Float: money that is neither here nor there

Some words in finance describe things you can hold. Float describes something you cannot quite pin down. Float is what you call money once it has left one place and before it has fully arrived in another. It is in transit, in suspense, between ledgers. And because it is between, it tends to belong to whoever is holding it at the time.

The word has meant slightly different things across the history of payments, but each meaning shares that sense of in-between. Understanding it explains why some businesses like to hold your money for a while, and why the timing of a payment can be worth something to someone.

The cash drawer

The simplest float is in a shop till. At the start of a shift, a cashier receives a fixed amount of change, perhaps a few notes and a roll of coins, so that the first customer can be given change. That starting amount is called the float. At the end of the day, the takings are counted after the float is taken out.

Nothing is in transit here, but the idea of money set aside to keep things moving is already present.

The check era

The financial meaning grew up with paper checks. When you wrote a check, the money stayed in your account until the check traveled through the clearing system to your bank. Meanwhile, the person you paid might already have deposited it and seen it credited, provisionally, to theirs. For a day or several, the same money appeared in two places at once.

That overlap was float. People and businesses learned to use it: paying bills by check just before payday, knowing the money would not leave for a few days. Banks learned to manage it, and rules on how quickly funds must be made available grew partly in response.

Float in electronic payments

Faster electronic payments have shrunk check float in many places, but float has not disappeared. It has moved.

• Card payments settle a day or more after authorization, as we described in the cast behind every card payment. In that gap, money is committed but not yet moved.
• Payment platforms may hold sellers' funds for a period before paying them out.
• Refunds can take days to arrive, while the money has already left the merchant.

Each of these gaps creates a balance that sits somewhere while it waits.

Float as a business model

When money sits with a business for a while, that business can usually hold it in an account that earns interest or otherwise benefits from it. With small sums and short delays, the benefit is tiny. Across millions of customers and longer delays, it can be significant.

That is the less visible meaning of float: the value of holding other people's money for a time. Gift cards, stored-value apps, card balances, subscriptions paid in advance and deposits all create it. Insurance companies are a well-known example: they collect premiums now and pay claims later, and the money in between is often called their float.

Float and card balances

A virtual card like ours is, from one angle, a float machine. You load money before you spend it, and until you spend it, it sits in an account managed on the card program's side. In regulated systems, rules often require that customer funds held this way be safeguarded, for instance kept separate from the company's own money, so that they remain the customers' if the company fails.

What matters to you is less the float than its treatment: is the balance yours, can you get it back, and under what conditions?

Where float hides in fine print

Float shows up in terms that never use the word:

• "Funds will be available within X business days" describes a period when money is somewhere else;
• "Unused balances expire after" describes float that is never returned;
• "Refunds are issued as store credit" keeps float inside the business;
• "Payouts are made weekly" gives the platform a week of float.

None of these is necessarily unfair. Each is worth noticing, because each decides how long your money spends between places.

Breakage: float that never comes back

A related word is breakage: the portion of value paid in advance that is never used. Gift cards that are lost, small balances that are forgotten, vouchers that expire. For the issuer, breakage is float that turns into income.

Some places limit how short expiry periods can be or require unused balances to be handled in specific ways. A business that relies heavily on breakage has an incentive to make balances easy to forget.

Why the word is useful to you

Thinking in terms of float helps you ask the right questions:

1. When I pay, when does the money actually leave me?
2. When I am paid or refunded, when does it actually arrive?
3. Who holds the money in between, and what are the rules for it?
4. What happens to a balance I do not use?

Those four questions apply to checks, cards, apps, deposits and gift cards alike.

How we handle the in-between

On our side, the money you pay sits in two states. Before a card is issued, it is a payment we are checking. Once the card exists, it is the card's balance. Our refund policy sets out what happens to a balance you do not use: untouched cards return their whole balance, and used cards above a threshold can return theirs less a handling charge. The rule is written down before you pay, not discovered afterwards. The help center explains how to ask for a refund.

A small vocabulary around float

• Clearing: the process of exchanging and reconciling payment instructions.
• Settlement: the actual movement of money between institutions.
• Availability: when funds can be used by the recipient.
• Hold: an amount reserved but not yet moved.
• Breakage: value paid in advance that is never redeemed.

Questions people ask

Is float the same as interest?

No. Float is money held in between; interest is one way of earning from it.

Do card companies earn from float?

Some programs earn interest on safeguarded balances, depending on the rules that apply. Many also rely on fees.

Can I avoid float?

Not entirely, but you can choose services that settle quickly, refund in money rather than credit and do not let balances expire.
