Asset Location Calculator

Estimate the annual and cumulative tax cost of holding interest-bearing assets in a taxable account instead of tax-deferred alternatives.

Quick answer: Estimate simple cumulative tax drag for interest-bearing assets in a taxable-account scenario; the model does not value future withdrawal taxes or account constraints. Enter Bond/Interest-Bearing Allocation, Yield on This Allocation, Your Ordinary Income Tax Rate, and Years Held to personalize the estimate. It returns Annual Tax If Held in a Taxable Account, Annual Interest Income, and Simple Cumulative Tax Estimate so you can compare the impact before choosing a next step. Use it to compare long-term value, tax impact, risk, time horizon, and contribution choices.

Frequently Asked Questions

Everything you need to know.

What does an example Asset Location Calculator calculation look like?
Using this calculator's own default assumptions, a bond/interest-bearing allocation of $100,000, yield on this allocation of 5% and your ordinary income tax rate of 32% produces an estimated annual tax if held in a taxable account of $1,600 and annual interest income of $5,000. Enter your own numbers above to see how it changes for your situation.
Why does this calculator ignore withdrawal taxes?
This tool focuses only on the annual tax drag from interest income earned in taxable accounts. It does not model what happens when you eventually sell or withdraw the assets, because that tax depends on your cost basis, capital gains, and future circumstances. Use this estimate as one part of a broader asset-location decision.
How does my tax rate affect the result?
A higher ordinary income tax rate multiplies the cost of holding interest-bearing assets in a taxable account, because interest is taxed as ordinary income each year. A lower rate reduces that drag proportionally. This is why investors in higher tax brackets often benefit more from moving bonds to tax-deferred or tax-free accounts.
Is the Asset Location 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 Asset Location 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 brokerage accounts, or run Money Map to compare this investing & retirement decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (brokerage) 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

Interest and bond income is taxed annually at ordinary income rates when held in taxable accounts, creating a drag on growth that compounds over time. By modeling this tax cost upfront, you can compare whether moving assets to tax-advantaged accounts or choosing lower-yielding but tax-efficient investments makes sense for your situation. The longer you hold interest-bearing assets in a taxable account, the larger the cumulative tax burden becomes.

How to Use It

  1. 1Enter the percentage or dollar amount of your portfolio allocated to bonds or other interest-bearing assets.
  2. 2Input the annual yield or interest rate you expect this allocation to generate.
  3. 3Enter your marginal ordinary income tax rate (the rate at which interest income will be taxed).
  4. 4Specify how many years you plan to hold these assets.
  5. 5Review the three outputs: your annual interest income, the yearly tax cost, and the total cumulative tax drag over your holding period.
