The terminal growth rate in music catalog DCF models, g, is the assumed long-run annual growth rate applied to a catalog’s cash flows beyond the explicit forecast horizon. In the Gordon Growth model:

Gordon Growth Model

Terminal Value = CF(n+1) / (r − g)

Because the terminal value often represents 50% to 70% of total catalog value, g has an outsized influence on the output. A half-percentage-point change can shift the valuation by 10% or more, making it one of the most consequential assumptions in the entire model.

Why Inflation Is the Right Anchor for the Terminal Growth Rate, g

The right anchor for g is inflation: either the central bank’s inflation target or the long-run historical average inflation rate for the catalog’s primary currency.

By the time the terminal value kicks in, typically around year 10 to 15 of the projection, the explicit decay modeling has already accounted for the steepest portion of earnings decline. What remains is the stabilised tail: the long-run royalty income the catalog will generate for the remaining life of its copyrights.

At this point, the catalog’s earnings are no longer a function of the individual track’s lifecycle. They grow or decline with the music industry as a whole. Subscription prices adjust, new markets monetise, consumer spending rises with the general price level. Over the very long term, the nominal growth of the industry should track inflation, and so should the catalog’s stabilised income.

A g set at the inflation target (approximately 2% in most developed markets) represents the neutral assumption: the catalog’s stabilised earnings maintain their real value in perpetuity. This is the default. Deviating from it in either direction requires a specific, defensible rationale.

When the Terminal Growth Rate Can Exceed Inflation

A terminal growth rate above inflation implies the catalog will grow faster than the general price level in perpetuity. This is a high bar. Two cases have merit:

Publishing rights have a reasonable case. A composition can generate new income from cover recordings, sync placements, and emerging use cases (user-generated content platforms, AI-adjacent applications) without requiring the original recording. This optionality may justify g modestly above inflation, on the order of 0.5 to 1.0 percentage points.

Emerging market exposure can be relevant if the catalog earns significantly in territories where streaming penetration is still early. However, this near-term growth driver is better captured in the explicit forecast period than embedded in a perpetuity assumption.

Any g above 3% should be treated with skepticism. It implies sustained real growth for a specific catalog in perpetuity, which requires an extraordinary thesis.

When the Terminal Growth Rate Should Be Below Inflation

A g below inflation implies the catalog’s real earnings will erode over time. This can be justified in specific circumstances:

Copyright expiry approaching within the projection horizon for material works. The perpetuity assumption underlying the Gordon Growth formula begins to break down when meaningful rights are set to expire.

Structural headwinds specific to the catalog: a genre in permanent decline, a rights type with diminishing relevance, or a territory mix skewed toward markets with contracting music consumption.

A g of 0% means nominal earnings are flat in perpetuity, which represents roughly a 2% real decline annually. This is a meaningfully conservative assumption and should only be used when there is a specific reason to believe the catalog will underperform inflation indefinitely.

The r-g Spread: How It Drives Terminal Value in Music Catalog DCF

The terminal value is inversely proportional to the spread between the discount rate and g. As this spread narrows, the terminal value increases rapidly.

At r = 10% and g = 2%, the implied terminal multiple is 12.5x. At g = 3%, it is 14.3x. At g = 4%, it is 16.7x. The jump from g = 2% to g = 4% increases the terminal value by over 30%.

Two practical implications follow. First, r and g must be set in relation to each other. An analyst who uses a low discount rate and a high growth rate is double-counting optimism. Second, the implied terminal value multiple (1 / (r − g)) should be tested against observable transaction multiples. Chapter Two’s analysis of catalog acquisitions, across more than 100,000 catalogs and $2 billion in royalty data processed, shows that implied terminal multiples significantly above observed transaction multiples are almost always the result of an r-g combination that is too aggressive. If your model implies a multiple significantly higher than what comparable catalogs have traded for, the r-g combination needs revisiting.

Current streaming market growth rates of 8% to 10% are near-term adoption trends, not perpetuity rates. By the time the terminal value kicks in, those trends will have moderated. g should reflect the long-run steady state and that steady state is anchored to inflation.

Common Terminal Growth Rate Errors

Using near-term streaming growth as g. Current streaming growth of 8% to 10% is a near-term adoption trend. Embedding it in a perpetuity assumption produces a structurally inflated terminal value.

Not stress-testing the r-g spread. Because terminal value represents 50–70% of catalog value, a sensitivity table showing terminal value at g = 1%, 2%, and 3% (combined with a range of discount rates) should be a standard output of any DCF model. A valuation that changes by more than 25% across a reasonable sensitivity range deserves scrutiny.

Ignoring copyright duration. For catalogs where material works will enter the public domain within the projection horizon, the Gordon Growth formula’s perpetuity assumption breaks down. Terminal value should be adjusted to reflect a finite income stream.

Frequently Asked Questions

What is the Gordon Growth model and how is it used in music catalog valuation?

The Gordon Growth model calculates terminal value as CF(n+1) / (r − g), where CF(n+1) is the first cash flow beyond the explicit forecast period, r is the discount rate, and g is the assumed long-run growth rate. In music catalog DCF valuation, it is used to estimate the present value of royalty income beyond the explicit projection horizon, typically year 10 to 15, where individual track decay has already been modeled and what remains is the stabilised long-run earnings tail. Because the terminal value produced by the Gordon Growth model often represents 50% to 70% of total catalog value, the choice of g has an outsized effect on the output.

What terminal growth rate should be used for music catalog DCF?

The standard anchor is the inflation target for the catalog’s primary currency, which is approximately 2% in most developed markets. This represents the neutral assumption that the catalog’s stabilised earnings maintain their real value in perpetuity. Deviating above or below this requires a specific, defensible rationale tied to the catalog’s rights type, territory mix, or genre.

Why does the terminal growth rate have such a large impact on music catalog valuation?

Because the terminal value typically represents 50% to 70% of total catalog value in a DCF model. Music copyrights last up to 70 years after the author’s death, meaning a large portion of a catalog’s total income lies beyond the explicit forecast horizon. Even a 0.5 percentage point change in g can shift total catalog value by 10% or more.

Can the terminal growth rate be higher than inflation for music catalogs?

Yes, but selectively. Publishing rights have the strongest case. A composition can generate income from cover recordings, new sync placements, and emerging platforms without requiring the original recording, which provides an optionality argument for modest above-inflation growth (0.5–1.0 percentage points). Master recordings have a weaker case. Any assumption above 3% implies sustained real growth in perpetuity and requires an extraordinary, documented thesis.

How should the terminal growth rate and discount rate be used together?

They should be considered jointly rather than independently. The terminal value is driven by the spread between r and g: as that spread narrows, terminal value increases sharply. A model that uses a low discount rate alongside a high g is double-counting optimism. The implied terminal multiple (1 / (r − g)) should always be checked against observable transaction multiples as a sanity test.
