Relief from Royalty vs Cost Approach
Comparing income-based RFR with cost-based valuation for intangible assets. When each method provides the most reliable fair value estimate.
Introduction
The Relief from Royalty (RFR) method and the Cost Approach represent two fundamentally different philosophies for valuing intangible assets. RFR derives value from the income an asset generates — specifically, the royalty payments the owner avoids by owning the asset outright. The Cost Approach estimates what it would cost to recreate or replace the asset from scratch, adjusted for obsolescence.
These methods will often produce different values for the same asset, and that divergence is informative. When a technology platform costs £2 million to develop but saves its owner £8 million in licensing fees over its useful life, the gulf between Cost Approach and RFR tells you something important about the asset's economic contribution.
Understanding when each method is appropriate — and when to use one as a cross-check against the other — is a core competency for valuation practitioners working in purchase price allocation and impairment testing.
How Relief from Royalty Works
RFR values an intangible by capitalising the hypothetical royalty payments the owner saves. The steps are:
- Forecast revenue attributable to the asset over its remaining useful life
- Select a royalty rate based on comparable licensing transactions
- Calculate pre-tax royalty savings (revenue multiplied by royalty rate)
- Deduct tax and apply a tax amortisation benefit where applicable
- Discount to present value at an appropriate risk-adjusted rate
The method's strength is its direct connection to market-observable data. When comparable licensing transactions exist, the royalty rate provides an anchor that is independently verifiable. This makes RFR highly defensible in audit and regulatory contexts.
How the Cost Approach Works
The Cost Approach estimates fair value based on what a market participant would pay to acquire a substitute asset of comparable utility. Two variants are commonly used:
Reproduction cost estimates what it would cost to create an exact replica of the asset using current prices and techniques. This is appropriate when the specific form of the asset matters (e.g., a proprietary algorithm).
Replacement cost estimates what it would cost to create an asset with equivalent functionality, even if the design or implementation differs. This is more commonly used as it reflects how a rational market participant would think.
Both variants require adjustment for:
- Physical obsolescence — wear and deterioration (rare for intangibles)
- Functional obsolescence — loss of utility due to technological advancement
- Economic obsolescence — loss of value due to external market factors
The Cost Approach measures what an asset costs to create, not what it is worth in use. For highly profitable assets, cost-based values will typically be significantly lower than income-based values — and that gap represents the entrepreneurial profit or economic goodwill associated with the asset.
Side-by-Side Comparison
Methodology comparison
| Criterion | RFR | Cost Approach |
|---|---|---|
| Valuation philosophy | Income-based: value from economic benefit | Cost-based: value from reproduction or replacement |
| Best suited for | Revenue-generating IP with licensing analogues | Internally developed software, databases, workforce |
| Data requirements | Royalty rate benchmarks, revenue forecasts | Development cost records, labour rates, obsolescence |
| Reflects market value? | Yes — tied to income generation | Partially — cost is a floor, not a ceiling |
| Complexity | Moderate | Low to moderate |
| Audit defensibility | High when royalty comparables exist | High when cost records are verifiable |
| Key limitation | Needs comparable royalty data | May understate value of profitable assets |
When values diverge significantly
The gap between RFR and Cost Approach values is itself a meaningful data point:
| Scenario | Implication |
|---|---|
| RFR >> Cost | Asset generates substantial excess returns; income approach is more reliable |
| RFR ≈ Cost | Asset performs in line with development investment; both methods converge |
| RFR < Cost | Possible economic obsolescence; asset may not justify its development cost |
If the Cost Approach produces a higher value than the income-based methods, this is a red flag. It may indicate functional or economic obsolescence that should be reflected in the cost-based valuation through larger obsolescence adjustments.
Asset-by-Asset Guide
Assets best valued with RFR
- Trademarks and trade names — extensive licensing databases available
- Developed technology — technology licensing is a well-documented market
- Patents — patent licensing royalty rates are widely published
- Franchise agreements — franchise fee structures provide direct market data
Assets best valued with Cost Approach
- Internally developed software — development costs are well-documented; licensing analogues may not exist
- Databases and data assets — cost of data collection and structuring is quantifiable
- Assembled workforce — recruitment and training costs (though not separately recognisable under IFRS 3)
- Standard operating procedures and process documentation — replacement cost is the most practical approach
Choose RFR When
- Asset generates identifiable revenue
- Comparable licensing transactions exist
- Fair value is expected to exceed cost
- Market participant would license rather than build
Choose Cost Approach When
- No market transactions or royalty data
- Asset is internally developed with documented costs
- Asset saves costs rather than generating revenue
- As a reasonableness floor for income-based values
Practical Example: Valuing a Proprietary Data Platform
A mid-market analytics company has built a proprietary data platform over four years. The platform:
- Cost £3.2 million to develop (fully documented labour, infrastructure, and licensing costs)
- Generates £6.5 million in annual revenue from data subscriptions
- Has comparable data licensing agreements at 8%–12% of revenue
Cost Approach: Replacement cost of £3.2 million, less 20% functional obsolescence (some components built on now-superseded frameworks) = £2.56 million.
RFR: Revenue of £6.5 million multiplied by 10% royalty rate, projected over 8-year useful life, discounted at 14% = £4.1 million.
The £1.5 million gap reflects the entrepreneurial profit — the economic return above cost that the platform generates. In this case, RFR produces the more reliable fair value because the asset demonstrably generates income well above its replacement cost, and royalty benchmarks are available.
This pattern — Cost Approach as floor, RFR as primary — is typical for technology assets in acquisition contexts. The Cost Approach remains valuable as a sanity check: if RFR produced a value below the Cost Approach, it would warrant investigation into whether the royalty rate is too low or the useful life too short.
Common Mistakes to Avoid
Practitioners frequently make errors when choosing between or applying these methods:
- Using the Cost Approach as a shortcut when income data is available but harder to obtain. The Cost Approach is simpler, but simpler is not always more appropriate.
- Ignoring obsolescence adjustments in the Cost Approach. Raw reproduction cost without functional and economic obsolescence adjustments overstates value for any asset that is not brand new.
- Selecting non-comparable royalty rates for RFR. A royalty rate from a different industry, asset maturity, or transaction type can produce misleading results.
- Failing to reconcile when both methods are applied. If the methods produce significantly different values, one of them contains a flawed assumption that needs investigation.
Decision Framework
1. Does the asset generate revenue?
If yes, an income-based approach (RFR) is likely more appropriate. If the asset saves costs without direct revenue attribution, the Cost Approach may be primary.
2. Are royalty benchmarks available?
Search licensing databases (RoyaltyStat, ktMINE) for comparable transactions. If credible benchmarks exist, RFR is strongly favoured.
3. Are development costs documented?
Well-documented cost records make the Cost Approach feasible. Incomplete records weaken the method's reliability.
4. Use the secondary method as a cross-check
Whichever method is primary, use the other as a reasonableness test. Significant divergence warrants investigation.
Conclusion
RFR is the stronger method when the asset generates revenue and licensing benchmarks exist — it directly captures the asset's economic contribution. The Cost Approach is the preferred primary method for assets with well-documented development costs but limited market data, and it serves as an essential floor value in virtually every valuation engagement.

The Bottom Line
The Cost Approach tells you what an asset costs to build. RFR tells you what it is worth. For high-performing intangible assets, these numbers will differ substantially — and the income-based value is almost always the more reliable indicator of fair value in a transaction context.
