Tiered MMA Rates: What $75K Earners Need to Know
At $75K income your emergency fund balance (roughly $22,000) likely exceeds many banks' first tier thresholds and earns better rates. Always check whether your balance falls in the top rate tier. On a tiered MMA paying 3.00% under $10,000 and 4.75% above $10,000 a $22,000 balance earns the top rate on most or all of the balance.
Most tiered MMAs pay the tier rate on the portion of your balance in each tier (not your entire balance at the top rate). Example: 3.00% on first $10,000 and 4.75% on amounts above $10,000. On $22,000 you earn $300 on the first $10K and $570 on the next $12K = $870 total (not $22,000 x 4.75%).
Tiered MMA vs. flat-rate MMA on $22,000 balance
| Balance Tier | Rate | Annual on $22K |
|---|---|---|
| First $10,000 at 3.00% | 3.00% | $300 |
| Next $12,000 at 4.75% | 4.75% | $570 |
| Blended effective rate | 3.95% | $870 |
| Flat-rate MMA at 4.65% | 4.65% | $1,023 |
At $75K When to Use MMA vs. HYSA vs. CD
Emergency fund (needs instant transactional access): MMA or HYSA. Short-term goal savings (vacation, car, appliance, 1-12 months): HYSA or no-penalty CD. Down payment (fixed date in 12-24 months): CD for rate certainty. Long-term investing: retirement accounts and taxable brokerage.
- MMA: emergency fund — especially if you want check-writing for direct expense payments
- HYSA: additional goal savings where transactional features are not needed
- No-penalty CD: savings you are confident you will not need for 30+ days
- Standard CD: savings with a defined future date and commitment to the timeline
