Creator Fee Analysis

Gross-base and net-base fees differ because the same rate is applied to a different starting amount. A Gross base uses the amount before the deductions named in the fee definition. A Net base uses the remaining amount after those named deductions. Do not assume which deductions count: copy the proposal's exact definition, map it to a real statement, and calculate both interpretations when the wording is unclear.

The SirenCY-specific rate used for teaching on this page is the verified 35% agency fee. The revenue amounts, deductions and fee-base interpretations below are explicit fictional assumptions, not a claim about a universal OnlyFans statement or the fee base in a particular SirenCY creator agreement. For broader pricing structures, read the agency cost and pricing guide.

Define Gross base and Net base from written lines

“Gross” and “net” are incomplete until the document says gross of what and net of what. One provider may mean fan payments before any named deduction. Another may label a dashboard subtotal gross even though a prior adjustment has already occurred. One proposal may define net after a platform deduction only; another may include refunds or other specified items. Preserve the source labels and build the calculation from them.

A fee base is not the same as creator take-home. The base is the amount multiplied by the fee rate. Take-home is a later reconciliation that may include the agency fee, platform deductions, taxes, operating costs, currency conversion, reversals or other items applicable to the creator. This article stops at fee-base clarity and a transparent worked comparison.

Ask for one formula written with named statement lines. “Agency fee equals the stated rate multiplied by [exact base definition]” is useful. “We take a share of earnings” is not. If the provider cannot point to the line used each period, the creator cannot independently check the invoice.

The agency fee comparison worksheet turns the fee-base result into a like-for-like offer comparison. Return here whenever two offers use a similar rate but define the starting amount differently.

Complete an Assumption register before doing the maths

The Assumption register prevents a clean-looking calculation from hiding an unsupported input. Record the period, currency, source labels, gross amount, every named deduction, candidate net amount, rate, fee base and additional charges. Tag each item Verified, Written offer, Fictional teaching input or Unresolved.

Keep timing differences separate. A statement can include adjustments connected to an earlier period, while an invoice may use a calendar month or payout window. Do not force the amounts to match by changing the fee base. Record the difference, ask the calculation owner and reconcile it in the correct period.

Keep negative and positive adjustments visible. A refund, reversal or correction should retain its sign and source. If the written definition does not explain its treatment, mark it unresolved and calculate scenarios rather than selecting the interpretation that produces the preferred answer.

The worksheet is equally useful before signing and during an invoice review. Before signing, it reveals ambiguous words. During review, it maps those words to actual lines and makes a disagreement specific.

Statement period

The exact start and end dates represented by the example or actual statement.

Currency

The currency used for revenue, deductions, fees and payment; do not mix converted and unconverted amounts.

Gross label

The provider's exact written name for the amount before the specified deductions in this calculation.

Gross amount source

Statement line, export or account record from which the gross amount was taken.

Named deductions

Each amount removed before the proposed net base, with source and reason stated separately.

Net label

The exact written definition of the amount remaining after only the named deductions.

Fee rate

The verified or quoted rate; the SirenCY-specific teaching input on this page is 35%.

Fee base

Gross, net or another precisely defined subtotal. Never infer the base from the rate alone.

Included services

The work covered by the fee during this period.

Additional charges

Fixed amounts, tools or reimbursable costs outside the percentage calculation.

Adjustments

Refunds, reversals, corrections, prior-period items or timing differences shown separately.

Calculation owner

The person who prepared the worksheet and can answer a reconciliation question.

Evidence reference

The statement, written fee definition and working sheet version used.

Unresolved item

Any line whose source, period, currency, sign or treatment is still unclear.

Work the same 35% rate on two explicit bases

Teaching assumptions: one fictional statement period; one currency; Gross amount of $12,000; named deductions of $2,000; resulting Net amount of $10,000; no additional charges; no timing adjustments; and a 35% rate. These numbers are selected only to demonstrate the base difference. They are not expected creator revenue, a typical deduction or a representation of current platform mechanics.

Scenario A: stated Gross base

Fee base: $12,000

Rate: 35%

Illustrative agency fee: $4,200

Scenario B: stated Net base

Fee base: $10,000

Rate: 35%

Illustrative agency fee: $3,500

The difference is $700 for this fictional period because one formula applies the same rate to $2,000 more. The calculation does not tell the reader which base is fair or which one SirenCY uses for a particular creator. That decision requires the current written offer, service scope and account-specific numbers.

Repeat the calculation with the creator's own statement labels. If deductions are disputed, build separate labelled scenarios. Do not collapse them into an average or choose a base silently.

