Frequently Asked Questions

Everything you need to know.

What does an example Roth IRA vs High-Yield Savings Calculator calculation look like?
Using this calculator's own default assumptions, a monthly contribution of $500, years until withdrawal of 25 and high-yield savings apy of 4.4% produces an estimated roth ira final value of $475,513 and total contributed of $150,000. Enter your own numbers above to see how it changes for your situation.
Why does the Roth IRA usually win over time?
A Roth IRA grows completely tax-free, so every dollar of gains stays in your account and compounds further. A high-yield savings account taxes the interest you earn each year, which shrinks the amount available to earn future interest. Over a longer time horizon, this tax drag on the savings account compounds into a significant disadvantage, especially if your investments in the Roth deliver solid returns.
When would a high-yield savings account make more sense?
If your time horizon is very short, the Roth's advantage shrinks because there's less time for tax-free compounding to matter. Also, a high-yield savings account offers guaranteed returns with no market risk, whereas a Roth's value depends on your investment returns actually materializing. If you need money soon or can't tolerate market volatility, the certainty and safety of savings may outweigh the tax benefit.

Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.

Why This Matters

A Roth IRA grows tax-free and lets you withdraw gains without taxes in retirement, while a high-yield savings account charges tax on interest earned each year. Over time, this tax difference compounds: the Roth's tax-free growth accelerates your wealth, while the savings account's annual tax drag reduces what actually stays in your pocket. Knowing which account wins for your situation helps you direct contributions to the strategy that keeps more money.

How to Use It

  1. 1Enter your planned monthly contribution amount.
  2. 2Enter how many years until you plan to withdraw funds.
  3. 3Enter the current APY you expect from your high-yield savings account.
  4. 4Enter the average annual return you expect from Roth IRA investments (typically stock market returns).
  5. 5Enter your marginal tax rate as a percentage to estimate taxes owed on savings account interest.
  6. 6Review the results showing total contributions, final values for both accounts, taxes owed, and which account comes out ahead.
