The national average savings account pays about 0.46% APY. Over most of the last 15 years, that rate has been well below inflation, meaning savers lost purchasing power year after year.

From 2021-2024, the gap was brutal: savings APY averaged ~0.3% while CPI averaged ~5.5%. A 10,000 dollar savings balance lost about 5 percentage points of purchasing power each year — roughly 500 dollars in real-world buying power annually.

High-yield savings accounts (HYSA) and money-market accounts typically pay 4-5x the national average. The FDIC National Rate Cap captures the average, not the best available. For savers serious about preserving purchasing power: shop for HYSAs above CPI and review annually.

Methodology & Assumptions

Values for National Average Savings Account Rate come from FDIC National Rates and Rate Caps[1]; values for Consumer Price Index (CPI) come from BLS via FRED (CPIAUCSL)[2]. Both series are fetched at build time and refreshed every 24 hours via ISR.

The weekly cadence for National Average Savings Account Rate and monthly cadence for Consumer Price Index (CPI) mean the live value you see reflects the most recent public release, not a real-time quote.

Historical charts show the last 10 years (~260 trading days for daily series). Sparklines are visually uniform; small moves may be compressed.

Correlation and spread analyses (where present in the narrative) use Pearson correlation over the overlapping window.

Last reviewed reflects the most recent data point across both series; on ISR revalidation the visible date updates when new data arrives.
