High-net-worth households in Michigan with credit card debt face a straightforward decision: 22% APR is nearly always more expensive than any after-tax investment return available. The S&P 500 has returned an average of 7.0% annually over long periods. Paying off a 22% card first is the dominant move.
The only cases where investing before full payoff makes sense: a 401k with a full employer match (50-100% immediate return), or a balance transfer at 0% promotional APR where you can pay off the full balance before the rate resets. Outside those scenarios, maximize payoff first, then redirect cash flow to taxable investment accounts.
