- An interval fund is a closed-end fund that buys back only a limited slice of its shares at set intervals, usually 5% to 25% quarterly at net asset value. That structure is what lets it hold illiquid private assets.
- The interval is the catch. If more investors want out than the quarterly offer covers, redemptions are prorated and capped. In early 2026 the $33 billion Cliffwater Corporate Lending Fund did exactly that.
- Costs are high. Expense ratios often run above 1% to 2%, sometimes with performance fees, plus a repurchase fee of up to 2% on the way out, which quietly erodes the higher yield that drew you in.
An interval fund is one of the few ways an ordinary investor can buy into private credit and private real estate, the kinds of assets that used to require an institution or a seven-figure net worth. That access is real, and it is why the category has grown past $146 billion. But the most important thing about an interval fund is not the assets it holds. It is the word "interval," which describes exactly how hard it is to get your money back out.
Understand that one feature and you understand the product. Miss it and you can end up locked into an illiquid fund at the exact moment you want to leave.
How an interval fund actually works
A regular mutual fund lets you redeem any business day. An ETF trades on an exchange all day long. An interval fund does neither. It is a closed-end fund that does not trade on an exchange, and the only way out is through the fund's own scheduled buyback offers.
By rule, the fund makes a repurchase offer at set intervals, most commonly every quarter, to buy back between 5% and 25% of its outstanding shares at net asset value. You tell the fund you want to sell, and if the total requests fit inside that quarter's offer, you are cashed out. This is the FINRA description of the structure, and it is deliberately restrictive. The limited liquidity is the price of holding assets that are themselves illiquid.
The interval is the catch
Here is the part that turns a footnote into the headline. The repurchase offer is a ceiling, not a promise to buy everything. If more investors want out than the offer covers, the fund prorates redemptions. You might ask to sell your whole position and receive only a fraction, then wait for the next quarterly window to try again, subject to the same cap.
That is not a hypothetical. In early 2026, the Cliffwater Corporate Lending Fund, a roughly $33 billion private credit interval fund and one of the largest aimed at retail investors, capped its repurchases after redemption requests ran well past its quarterly limit (Bloomberg). Investors who assumed the quarterly window meant reliable access found the gate partly closed. This is the same liquidity mechanic that hit real estate crowdfunding platforms like Fundrise, and it is worth reading our real estate crowdfunding guide alongside this one, because the lesson is identical: private assets do not become liquid just because a retail wrapper is put around them.
The fees are higher than they look
The second thing the marketing understates is cost. Interval funds routinely carry expense ratios above 1% to 2% a year, sometimes with performance fees layered on, because managing private credit or real estate is expensive and the managers charge for it. On top of the annual cost, many funds charge a repurchase fee of up to 2% when you sell.
Put that against the pitch. If a fund advertises an 8% yield and charges 2% a year in expenses, a quarter of your gross return is gone before you see it, and that is before the exit fee. High fees are not automatically disqualifying if the underlying return justifies them, but they compound against you every year, so they belong in your decision, not in the fine print. Our private credit guide covers what those underlying returns actually depend on.
What interval funds are good for, honestly
None of this makes interval funds bad. It makes them specific. They suit an investor who wants genuine exposure to private credit or private real estate, has a long horizon, and can leave the money alone through a full market cycle without needing it back on demand. For that investor, the illiquidity is a tradeoff they are being paid to accept.
They are wrong for anyone who might need the money quickly. Emergency savings belong in high-yield savings. Money you want diversified but liquid belongs in index funds or a REIT ETF you can sell any trading day. The interval fund is a specialist tool, and its whole design assumes you will not be in a hurry.
Quick answers
Can I sell an interval fund whenever I want? No. Only during scheduled repurchase offers, usually quarterly, and only up to the offered percentage. Excess requests are prorated.
Are interval funds risky? They carry the risk of the private assets they hold plus liquidity risk, meaning you may not be able to exit when you want. That combination is the main thing to understand.
How are they different from a REIT ETF? A REIT ETF trades on an exchange with daily liquidity and low fees. An interval fund holds less liquid private assets, limits redemptions to set intervals, and charges more. Different tools for different jobs.
