Transfer Pricing Calculator

This calculator estimates whether an intercompany transaction price is defensible under the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations by computing the same price three independent ways and checking whether your actual transaction value falls inside the resulting range. The Comparable Uncontrolled Price (CUP) method takes an observed market price for a similar transaction between unrelated parties and applies a comparability adjustment (positive or negative) for differences in volume, terms, or geography. The Cost Plus method grosses up the supplying entity's cost base by an arm's-length markup percentage — typically 15-40% depending on the function performed. The Resale Price method works from the other direction: it takes the price the buyer resells the goods for and backs out an appropriate gross margin, since a distributor's arm's-length compensation is the margin it retains, not the price it originally paid.

All three are named "traditional transaction methods" in Chapter II of the OECD Guidelines, the standard most tax authorities worldwide follow when evaluating whether related-party pricing meets the arm's-length principle. The calculator then takes the minimum, maximum, and simple average of these three method outputs as the arm's-length low, high, and median. If your actual transaction value falls outside that low-high range, the tool flags the transaction as at deviation risk and estimates a potential tax exposure: it multiplies the absolute dollar gap between your actual price and the median by your corporate tax rate, approximating what a tax authority might assess if it imputed the median price and taxed the resulting profit shift. This is a simplified illustration of the arm's-length principle, not a substitute for a full functional and comparability analysis — real transfer pricing studies typically use statistical ranges (like an interquartile range across many comparables) rather than three point-estimates, and the "best method" selection under the OECD Guidelines depends heavily on which method's data and assumptions are most reliable for the specific transaction, not simply which methods happen to be available.
