Zero-fee IRAs can still cost savers $1,400 a year

PensionBee has attached a real number to the word 'zero.' The online retirement provider's new white paper identifies six ways a fee-free IRA can still generate revenue for the firm that holds it, and almost none of those costs shows up on a statement. InvestmentNews first reported the findings, which land while the flow of money from 401(k) rollovers into IRAs is accelerating.

IRA assets are increasingly refilled by workplace plans. Every rollover is a moment when a saver parses marketing claims under time pressure. This paper is aimed at those moments, when the word 'free' sits at the top of a comparison table and the actual cost sits somewhere below.

To make the math concrete, the study applies its model to a $107,000 balance, roughly the median retirement savings for Millennial and Gen X households. In a cost-optimized account, the hidden annual drag runs from 0.16% to 0.32% of assets, or $160 to $340 a year. Assume typical saver behavior rather than disciplined fund selection, and the annual cost climbs to about 1.3%, or close to $1,400 on that same balance. The report is based on an independent analysis PensionBee commissioned.

Romi Savova, PensionBee's founder and chief executive, framed the research as a translation exercise. 'Industry experts know that investment services do not generally come for free,' she said. 'That may not be as clear to someone opening an IRA for the first time, which is why we commissioned this research to measure what zero actually costs.'

Six revenue streams form the paper's map, and the first three will look familiar to anyone who has studied brokerage economics. A cash sweep spread captures the difference between a low-yield holding account and a market rate, with the platform keeping most of the interest. Securities lending lets the provider loan out the saver's portfolio to institutional borrowers and collect a fee while the saver carries the risk. Payment for order flow routes trades through a middleman who pays the platform, instead of executing directly on a public exchange.

The most expensive channel is also the most ordinary: fund selection. An actively managed fund can charge close to nine times as much as a comparable index fund and still be marketed inside a zero-fee product. The paper estimates that a saver who picks the active fund and holds it for 30 years at a 7% return loses more than $170,000 from the ending balance. No fee line ever appears.

The report counts six channels, but the single decision that does the most damage is the fund pick. That makes this as much a behavioral finance study as a fee study. A saver can be careful about the broker and careless about the fund, and the fund decision swamps everything else.

None of these costs is a fee, which is exactly the problem. A cash sweep spread is a yield differential. Securities lending is a revenue share. Payment for order flow is a brokerage arrangement. Each has a legitimate business purpose. Each also changes the economics of an account that is marketed as free.

PensionBee does not claim every provider uses every channel. Its argument is that a statement offers no way to tell which ones are alive in any given account.

For advisers who handle rollover decisions, the paper is a reminder that the word 'zero' describes the list price, not the cost of ownership. The gap between a disciplined account and a typical account is roughly a percentage point a year. On $107,000, that is about $1,000 in annual hidden cost, compounded for decades.

For clients moving money out of an employer plan, the report turns a vague distrust of 'zero' into a short list of questions: what does the cash sweep pay, who keeps the lending fee, how are trades routed, and what do the funds charge. The list is specific enough to ask a provider directly.

PensionBee does not single out a provider, and it does not call the pricing deceptive. The paper's claim is more modest: a saver can read a full annual statement and still not know what the account costs. The useful question for anyone moving a 401(k) balance is about which of the six channels the provider uses, not the advertised fee. It is a question the statement cannot answer.
