Costs & Taxes

What you earn is not always what you keep.

Investment performance is only the starting point. Advisor fees, fund expenses and taxes in a taxable account can each reduce the amount left working for you.

Retirement Reality Check

Project your retirement runway, translate the result into today's dollars, compare your spending target and see how annual investment costs can change the modeled outcome.

Two working calculators

Make the invisible costs visible.

Use each tool separately, or use the tax result as an input in the advisor-cost model.

Three different drains

Don't blend everything into one mysterious percentage.

ADVICE

Advisor fee

What you pay for financial planning, investment management and other adviser services. Value can include more than investment performance, so cost should be weighed against services received.

INVESTMENT

Fund expense ratio

The fund's own operating expenses. Published total returns generally already reflect these fund-level expenses, so they should not be subtracted a second time from historical total-return data.

Tax efficiency signals

What to look at before calling something “tax efficient.”

Account type

Taxable brokerage, traditional retirement and Roth retirement accounts have different tax treatment. Start here before judging an investment's tax efficiency.

Portfolio turnover

Higher turnover means more trading inside a fund and may create more taxable consequences when held in a taxable account.

Fund structure

Many ETFs can distribute fewer capital gains than mutual funds because of in-kind exchange mechanics, but ETFs are not tax-free.

Actual distributions

Look at the capital-gain distributions and dividends that actually appeared on your tax documents rather than relying only on a label such as “active,” “passive,” or “ETF.”

Start with the bill you can see.
