What two advances at once actually cost in weekly outflow

The combined debit is the whole story

Two advances do not average. They add, every banking day, until one of them clears.

Illustrative only — an existing advance of $42,000 at a 1.35 factor repays $56,700 over 126 banking days, a debit of $450 a day. Two months in, with 84 debits left, a second funder offers $25,000 at 1.47, repaying $36,750 over 105 banking days, or $350 a day.

Combined, that is $800 a day, $4,000 a week and $16,800 a month at 21 banking days. Against $85,000 of monthly deposits, 19.8% of every dollar that arrives is committed before it can be spent.

The first advance alone was $2,250 a week. The second one did not add half again. It added 77.8% more, and it added it to a business that was already committed.

The marginal cost of the second deal

Price the new money on its own terms, not as an average of the two.

The second advance costs $11,750 on $25,000 over 105 banking days. Treating the debits as a level annuity, solving for the daily rate and multiplying by 252 banking days a year gives an annualised 197.1%.

Now apply the fees. With a 4% origination deducted, $24,000 reaches the account. The effective factor on the cash received is 36,750 / 24,000 = 1.5312, and the annualised cost on the same basis is 219.9%.

That is the price of the marginal $24,000, and it is the number the decision turns on — not the blended cost of both facilities, which is a figure that describes your past.

The two-month overlap

For the 84 banking days where both are running, the business pays $800 a day. Then the first clears and the debit drops to $350.

Businesses sign the second advance imagining the second number. They then have to survive four months of the first one. Write the overlap out week by week before signing: the count of banking days where both debits run, the combined weekly figure, and the free cash available in each of those weeks. If the overlap is where the business breaks, the fact that it gets easier in month five is irrelevant.

What the contracts say about it

Most advance agreements contain an anti-stacking clause: taking additional financing secured by the same receivables is an event of default under the first agreement. Whether the first funder enforces it is a business decision they make later, but the clause means the second advance can put the first one into default on the day it funds.

Read both agreements for the definition of additional financing. Some are drafted narrowly enough that a bank line or equipment finance is fine. Some cover any obligation of any kind. Some require written consent that is discretionary and rarely given.

If a broker tells you the first funder will not mind, ask for that in writing from the first funder.

When the arithmetic stops working

The honest test is whether the second advance produces cash faster than it consumes it. There are cases where it does — a purchase order with a signed margin, inventory that turns in six weeks, a payroll gap on work already invoiced.

The test is not "can I make this week's payments". It is: over the 84 days of overlap, does the business generate $800 a day of free cash plus what it needs to operate? If free cash was $450 a day before the second advance, the answer is arithmetically no, and the gap will be filled by payables, taxes, or a third advance at a higher price than the second.

Illustrative only — the third one

The reason to do this arithmetic before the second advance is that the third is the one that ends the business, and it looks exactly like the second did.

Combined, the daily debit is $1,066.07. At 21 banking days that is $22,387 a month, and against $85,000 of monthly deposits it is 26.3% of every dollar that arrives, removed before it can pay a supplier or a wage.

Price the new money on its own. With seven points deducted, $13,950 reaches the account against a $22,350 obligation — an effective factor of 1.6022 on cash received, which over 84 banking days annualises to 306.6%.

The pattern is the tell. Each advance is smaller than the last, each is more expensive than the last, and each is taken to service the previous one. By the third the marginal price has passed the point where any ordinary business activity can outrun it, and the decision is no longer a financing decision.

What the first funder sees, and when

Owners tend to assume the second position is invisible until something goes wrong. It is visible in three places, on a schedule you do not control.

• The UCC filing, which appears in a public index within days and is found by any search.
• Your bank statements, at the next renewal conversation or the next request for statements. A new daily debit on the page is not subtle.
• The deposit pattern, if the new funder requires a change of account or a lockbox.

So the practical question is not whether the first funder will find out. It is whether they hear it from you first, and whether you asked for consent before or explained yourself after.

The alternatives worth pricing first

• Asking the existing funder for a renewal or a top-up. Frequently more expensive than it sounds, because the unpaid balance is usually rolled in at a fresh factor. Price it as a refinance, not as new money — see refinancing arithmetic.
• Extending payables deliberately, with the supplier's agreement. Free if negotiated, ruinous if simply taken.
• Factoring specific invoices rather than borrowing against future revenue in general, if the receivable exists and the debtor is creditworthy.
• Doing less. Declining the order that requires the money is a legitimate answer, and a cheaper one than a 219.9% annualised marginal cost.

Run the combined debit, the overlap weeks and the marginal price through the calculators before you sign, and get the first funder's written consent or the answer to why it is not needed. The arithmetic on a second advance is not difficult. It is just rarely done before the money arrives.
