The rule of thumb: if you expect a higher tax rate later, Roth usually wins; if you expect a lower one, Traditional usually wins. With equal rates they come out the same. Shown for one year's contribution of $7,500 of pre-tax income.

Simplified: assumes the same pre-tax budget for both and flat tax rates. Roth IRA eligibility phases out at higher incomes, required minimum distributions apply to Traditional accounts, and many people split contributions between both to hedge. Not tax advice.
