Is a Roth or pre-tax retirement contribution better for my tax bracket?

The core question is whether your tax rate is higher now or will be in retirement. Pre-tax (traditional) contributions deduct from income today and are taxed on withdrawal, so they win if you're in a high bracket now and expect a lower one later, common for peak-earning professionals. Roth contributions use after-tax dollars now but grow and come out tax-free, so they win if you're in a low bracket today (early career, a low-income year) or expect higher rates or large balances later. Many people hedge by splitting between both, which also gives flexibility to manage taxable income in retirement. Roth also avoids required minimum distributions and helps heirs. A rough rule: 22% bracket or below leans Roth; 32% and up leans pre-tax. Compare the math at wealthserene.com/tools/roth-vs-traditional.
