Which retirement accounts should be funded first?

Detailed Explanation

Generally: any employer contribution you are leaving on the table, then tax-advantaged accounts, then ordinary taxable investing. An employer match is an immediate return on the contribution and is usually the highest-certainty step available. Tax-advantaged accounts come next because the shelter compounds alongside the returns. The specific vehicles and their limits depend entirely on where you live and how you are employed, so the ordering above is a shape rather than an instruction. The one general rule is to use the capacity you have before adding to accounts with no advantage.
