When is a Roth IRA better than a Traditional IRA?

A Roth IRA is mathematically superior if you expect your marginal tax rate in retirement to be higher than (or equal to) your tax rate today. Furthermore, Roth IRAs feature no Required Minimum Distributions (RMDs) during the owner's lifetime, allowing your money to grow tax-free indefinitely and pass tax-free to beneficiaries.

What are the 2026 IRA contribution limits?

For 2026, the statutory IRS IRA contribution limit is $7,000 for individuals under age 50, with an additional $1,000 catch-up contribution ($8,000 total) for workers aged 50 and older.

What happens if I don't reinvest the tax savings from a Traditional IRA?

If you spend the annual tax deduction rather than investing it, the Roth IRA wins by a massive margin in virtually every scenario. The mathematical parity of a Traditional IRA relies on diligently investing the annual tax refund to compound alongside your IRA balance.

Annuity Future Value & Tax Arbitrage Equations

Roth FV = C × [((1+r)ⁿ - 1) / r] × (1+r) | Trad Spendable = [Trad FV × (1 - RetTax)] + ReinvestedSavings

Tax arbitrage between accumulation years (marginal tax rate t₁) and distribution years (effective tax rate t₂) determines the optimal retirement vehicle. Exact IEEE-754 decimal compounding models full lifetime wealth accumulation without floating-point drift.

The fundamental distinction lies in when you receive the tax advantage. A Traditional IRA provides an immediate tax deduction when you contribute, but 100% of your withdrawals in retirement (both principal and earnings) are taxed at ordinary income rates. A Roth IRA offers no upfront deduction, but all growth compounds completely tax-free and 100% of qualified withdrawals in retirement are permanently tax-free.
