Income approach: relief from royalty, multi-period and single-period excess earnings, incremental cash flow, and contributory asset charges. Method selects the formula. Use for the income-approach arithmetic: relief_from_royalty for IP with observable royalty rates, and excess earnings (mpeem or single_period_excess_earnings) for the residual intangible. For a complete asset-specific valuation of customer, technology, IP or workforce assets, prefer the dedicated valuation_customer, valuation_technology, valuation_ip and valuation_human_capital tools. For royalty-rate inputs use valuation_royalty_analysis; for asset-specific income valuations use valuation_customer, valuation_technology, valuation_ip or valuation_human_capital; for cost or market indications use valuation_cost_approach and valuation_market_approach. Per method: relief_from_royalty needs revenue_projections + royalty_rate + discount_rate + tax_rate + useful_life (optional: tab_enabled); mpeem needs cash_flow_projections + contributory_asset_charges + discount_rate + tax_rate (optional: tab_enabled); single_period_excess_earnings needs normalized_earnings + contributory_asset_charges + capitalization_rate; incremental_cashflow needs cash_flows_with + cash_flows_without + discount_rate; contributory_asset_charges needs assets. cash_flow_projections and contributory_asset_charges must be period-aligned; cash_flows_with and cash_flows_without must be equal length. Only method is required; all other parameters are method-dependent — supply those the selected method names and omit the rest (defaults apply where defined). Rates and premiums are decimals (0.10 = 10%). Pure arithmetic: no I/O and no external calls, rounded to 2 decimals; parameters belonging to other methods are accepted and ignored. An unknown method, or a missing method-required parameter, returns an error instead of a value.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| method | string | yes | Formula to apply. Options: relief_from_royalty = PV of after-tax royalties avoided by ownership.; mpeem = PV of excess earnings after contributory asset charges.; single_period_excess_earnings = Capitalize one period of excess earnings.; incremental_cashflow = PV of cash flows with the asset minus without it.; contributory_asset_charges = Total contributory asset charges. |
| revenue_projections | array | no | Projected revenue per period t=1..n, in currency units. |
| royalty_rate | number | no | Royalty rate as a decimal (0.05 = 5% of revenue). |
| discount_rate | number | no | Per-period discount rate as a decimal (0.10 = 10%). |
| tax_rate | number | no | Marginal tax rate as a decimal (0.25 = 25%). |
| useful_life | integer | no | Useful life in years n (integer ≥ 1). |
| tab_enabled | boolean | no | Whether to include the tax amortization benefit in the result. |
| cash_flow_projections | array | no | Projected after-tax cash flows per period t=1..n, in currency units. |
| contributory_asset_charges | array | no | Contributory asset charge per period t=1..n, in currency units. |
| normalized_earnings | number | no | Single-period normalized earnings, in currency units. |
| capitalization_rate | number | no | Capitalization rate as a decimal (0.15 = 15%). |
| cash_flows_with | array | no | Cash flows per period with the asset, in currency units. |
| cash_flows_without | array | no | Cash flows per period without the asset, in currency units. |
| assets | array | no | Contributory assets, each {value, return_rate}. |
