Frequently Asked Questions

Everything you need to know.

What does an example HYSA vs CD Ladder vs T-Bill Ladder calculation look like?
Using this calculator’s own default assumptions, $50,000 with savings at 4.27%, a CD ladder at 5%, T-bills at 4.4%, a 0.75 point rate cut after year 1, a 24% federal rate and a 5% state rate ends at about $52,803 in savings, $53,613 in the CD ladder and $53,105 in the T-bill ladder. Enter your own numbers above to see how it changes for you.
Why does the CD ladder win when rates fall?
The CD ladder keeps its locked rate in year 2 while the savings rate and the T-bill yield drop. If rates stay flat, the gap shrinks, and if rates rise, savings or T-bills can come out ahead.
Why is the T-bill ladder taxed differently?
Treasury interest is taxed by the federal government but not by states. Savings and CD interest is taxed by both, so a T-bill can beat a slightly higher bank rate in a state with an income tax.
Is the HYSA vs CD Ladder vs T-Bill Ladder Calculator free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the HYSA vs CD Ladder vs T-Bill Ladder Calculator affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to compare current savings rates, or run Money Map to compare this banking & savings decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (savings) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

A savings account pays more when rates rise and less when they fall. A CD ladder locks today’s rate. A T-bill ladder follows the market, and its interest is free of state tax. Which one leaves you with the most depends on whether rates drop and on your tax rates. This calculator puts all three side by side in dollars after tax.

How to Use It

  1. 1Enter the amount you plan to keep in cash.
  2. 2Enter the savings APY, the average APY of your CD ladder rungs, and the current T-bill yield.
  3. 3Enter how many percentage points you think rates could fall after the first year.
  4. 4Enter your federal and state tax rates.
  5. 5Compare the three balances after two years, then check the result if rates do not fall.
