Traditional Versus Roth Crossover Calculator
Traditional Versus Roth Crossover: a planned Super Calculator tool. Covers contribution (USD). Stub page while the tool and its worked example are prepared.
Traditional Versus Roth Crossover Calculator is a planned calculator in the finance section of Super Calculator, covering retirement.
What this calculator will compute
Inputs: contribution (USD), current marginal rate (%), expected retirement marginal rate (%), expected return (%), years and whether the tax saving is invested.
Outputs: after tax value under each (USD), break even retirement tax rate (%) and recommended account.
Formula, recorded as scope and not yet verified against a primary source: Compares after tax terminal wealth: a traditional contribution grows on the full pre tax amount and is taxed at the withdrawal rate, while a Roth contribution grows on the after tax amount and is untaxed. The two are equal when the contribution and withdrawal marginal rates are equal, so the answer turns entirely on the rate differential and on whether the tax saving is actually invested.