Reconcile the fee to the source statement

1. Freeze the period

Use one statement period and one currency. Do not combine a month of revenue with a different invoice period.

2. Copy the gross line

Record the amount and source label exactly as shown. Avoid renaming it to fit the model.

3. List deductions

Enter every deduction separately and mark whether the written fee definition includes it before the fee base.

4. Calculate the candidate base

Subtract only the deductions explicitly included in the chosen definition.

5. Apply the stated rate

Multiply the documented base by the rate once, with no hidden second percentage.

6. Add non-percentage charges

Keep fixed or reimbursable amounts visible instead of burying them in the base.

7. Reconcile

Tie the calculated total to the invoice or proposed fee and leave any difference unresolved until explained.

Keep a reconciliation difference field. If the calculated fee is $3,500 and the proposed invoice says $3,650, do not change the base to make it work. Record the $150 difference and ask whether it represents a fixed charge, prior-period adjustment, currency item or error. Add the answer only when the provider supplies a traceable explanation.

Version the worksheet when an assumption changes. Preserve the first calculation, the question sent and the corrected version. That history is more useful than a final number with no explanation.

Ask fee-base questions in plain language

  • What exact statement or account line is multiplied by the fee rate?
  • Which deductions occur before that line, and which occur afterward?
  • How are refunds, reversals and prior-period adjustments treated?
  • Does the invoice period match the revenue statement period?
  • Which services are included in the percentage fee?
  • Which fixed, tool or reimbursable charges sit outside it?
  • Who prepares the calculation and how can the creator reconcile it?
  • What happens when a source line changes or is later corrected?

Use the agency vetting checklist to combine fee clarity with service, evidence, reporting and access checks. A mathematically clear fee can still be attached to a service that does not fit the creator.

Copy the gross-versus-net fee worksheet

Assumption register and calculation row

Worksheet version | Statement period | Currency | Gross label | Gross amount | Gross source | Deduction line | Deduction amount | Deduction source | Candidate net label | Candidate net amount | Fee rate | Fee base definition | Calculated fee | Additional charge | Proposed total | Difference | Question owner | Evidence link | Resolution

Create one deduction row per item and one calculation version per interpretation. Put formula text beside the result. A future reviewer should be able to reproduce the fee from the source records without contacting the person who built the first sheet.

Finish with a clear decision: Defined and reconciled, Defined but not reconciled, Base ambiguous, Source unavailable or Additional charge unresolved. Do not mark the fee understood while any input that changes the amount remains unclear.

Turn the calculation into a fee statement you can compare

A completed calculation should be readable as a sentence, not only as a formula. Write the statement period, source currency, exact fee base label, amount on that line, percentage, calculated fee, additional written charges and proposed total. Then cite the page, export or proposal section that supplies each input. If the base label came from your own interpretation, mark it Candidate rather than presenting it as agreed.

Keep platform deductions, refunds, taxes, payment processing, advertising spend, contractors and agency charges in separate rows. They may all affect creator cash flow, but combining them into one unexplained net figure hides which party defined the deduction and when it occurred. A gross-versus-net review is useful precisely because it stops different cost categories from being silently moved above or below the percentage line.

When comparing two proposals, use the same fictional or account-derived revenue scenario and the same statement period. Do not apply Offer A to a gross figure and Offer B to a net figure, then compare the totals as if only the rate changed. Run both offers through the agency fee comparison worksheet, preserving every open assumption beside its result.

If a provider answers an ambiguity, add the written answer and create a new calculation version. Do not overwrite the earlier interpretation. The difference between versions shows exactly what the clarification changed. If the answer introduces another charge or a different period, add a new row rather than forcing the new information into the old formula.

The final state should tell the creator whether the fee is reproducible, not whether the service is valuable. Value depends on scope, creator workload, delivery evidence and fit with the actual bottleneck. Keep that wider decision separate so a tidy calculation is not mistaken for proof that an offer is suitable.

Source and method notes

SirenCY's current OnlyFans agency guide identifies SirenCY's 35% agency fee and the need to distinguish gross and net bases. The first-party OnlyFans calculator provides a separate handoff for modelling creator inputs; it does not define a proposal's commission base. This page rejects third-party industry ranges and other illustrative rates. Only the verified SirenCY rate is used; all statement values and deductions are explicitly fictional teaching inputs.

Limitations: the examples do not state a universal platform deduction, current SirenCY fee base, creator take-home or expected result. Actual calculation depends on the current written offer and creator statement. Replace every assumption with traceable account data before making a decision.
