Frequently Asked Questions about Rates & Yields

Why do money market account rates change so frequently?
MMA rates are variable and typically move in line with Federal Reserve policy decisions. When the Fed raises or cuts its benchmark rate, MMA rates at most banks follow within 2-6 weeks. Competition among banks also drives rate changes.
How can I find the best money market account rate?
Compare APYs (not just interest rates) across at least 3-5 institutions. Online banks consistently offer the highest rates. Check the minimum balance required to earn the advertised rate, and verify whether the rate is permanent or a promotional intro rate.
What is APY and why does it matter?
APY (Annual Percentage Yield) is the actual annual return on your deposit after accounting for compounding interest. It is always slightly higher than the stated interest rate. APY is the correct metric for comparing accounts because it reflects what you'll actually earn.
