The best cash management APY right now runs as high as 4.00 percent for new customers, though most established platforms are clustering between 3.25 percent and 3.60 percent for standard account holders as of December 2025. That spread matters more than it looks, because fee structures and premium tier requirements can erase the headline rate advantage entirely.
What the Current Rate Table Actually Shows
Betterment leads the pack with a 3.25 percent variable APY available to every customer, no premium tier, no minimum balance. New customers get a temporary boost of up to 0.75 percent through January 15, 2027 with a qualifying deposit, pushing the effective rate toward 4.00 percent for that promotional window. FDIC coverage runs up to 8 million dollars for joint accounts through Betterment's program banks, which is a meaningfully higher ceiling than the standard 250,000 dollar single bank limit most savers default to.
Wealthfront sits close behind at 3.30 percent, climbing to 3.95 percent through a referral bonus, also with zero fees and zero balance thresholds. Moomoo and Public both post 3.30 to 3.35 percent with no premium account requirement either. Webull and Robinhood tell a different story: both gate their top rates behind paid subscriptions, 3.99 dollars a month for Webull Premium and 5 dollars a month for Robinhood Gold, and both drop to noticeably lower yields for non premium holders. Webull's standard tier pays 3.25 percent only above a 25,000 dollar account value threshold, and just 0.50 percent below it.
Why the Premium Gate Changes the Math
A 5 dollar monthly fee sounds trivial until it's set against a real cash balance. On 5,000 dollars sitting in a Robinhood Gold account earning 3.25 percent, the 60 dollars in annual fees consumes a meaningful slice of the roughly 162 dollars in interest earned. Scale that same fee against 50,000 dollars and it becomes background noise. The premium tier calculus for Webull and Robinhood therefore depends heavily on account size, which is a variable that free tier competitors like Betterment, Wealthfront, Moomoo, and Public don't force savers to model at all.
Robinhood Gold does bundle in extras beyond the cash yield, including Morningstar research access, larger instant deposit limits, and reduced margin rates, so the fee isn't purely a yield tax. Webull Premium likewise stacks in features beyond the interest rate. Whether those extras justify the monthly cost depends on whether a trader actually uses margin, research tools, or higher deposit limits, not just on the cash yield alone.
FDIC Coverage Limits Deserve as Much Attention as APY
Insurance ceilings vary meaningfully across these platforms and rarely get the same billing as the headline rate. Betterment and Wealthfront both extend coverage up to 8 million dollars for joint accounts through their networks of program banks. Public offers up to 5 million dollars in FDIC insurance through its partner banks. Betterment's own checking product, by contrast, carries the standard 250,000 dollar FDIC limit through nbkc bank, illustrating that coverage figures can differ even within a single provider's product suite. Anyone parking a large cash balance for an extended stretch should confirm the specific program bank structure and conditions attached to that coverage rather than assuming a flat number applies across every account type at a given firm.
Trading Features Versus Cash Yield: The Underlying Trade Off
None of these six platforms compete purely on cash yield, and the differences in their core trading products shape who each cash account actually suits. Webull offers commission free trading across stocks, ETFs, and options, plus extended hours access and fractional shares, but has no fixed income or mutual fund offerings and relies on payment for order flow, which can affect execution quality. Wealthfront is built around automated portfolio management with 17 asset classes and tax loss harvesting rather than active trading. Robinhood has broadened well beyond its original zero commission pitch with Robinhood Legend, launched in October 2024, and Robinhood Strategies, introduced in March of this year, aiming at more sophisticated, expert managed portfolios. Moomoo pairs commission free trading with professional grade charting and real time data aimed at more technically inclined traders. Public keeps its feature set intentionally narrow, with no mutual funds or futures, but offers rebates on options trades and no payment for order flow on stock and ETF trades.
The practical takeaway is that a saver optimizing purely for idle cash yield with no fee and no minimum balance should look first at Betterment, Wealthfront, Moomoo, or Public. A trader who already values margin access, advanced charting, or bundled research might reasonably accept the Webull or Robinhood premium fee if their account balance and feature usage justify it.
Which Rate Structure Holds Up Longest
Every APY cited here is variable and tied to broader interest rate conditions, so today's 3.25 to 4.00 percent range isn't a fixed promise. Promotional boosts, like Betterment's rate through January 2027 or Moomoo's extra 4.25 percent running through December 31, 2025, carry expiration dates that savers need to track closely. The open question for anyone parking cash on these platforms is how quickly these yields compress if broader rates fall, and whether the no fee, no minimum structure at Betterment, Wealthfront, Moomoo, and Public keeps its edge once promotional periods lapse.
