Arm's length range builder
Turn a set of comparable margins into quartiles, a range and a verdict.
Open itA royalty rate has to survive two tests: it has to sit inside the range of comparable agreements, and it has to leave the licensee a return. This runs both, on the rates you found and the margins your licensee actually earns.
The licence
Percentages of net sales from comparable licence agreements, adjusted to the same base as your tested rate.
%
The rate in the intercompany licence.
$
The base the royalty is charged on. Say clearly whether it is gross or net of returns and discounts.
%
Operating profit as a percentage of net sales, with the royalty added back.

Two tests, and the second one is the harder
Comparable agreements give you a range, and the quartiles of that range are the first test. They are also the easier one, because licence databases are noisy: the base differs from agreement to agreement, exclusivity and territory differ, and a rate on gross sales is not comparable to a rate on net sales without adjustment.
The second test is whether the licensee is left with a return. A royalty that consumes most of the licensee's operating profit is hard to defend whatever the database says, because an independent licensee with its own functions, assets and risks would not agree to it. The share-of-profit line is there to make that visible in one number.
Where the range is weakest
Published licence data rarely tells you what the licensee actually got in return, what else came bundled with the licence, or whether the parties were genuinely at arm's length on the day. So the range is a corroboration rather than a conclusion, and it is worth stating in the file what adjustments were made to bring the observed rates onto a common base.
Where the intangible is the main driver of the business, a profit-based approach that looks at the split of the residual is often more persuasive than a rate from a database. The share-of-profit figure here is a first look at that question, not a substitute for it.
Worked example
Eight observed rates from 2.0% to 6.0% of net sales. The intercompany licence charges 5.0% on 30 million of licensee sales, and the licensee earns a 12% operating margin before the royalty.
- The quartiles put the middle half of the observed set between roughly 2.9% and 4.6%, so 5.0% sits above the upper quartile.
- The royalty costs 1.5 million. The licensee’s pre-royalty operating profit is 3.6 million, so the royalty takes just over 41% of it.
- At the median rate the royalty would cost about 1.05 million, leaving the licensee materially more.
Drop the licensee margin to 5% and the royalty takes more than the whole operating profit. The range has not moved, and the position has become indefensible anyway.
What this calculator assumes
- Observed rates are assumed already adjusted to the same base, territory and exclusivity as the tested rate. That adjustment is the analytical work; this is the arithmetic on top of it.
- The licensee margin is entered before the royalty, so the tool can show the position on both sides of it.
- The share of operating profit is a diagnostic, not a rule. No jurisdiction sets a fixed share, and treating one as a rule is not defensible.
- A profit split or a residual analysis may be the better method where the intangible drives the business. Nothing here chooses the method.
An estimate, not advice. This is an estimate built from what you typed, not advice on your file. Nothing here reads your documents, checks your treaty article or looks at the year you are actually in. Where the number matters, we agree a fixed fee in writing before any work starts.

Any figure prefilled in the panel above is stated with the year it belongs to and can be changed. Rates and thresholds move; a calculator that asks you for the current one stays right, and one that hides a guess does not.

Case study 1
A Pricing Study That Started With Who Does What
Functions, assets and risks decide which entity should earn the return, and the method follows from that rather than the other way round. Getting the sequence backwards is how a study fails on its first question.

Case study 2
Choosing Between Methods on the Evidence
A comparable uncontrolled price is the strongest method where one genuinely exists, and reaching for it where it does not is weaker than a properly applied alternative. The choice is documented with the reasons for rejecting the others.

Case study 3
Withholding Reduced by the Right Article
Dividends, interest and royalties each have their own article and their own rate, and the payer applies whichever it is satisfied of. Establishing entitlement before payment is what secures the lower rate at source.

Case study 4
A Canadian Working in the US on a Work Visa
Immigration status and tax residence are different tests, and a visa says nothing about which country taxes the salary. The file fixes residence, applies the employment article, and sequences the two returns so the credit lands where it is usable.

Case study 5
An IRS Notice for a Year the Client Believed Was Settled
Most notices are proposals rather than assessments, and they carry a response window that is shorter than it looks. The engagement reads what is actually being proposed, gathers the support, and replies inside the window with the position rather than a request for time.

Case study 6
Tax Deducted When Buying From an NRI
Withholding on a sale by a non-resident is applied to the sale value rather than to the gain, so it routinely exceeds the tax due. A lower-deduction certificate obtained before completion avoids locking the difference up.

Case study 7
Treaty Relief Claimed on a Cross-Border Estate
The estate article can extend a proportionate credit where the two systems would otherwise both tax the same asset. Claiming it requires a valuation and a disclosure the estate may not expect to make.

Case study 8
Residency Changed Mid-Year and Both Returns Assumed a Full One
A move part-way through a year produces two part-year positions, not two full ones. The engagement establishes the date residence actually changed, allocates income either side of it, and amends whichever return was filed on the wrong footing.

Core International & Cross-Border Tax Services
International Tax Planning & Advisory
Strategy and compliance for income, assets and families spread across borders.
One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.
U.S. & Cross-Border Tax Returns
Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.
Expat & Emigration Tax
The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.
Non-Resident Canadian Tax
Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.
Transfer Pricing & BEPS
Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.
Tax Treaties & Withholding
Relief is only as good as the paperwork claiming it — we build treaty positions that survive review on both sides.
Cross-Border Estates & Trusts
Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.
Global Investments & Reporting
Information returns carry the sharpest penalties — $25 a day whether or not any tax is owing. We keep them clean and on time.
Cross-Border Corporate Tax
Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.
India Tax for NRIs & Returning Residents
The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.
Canadian Tax with a Foreign Element
Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.
UAE Tax for Expats & Their Home Country
A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Global E-commerce & Marketplaces
Cross-border tax for sellers shipping worldwide: marketplace withholding, foreign registrations and inventory nexus handled before they become audits.
Marketplaces withhold, remit and report in their own right, so the tax position of a single sale is decided by where the stock sat, where the buyer was and which platform collected — not by where the company is registered. We reconcile the platform's own filings against the returns before either is submitted.
