While investors obsess over percentage allocations to stocks and bonds, many overlook where those assets are held—a decision that can meaningfully impact long-term after-tax returns. Use this Asset Location Calculator to determine the optimal placement of your investments across tax-advantaged and taxable accounts, helping you minimize tax drag and maximize after-tax returns.

How to use the Asset Location Calculator
The Asset Location Calculator is designed to help you pressure-test retirement savings, contribution strategy, tax tradeoffs, and long-term investing outcomes before you make a real-world change. Instead of relying on one rough estimate, run a few scenarios with conservative, base-case, and optimistic assumptions so you can see how sensitive the result is to returns, contribution levels, inflation, taxes, or timing.
A calculator result is most useful when you connect it to the account or plan decisions you actually control. After reviewing the output, compare it with your current savings rate, employer match rules, investment menu, expense levels, and withdrawal or rollover options. That is where MyPlanIQ's plan pages and retirement research become useful companions to the raw number.
If the result looks weak, treat that as a planning signal rather than a dead end. Small changes such as contributing earlier in the year, capturing the full company match, lowering fees, adjusting withdrawal assumptions, or choosing a more suitable allocation can materially change long-term outcomes. Re-run the calculator after each change and use the related links below to keep moving from estimate to action.

Calculator FAQs
What inputs should you change first in this calculator?
Start with the assumptions you can control in real life, such as contribution amount, retirement age, withdrawal rate, fees, and asset allocation. Then test optimistic and conservative versions so you can see which inputs change the outcome the most.
How should you use a calculator result?
Treat the result as a planning scenario rather than a prediction. Compare it with your workplace plan rules, savings rate, expected retirement timing, and investment options before making a real portfolio or contribution decision.
What should you do after reviewing the output?
Use the related links to compare retirement plans, read the connected MyPlanIQ article, and test one or two adjacent calculators so you can move from a single estimate to a fuller decision framework.
