I Keep Less Than $100 in My Checking Account. Here's Why

Many or all of the products here are from our partners that compensate us. It’s how we make money. But our editorial integrity ensures that our product ratings are not influenced by compensation. APY = Annual Percentage Yield.

Right now, my checking account has less than $100 in it -- and that's just how I like it.

Thankfully, I'm not on the verge of bankruptcy. I just keep almost all of my cash in the savings portion of my SoFi Checking and Savings (Member FDIC) account, where I rack up $760 a year in interest on my $20,000 in savings, and I don't have to lift a finger to get it.

Here's how I do it -- and how you can supercharge your savings with an HYSA.

One easy move to earn hundreds more a year

You don't need to have $20,000 in savings to make switching to an HYSA worth it. The national average APY is just 0.40%, per the Federal Reserve, and top HYSAs are offering more than nine times that.

Here's how much more you can make on smaller balances:

Balance Top HYSAs (3.80%) National Average (0.40%)
$10,000 $380 $40
$5,000 $190 $20
$2,500 $95 $10

If you're ready to start the switch, I recommend my bank of choice, SoFi®. It comes with:

  • An annual percentage yield (APY) of up to 4.50% on savings with direct deposit
  • Up to $50 in no-fee overdraft coverage with direct deposit
  • Access to paychecks up to two days early with direct deposit
  • No account fees or minimum deposits

To earn up to 4.50% APY on your savings, read our full review of SoFi Checking and Savings (Member FDIC) and open an account today.

I keep almost everything in my HYSA

Practically all of my cash is in my SoFi® savings account. I've set up all my automatic transactions to come out of savings, too: Bills, credit card payments, and more.

That means I can stash basically all my money in my HYSA and earn that sweet, sweet APY. I only keep about $100 in my checking account for emergencies -- and if I ever need more, I can instantly transfer cash from my savings.

Here's how I think about it:

I don't use my HYSA for:

  • Long-term investing: Like retirement savings and money in my brokerage account
  • A small checking cushion: About $100 to cover small emergencies (with the option to instantly transfer more)

I do use my HYSA for -- everything else, including:

  • Emergency fund: Three to six months' worth of expenses
  • Short-term savings: Money for vacations, home improvements, and other big purchases
  • Other in-between cash: Basically any money I'm not planning on investing

Open your HYSA in less than half an hour

Getting started with an HYSA is quick and easy. I did it a few months ago in less than thirty minutes, all from the comfort of my couch. Here's what to do:

  1. Compare accounts. Look for an HYSA with a high APY, no account fees, and FDIC insurance up to $250,000.
  2. Open your account of choice. Just provide some basic info to get started.
  3. Move your money. Move your cash to your new high-powered account.
  4. Update automatic transfers. Set up direct deposit and other automatic transfers with your new account.
  5. Close your old account. If it no longer serves a purpose, feel free to dump your old savings account.

Once you make the switch, your savings should automatically start racking up interest. It's that easy.
