Three products worth opening

Varo - a savings rate attached to a checking account

Paid referral - this site earns $30.42 per approved signup

For the money you are saving but cannot lock away. That is the slot most people's savings actually sits in: it has to stay spendable this month, so a CD or a brokerage account is the wrong container, and the right container is a bank account that pays something.

The arithmetic

On $5,000 held all year. 3.75% APY applies to the first $5,000 and 1.00% to the rest, both read from varomoney.com on 27 October 2026; $5,000 × 0.0375 = $187.50, ÷ 12 = $15.63 a month. The 0.01% line is what several large national banks still post on a default savings account - substitute the rate printed on your own statement and the gap is yours, not mine. The bars are drawn to the same scale, which is why the last one is a hairline: it is widened to 1% so you can see that you can barely see it.

What it is, and what it costs

Varo's page lists no minimum balance fee, no overdraft fee and no in-network ATM fee, and it advertises cash advances of $250 right away building to $700 over time. That second one is the reason people in a biweekly-pay cycle open it rather than the interest: a repair in week one of a pay period has usually meant a payday loan, and an advance against money you have already earned is a different order of cost. Read the fee shown on the advance itself before taking one; this is not a loan product and it is not free money.

• What it pays this site: $30.42 when your account is approved - not when you click, when the bank says yes.
• What it asks of you: an application with your SSN and ID, and funding. Approval is Varo's decision, and a referral usually goes unpaid if it declines.
• What will put you off: there are no branches and no counter. The rate follows the federal benchmark, so it falls when the benchmark falls. The best tier caps at $5,000.

Skip it if

Not for you if you need branch service, or if you already hold a high-yield savings account at a real bank. Do not open a third account for a bonus and leave it idle; the only version of this that works is money that actually sits there.

Read the emergency-fund guide first - it decides how many months of spending must stay reachable before any of it moves.

Acorns - spare change that leaves the card

Paid referral - this site earns $28.80 per approved signup

For the specific failure mode where saving does not happen because the money is gone before the transfer date. Round-ups take the difference between what you spent and the next dollar and move it on its own, so the decision is made dozens of times a day at a size too small to argue with.

The arithmetic

A coffee at $2.80 sends 20 cents, so five of those a day is about $1 a day and $365 a year. The plan prices on acorns.com/pricing as of 27 October 2026 are $4, $8 and $12 a month, so the fee is $48 a year at the bottom tier; the $20 welcome bonus is five months of it. The arithmetic only holds for spending you were doing anyway, on a card you link.

What it is, and what it costs

The offer's own condition is a $5 recurring investment, which is also the smallest honest answer to "can I actually start this". Then it is a brokerage account, which is the part people skip: the money is invested in the market, it can lose value, and it is not FDIC-insured the way a bank balance is. If the number you are moving is money you will need in March, this is the wrong home for it and the account above is the right one.

• What it pays this site: $28.80 per qualifying signup.
• What it asks of you: link a card and set a $5 recurring investment; the bonus terms are Acorns' and can change, so check the screen you land on.
• What will put you off: a subscription fee on top of the market risk, and $8 or $12 a month if you let a sales screen talk you into a higher tier.

Skip it if

Not for you if $48 a year is money you need, or if you are already investing through an employer plan or a low-cost brokerage. Paying a subscription to automate what you already do by hand is the one way this goes wrong.

Do the ladder by hand for a month first - if the amounts are already moving, you do not need to pay for the same job twice.

Stash - the $5 entry, priced honestly

Paid referral - this site earns $21.01 per approved signup

For someone who has decided they want to own equities and is stopped by the entry size rather than the intent. Fractional shares mean the barrier used to be a minimum deposit; Stash's offer is a $5 invest, and the welcome bonus attached to it is $25.

The arithmetic

$25 ÷ 12 months = $2.08 a month. That is the whole test, and it is worth doing before you sign up rather than after: if the plan you are shown costs more than about two dollars a month, the bonus is consumed inside the first year and you are paying a subscription to hold five dollars.

Stash's pricing page returned a 404 to this check on 27 October 2026, so there is no current fee figure this site is willing to print. Read the price on the signup screen and compare it to the $2.08 above. If the number on the page disagrees with anything here, the page is right and this paragraph is the one that is stale.

What it is, and what it costs

Open the account and invest $5. That $5 leaves your bank balance and enters a market position, which is fine as a lesson and a bad idea as a habit if it is also your buffer.

• What it pays this site: $21.01 per qualifying signup.
• What it asks of you: an account and $5 invested, plus a monthly subscription whose current price you should read for yourself.
• What will put you off: the fee-to-balance ratio at small sizes. A subscription on a $5 position is a very high percentage, and the maths does not improve until the balance does.

Skip it if

Not for you if that $5 is your buffer. Get to a $100 cash cushion first, then decide whether the money you are adding should be invested or saved at all.

The first $100 guide is the predecessor to this one; if you are not past it, stop here and read that instead.
