Comparing 7-day yield and APY - updated

Two years ago I wrote a blog post on comparing 7-day yield and APY, but interest rates have changed a lot since then, so here is an update on some common interest rates we are seeing for CDs, money market accounts, and money market funds.

1.00% 7-day yield = 1.00% APY
1.04% 7-day yield = 1.05% APY
1.09% 7-day yield = 1.10% APY
1.14% 7-day yield = 1.15% APY

2.91% 7-day yield = 2.95% APY
2.96% 7-day yield = 3.00% APY
3.00% 7-day yield = 3.04% APY
3.45% 7-day yield = 3.50% APY
3.50% 7-day yield = 3.56% APY
3.93% 7-day yield = 4.00% APY
4.00% 7-day yield = 4.07% APY
4.44% 7-day yield = 4.53% APY
4.45% 7-day yield = 4.54% APY
4.50% 7-day yield = 4.59% APY
4.75% 7-day yield = 4.85% APY
4.89% 7-day yield = 5.00% APY
4.90% 7-day yield = 5.01% APY
4.94% 7-day yield = 5.05% APY
4.95% 7-day yield = 5.06% APY
4.96% 7-day yield = 5.07% APY
4.97% 7-day yield = 5.08% APY
4.98% 7-day yield = 5.10% APY
4.99% 7-day yield = 5.11% APY
5.00% 7-day yield = 5.12% APY
5.02% 7-day yield = 5.14% APY
5.03% 7-day yield = 5.15% APY
5.04% 7-day yield = 5.16% APY
5.05% 7-day yield = 5.17% APY
5.06% 7-day yield = 5.18% APY
5.07% 7-day yield = 5.19% APY
5.09% 7-day yield = 5.21% APY
5.10% 7-day yield = 5.22% APY
5.15% 7-day yield = 5.27% APY
5.18% 7-day yield = 5.30% APY
5.20% 7-day yield = 5.33% APY
5.22% 7-day yield = 5.35% APY
5.25% 7-day yield = 5.38% APY
5.27% 7-day yield = 5.40% APY
5.32% 7-day yield = 5.45% APY
5.37% 7-day yield = 5.50% APY
5.41% 7-day yield = 5.55% APY
5.46% 7-day yield = 5.60% APY
5.51% 7-day yield = 5.65% APY
5.56% 7-day yield = 5.70% APY
5.60% 7-day yield = 5.75% APY
5.65% 7-day yield = 5.80% APY
5.70% 7-day yield = 5.85% APY
5.75% 7-day yield = 5.90% APY
5.79% 7-day yield = 5.95% APY
5.84% 7-day yield = 6.00% APY
5.89% 7-day yield = 6.05% APY
5.94% 7-day yield = 6.10% APY
5.98% 7-day yield = 6.15% APY
6.03% 7-day yield = 6.20% APY

So, for example, my new money market account at Sovereign Bank is paying 2.75% APY which is equivalent to a 7-day yield of 2.72%. My Fidelity Select Money Market fund is paying a 7-day yield of 2.67% which is equivalent to an APY of 2.70%.
