March 2026 Money Market Account Rates: Top Offers Up to 4.01% APY

As of March 29, 2026, the national average money market account (MMA) rate is 0.56%, according to the FDIC. Top accounts are now offering rates between 3% and 4.01% APY, with TotalBank providing the highest rate of 4.01% APY for a minimum balance of $2,500. Comparatively, a $1,000 deposit at 0.56% APY would yield $5.62 in interest after one year, while the same amount in a 4% APY account would yield $40.81. The Federal Reserve cut its target rate three times in 2025, which has contributed to declining deposit rates, underlining the importance of seeking the highest available rates for savings.
