2. Index funds simplify portfolio construction
Attempting to outperform the stock market is difficult even for professionals. Morningstar data show that just 8 percent of large-company U.S. stock mutual funds both survived and exceeded the S&P 500 over the decade ending June 2025. Rather than chase that slim probability, Benz recommends building a core portfolio with low-cost index funds that track broad market benchmarks.
Index funds offer multiple advantages: lower fees, automatic diversification, and a hands-off structure that reduces the need to monitor individual holdings. A single total-market equity index fund coupled with an aggregate bond fund can provide exposure to thousands of securities, spanning sectors, company sizes, and geographies. This coverage often matches or exceeds the diversification many actively managed portfolios strive to achieve, but with far less oversight.
3. Fewer financial relationships reduce friction
Interest-bearing accounts generate varying yields, but Benz cautions against constantly shifting cash to capture fractional increases. She suggests selecting a low-cost institution that reliably offers competitive rates and consolidating as many services there as practical. For brokerage customers, examining the yield on “sweep” accounts—where uninvested cash temporarily resides—can be more impactful than opening multiple savings accounts.
High-yield savings rates fluctuate, and moving funds repeatedly may provide little long-term benefit relative to the administrative burden. By housing checking, savings, brokerage, and even credit cards under one roof, investors often simplify record-keeping, streamline transfers, and make it easier for family members or future caretakers to locate assets. Consolidation should not preclude regular reviews; it merely limits the number of institutions that require attention.

4. Professional advice can fill in the gaps
Although Benz spends her career analyzing personal finance, she and her husband employ a financial planner for their own retirement plan. Outsourcing technical adjustments to an expert, she notes, frees time and provides reassurance that the plan remains optimized as tax laws, market conditions, and personal circumstances evolve.
Fee-only planners—who charge by the hour, per project, or via a subscription—are compensated directly by clients rather than through product commissions. That model helps reduce conflicts of interest, according to guidance from the U.S. Securities and Exchange Commission. While advisory fees add a cost, Benz contends the value can be worthwhile when weighed against the time saved and potential mistakes avoided.
Balancing efficiency and effectiveness
The four practices—automatic saving, index investing, account consolidation, and selective use of professional help—aim to deliver most of the benefits of full optimization without the corresponding workload. Each tactic targets a core component of financial health: consistent contributions, market exposure, administrative simplicity, and expert oversight where needed.
For households that prefer not to spend hours studying credit-card fine print, scouting short-lived deposit promotions, or timing the stock market, these guidelines offer a pragmatic middle path. By focusing on decisions with the greatest long-term impact and minimizing peripheral chores, investors can devote more attention to careers, families, and other priorities while still working steadily toward their financial goals.
