Metrics and Valuation Methodology#
Model version: 1.0 | Effective: July 13, 2026 | Last reviewed: July 13, 2026
This page explains how Romarket labels marketplace information and how the valuation calculator produces an estimate. The calculator is a heuristic planning tool, not an appraisal, fairness opinion, offer, or prediction of a completed sale.
Evidence labels used on Romarket#
Romarket separates facts and estimates by source:
| Label | Meaning | Important limitation |
|---|---|---|
| Roblox-sourced metric | Public experience data fetched from Roblox | Availability and definitions depend on Roblox's interfaces |
| Seller-provided metric | Revenue, retention, engagement, or proof supplied by a seller | Not independently audited merely because it appears on a listing |
| Asking price | The amount a seller requests | Not evidence that a buyer paid that amount |
| Reported transaction | A figure attributed to a named publication or party | May be estimated, undisclosed, or unconfirmed; read the attached caveat |
| Romarket model assumption | A value chosen by the calculator model | Not an observed market average or completed-sale comparable |
Buyers should cross-check public Roblox metrics, inspect seller-provided evidence, and use appropriate legal and financial advisers for a material acquisition.
Calculator formula#
The simple calculator uses this formula:
Estimated value = monthly USD revenue input × genre assumption
The monthly revenue input should use a consistent trailing period and represent USD revenue attributable to the experience before operating costs and taxes. It should not mix player spending, raw Robux, one-time transaction proceeds, and developer receipts as if they were the same measure.
Version 1.0 uses these assumptions:
| Genre | Model assumption |
|---|---|
| Roleplay | 14x monthly revenue |
| Tycoon | 12x monthly revenue |
| Simulator | 10x monthly revenue |
| Fighting | 8x monthly revenue |
| Obby | 6x monthly revenue |
| Other | 8x monthly revenue |
These are Romarket's directional model inputs. They were not estimated from a statistically representative dataset and should not be described as typical market multiples.
Romarket completed-sale records used to calibrate version 1.0: 0. Reported press transactions and live seller asking prices were not treated as completed-sale training data for these genre assumptions.
Advanced-mode adjustment#
Advanced mode multiplies the genre assumption by an engagement factor. Each input adds at most one adjustment from its row:
| Input | Threshold | Added factor |
|---|---|---|
| DAU / MAU | 10% to under 20% | +10% |
| DAU / MAU | 20% to under 30% | +20% |
| DAU / MAU | 30% or more | +30% |
| D7 retention | 5% to under 10% | +5% |
| D7 retention | 10% to under 20% | +15% |
| D7 retention | 20% or more | +25% |
| Average session length | 10 to under 15 minutes | +5% |
| Average session length | 15 to under 30 minutes | +10% |
| Average session length | 30 minutes or more | +20% |
The maximum combined adjustment is 75%. The adjusted multiple is rounded to one decimal place before it is multiplied by monthly revenue. Missing or below-threshold engagement fields add no adjustment.
What the model does not account for#
The calculator does not directly value source-code quality, intellectual-property ownership, contributor claims, revenue concentration, operating expenses, tax, contracts, community assets, update workload, policy risk, or the terms and timing of a specific transaction. Genre is only a coarse proxy and can be a poor fit for an individual experience.
The result is a single heuristic point, not a confidence interval. A negotiated price can be materially lower or higher, and an experience may not sell at all.
Reported deals and future completed-sale data#
Romarket's valuation guide discusses publicly reported transactions with their stated caveats. A press estimate, gross player booking figure, developer revenue figure, seller asking price, and completed asset-sale price are different measures and should not be substituted for one another.
If Romarket later calibrates a model from completed transactions, it will publish a new version with the dataset window, inclusion rules, sample size, definitions, privacy safeguards, and material changes. Small samples will not be presented with misleading precision.
