What it means
Float describes cash that exists on paper but is not yet usable, and processing float is the internal, self inflicted portion of it. It starts the moment a payment arrives at the business and ends when the deposit is made.
Mail float is the time a payment spends travelling from the customer, and clearing float is the time the bank takes to make deposited funds available. Processing float is the only one of the three that a company controls entirely on its own, which is why treasurers attack it first.
The cost is easy to see. Money sitting in a drawer is money not repaying an overdraft or earning interest, so multiplying average daily receipts by the days of delay gives the permanent cash balance that the delay consumes.
Electronic payments have shrunk the problem without removing it. Remittances that need manual matching to invoices, cash collected weekly from retail sites, and payments held while a credit query is resolved all recreate the same delay in a modern form.
Standard fixes include lockbox arrangements where a bank collects and banks payments directly, daily rather than weekly banking runs, and automated cash application software that matches receipts to invoices. Each option is judged by comparing its annual running cost against the interest saved on the cash it releases.
Processing float also matters on the paying side, where slower internal handling of supplier payments quietly extends the time cash stays in the business. That is a benefit rather than a cost, though relying on it is risky, since a late payment reputation eventually shows up as worse supplier terms.
In practice
Real-world examples.
Example
A chain of garden centres banks its takings twice a week to save on courier costs. With average daily cash of $40,000, the practice creates roughly $120,000 of processing float, which the finance director eliminates by switching to a daily collection service.
Example
A commercial insurer receives premium cheques that must be matched to policy numbers before deposit. Automating the matching cuts the delay from three days to one, releasing about $2,000,000 of cash across the group.
Example
A construction supplier finds that payments arriving with no remittance advice sit unallocated for a week. Adding a customer portal for remittance details reduces unallocated receipts by 80% and shortens average processing time by four days, which also removes a recurring argument between the credit control and sales teams.
Think of it
“Processing float is the time between receiving a payment and actually having access to the money.
Formula
Calculation
Processing float = average daily receipts x processing days
Annual saving from reducing float = cash released x cost of funds
A wholesale business receives an average of $250,000 a day in customer payments and takes two working days to open, record and bank them. Processing float is $250,000 x 2 = $500,000 permanently tied up.
The finance team introduces same day banking and automated matching, cutting the delay to half a day. New processing float is $250,000 x 0.5 = $125,000, so the cash released is $500,000 - $125,000 = $375,000.
The company pays 6% on its overdraft, so the annual saving is $375,000 x 6% = $22,500. If the new software costs $9,000 a year to run, the net benefit is $22,500 - $9,000 = $13,500 every year, plus a one off improvement in the cash position.Case study
Seen in the real world.
This is an illustrative and fictional example. Ferngate Utilities Services, an invented maintenance contractor, ran a permanent overdraft of around $500,000 and assumed it was simply the cost of slow paying customers.
A review found the real problem was internal. Cheques and card settlements arrived at a single office, were logged manually against job numbers by one part time clerk, and were banked only when the batch was complete, which took two days on average against daily receipts of $250,000.
Moving to daily banking and automated allocation cut the delay to half a day and released $375,000, which the fictional company used to clear most of its overdraft and save $22,500 a year in interest. The illustrative point is that the cheapest source of cash is often the money a business already holds but has not yet banked.
Watch out
Common mistakes.
- Assuming electronic payments removed float entirely, when manual allocation and weekly collection routines recreate the same delay.
- Measuring float only on the day of a month end review, which misses the fact that it is a permanent balance rather than a one off timing quirk.
- Focusing on chasing customers for faster payment while ignoring the internal days lost after the money has already arrived.
Questions
People also ask.
How is processing float different from mail float?
Mail float is time the payment spends reaching you, while processing float is time lost inside your own business before banking.
Does reducing processing float increase profit?
Indirectly yes, because the released cash reduces interest costs or earns a return, though revenue itself is unchanged.
What is a lockbox?
It is an arrangement where customers pay into an account the bank collects and processes directly, removing most internal handling time.
