Factoring Cost

Why this comes up

Factoring solves a real cash problem, advancing you most of an invoice's value before the client actually pays, but the fee is a real cost that belongs in your profitability math, not treated as an abstract financing-line expense. This engine computes the exact fee for a specific invoice, flat or incremental, so you know precisely what you're paying for the acceleration.

How we calculated this

Initial Fee = Invoice Amount x Initial Fee Rate
Incremental Fee (if used) = Invoice Amount x Incremental Fee Rate x Incremental Periods Beyond the Initial Period
Total Factoring Fee = Initial Fee + Incremental Fee + Other Flat Fees
Net Cash Received = Invoice Amount - Total Factoring Fee
Simple Annualized Equivalent = (Total Fee / Advance Amount) x (365 / Days Outstanding)

Worked example, flat fee mode: $100,000 invoice, 90% advance, 2% fee, 30 days outstanding.

Total Factoring Fee = 100,000 x 0.02 = $2,000
Net Cash Received = 100,000 - 2,000 = $98,000
Advance Amount = 100,000 x 0.90 = $90,000
Simple Annualized Equivalent = (2,000 / 90,000) x (365 / 30) = 27.0%

The annualized figure is a comparison tool, not literally an APR, unless your factoring agreement independently states one.

What this means

• The fee is charged against the full invoice amount, not just the advanced portion, so it's a real cost regardless of how much of the invoice value you actually receive upfront.
• Incremental fee structures, which many real factoring agreements use, charge more the longer an invoice stays outstanding; a slow-paying client's true factoring cost can be meaningfully higher than the flat-rate headline suggests.
• The simple annualized equivalent lets you compare factoring against an interest rate on a like-for-like basis, but it's a comparison figure, treat it as directional, not as the agreement's actual legal cost of credit.

Common mistakes

• Using flat-fee mode for an agreement that's actually structured with incremental tiers, understating true cost on invoices that run past the first pricing period.
• Comparing the factoring fee percentage directly against an annual interest rate without annualizing it first, since they're not measured on the same time basis.
• Tracking factoring cost only as a general expense line rather than attributing it back to the specific accounts and invoices actually driving it.

Frequently asked questions

When should I use the incremental fee mode?

Whenever your actual factoring agreement charges an increasing rate the longer an invoice is outstanding, rather than one flat percentage regardless of days out, which describes many real factoring agreements.

Is the annualized equivalent the same as my agreement's APR?

No, it's a comparison figure computed from the fee and days outstanding, not a legally defined APR. Treat it as directional for comparing against alternatives, not as your agreement's stated cost of credit.

How does the advance percentage affect the cost?

It doesn't change the fee itself, which is charged against the full invoice, but it does change the annualized equivalent, since that figure is measured against the advanced amount specifically, the cash you actually have in hand.

Limitations

Compares stated terms only; actual approval, minimum volume commitments, and contract length requirements vary by factoring company and aren't modeled here.
