Low-Cost Index Alternatives to TIAA CREF

The "CREF" in TIAA-CREF stands for College Retirement Equities Fund. These are variable annuities that behave similarly to mutual funds but come with an extra layer of insurance-related fees. For decades, these were the only options for many professors. But in 2026, the "Index Revolution" has made these high-fee active accounts look increasingly obsolete.

The active management myth

TIAA's active managers attempt to pick stocks that will outperform the market. However, after you subtract the fees they charge for this "expertise," the net return for the investor is frequently lower than a simple S&P 500 or Total Stock Market index fund. For example, a typical CREF Stock account might charge 0.45%, while a Vanguard Total Stock Market index fund charges 0.04%. That 0.41% difference belongs in your pocket, not TIAA's.

By building a "Three-Fund Portfolio" using low-cost indexes, teachers can achieve broad diversification across the entire global economy with maximum tax efficiency and minimum drag from fees.

Our research indicates that educators who switch to an index-based strategy often see their "projected retirement date" move earlier by 2 to 4 years simply because they stopped paying for underperforming active management. If your employer allows for "brokerage windows" (like TIAA's Personal Choice Account), you can often buy these low-cost indexes without even leaving the TIAA platform—though you'll still have to deal with TIAA's administrative fees.
