How much money should I keep in my checking account?

Why not keep more in checking?

Most checking accounts pay 0.00–0.05% APY versus 4–5% at a high-yield savings account. On $10,000 of excess balance, that's $400–$500/year of forgone interest, plus loss of purchasing power to inflation. Money sitting in checking is the single most common avoidable cost in personal finance.

The recommended structure

1) Checking with 1–2 months of bills as buffer (e.g., $4,000–$8,000 if essentials are $4k/mo). 2) HYSA with full emergency fund (3–6 months). 3) Brokerage with long-term investments. Use an automated weekly transfer to pull anything above the checking buffer into HYSA every Friday.

Frequently Asked Questions

What about overdraft protection?

Link checking to your HYSA as overdraft backup instead of paying a $35 overdraft fee. Banks that charge overdraft fees on a $3 latte are why this category is the most consumer-hostile in banking.

Should I use the same bank for checking and savings?

Convenient but usually suboptimal. The big banks pay 0.01% on savings. Better: keep checking at a megabank for ATM access, savings at an online bank for the 4–5% yield. Transfers between them take 1–3 business days.

How much is too much in checking?

Anything beyond 2 months of expenses. If you find $20k+ sitting in checking, you're losing $800+/year. Move the excess to HYSA the same week.
