assets to cover the payment for years.
