Roblox Game Pass Calculator — Price & Earnings After Tax

Introduction

Pricing a Roblox game pass sounds straightforward until you account for the platform fee. List a pass at 100 Robux and you do not keep 100 — Roblox deducts roughly 30% on marketplace sales, leaving about 70 Robux per purchase. Price too low and weeks of development earn less than a single day's DevEx-eligible balance growth. Price too high and conversion drops. Creators need both directions of the math: gross list price to net earnings, and target net earnings back to required list price.

Certoflow's Roblox Game Pass Calculator shows marketplace fee, net Robux per sale, and a USD estimate via the standard Developer Exchange rate. Enter a list price to see what you earn, or enter desired net Robux to find the gross price you must charge. Everything runs client-side in your browser — no Roblox login, no sign-up, and no account data sent to a server.

For general marketplace tax math, see the Roblox Tax Calculator. To convert accumulated earned Robux to real currency, use the Roblox DevEx Calculator.

What this tool does

Two inputs drive the results:

Input	Purpose
Game pass list price (Robux)	Gross price before Roblox takes its cut
Desired net Robux per sale	Target Robux you want to keep after the fee

Three result cards update when you change the list price:

Card	Meaning
Marketplace fee (30%)	Robux retained by Roblox on the gross amount
You earn per sale	Net Robux credited after the fee
USD estimate (DevEx)	Approximate real-money value at the 2026 DevEx rate

A second output shows List price needed for your desired net Robux — the gross price required so you keep that amount after the 30% fee, rounded up to whole Robux.

Example: list price 100 R$ → fee 30 R$, you earn 70 R$, USD estimate $0.27 at $0.0038 per earned Robux. Desired net 70 R$ → list price needed 100 R$.

How it works

Certoflow applies a default 30% marketplace fee on game pass sales:

Fee = floor(gross × 0.30)
Received = floor(gross − fee)

To find gross list price for a target net amount:

Gross needed = ceil(net ÷ (1 − 0.30))
Gross needed = ceil(net ÷ 0.70)

For desired net 70 R$: ceil(70 ÷ 0.70) = 100 R$ list price.

The USD estimate multiplies net Robux by the standard DevEx rate of $0.0038 per earned Robux (July 2026 reference rate):

USD = net Robux × 0.0038

70 R$ net ≈ $0.27 USD before taxes, eligibility requirements, and Roblox program rules.

All arithmetic runs in JavaScript on your device. The calculator does not model Premium payouts, group fund splits, affiliate commissions, or regional pricing — only the standard marketplace fee on a single game pass sale.

Fee breakdown table

List price	Fee (30%)	You earn	USD estimate (DevEx)
49 R$	14 R$	35 R$	$0.13
100 R$	30 R$	70 R$	$0.27
250 R$	75 R$	175 R$	$0.67
500 R$	150 R$	350 R$	$1.33
1,000 R$	300 R$	700 R$	$2.66

Real-world examples

Pricing a VIP game pass

A developer wants players to pay for double XP and exclusive cosmetics. They decide 175 net Robux per sale is fair value. The calculator shows they must list the pass at 250 R$ gross. They compare against competitor passes priced at 199 R$ (139 net) and 299 R$ (209 net) to position in the middle.

Underpricing discovery

A new creator lists a pass at 50 R$ expecting meaningful earnings. The tool shows only 35 R$ net per sale — roughly $0.13 at DevEx rates. They raise the list price to 149 R$ for 104 R$ net and accept slightly fewer conversions.

DevEx milestone planning

A creator targets 30,000 earned Robux for DevEx eligibility. At 350 net per pass sale, they need roughly 86 sales — or fewer if they also sell developer products. They cross-check totals in the Roblox DevEx Calculator.

Comparing with the tax calculator

The Roblox Tax Calculator focuses on gross-in → fee → net-out with a fixed 700 R$ net reference row. This game pass tool adds desired-net pricing and USD estimates tailored to pass monetization workflows.

Common mistakes

Confusing purchased Robux with earned Robux. DevEx USD estimates apply to earned Robux from sales, not Robux you bought with real money. Only eligible creator earnings cash out.

Ignoring floor rounding. Roblox uses integer Robux. Fees and net amounts floor down; required gross prices ceil up. A spreadsheet that keeps decimals will disagree slightly.

Expecting 100% of list price. The 30% fee is standard for marketplace sales. Budget net earnings, not gross list price, when setting revenue goals.

Using DevEx rate as guaranteed income. DevEx requires minimum balances, Premium membership, tax documentation, and account standing. USD figures here are estimates — verify on official Roblox documentation.

Pricing without conversion context. 70 net Robux sounds substantial to players but equals roughly $0.27 at DevEx rates. Price for player value, not just Robux psychology.

Use cases

Game pass launch pricing — Set list price knowing exact net Robux and USD equivalent before publishing.

Sale and bundle planning — Model net earnings when temporarily discounting pass prices during events.

Revenue goal reverse math — Start from desired net per sale and find the minimum list price.

Educational content for dev communities — Teach new creators the fee structure before they publish their first monetized experience.

Cross-tool workflow — Chain with Roblox Tax Calculator for UGC items and Roblox DevEx Calculator for cash-out planning.

FAQ

What fee does Roblox take?

Marketplace sales typically incur a ~30% platform fee. You receive about 70% of the list price in Robux, with amounts floored to whole Robux.

How do I price to earn a specific Robux amount?

Enter your desired net Robux in the second field. The tool calculates the gross list price using ceiling math so whole-Robux pricing still nets your target after the fee.

What is the USD estimate?

It multiplies net Robux per sale by $0.0038, the standard DevEx rate as of 2026. Actual cash-out value depends on eligibility and current Roblox program terms.

Does this include Developer Exchange fees or taxes?

No. The USD line is a gross DevEx conversion estimate. Real payouts may involve tax withholding and program requirements.

Is this only for game passes?

The same 30% marketplace fee applies to many Roblox sales including developer products and UGC. Game passes are the most common use case for this calculator's pricing workflow.

Do I need to log into Roblox?

No. The calculator runs entirely in your browser with no Roblox account connection.

How does this differ from the Roblox Tax Calculator?

The Roblox Tax Calculator shows fee breakdown from gross Robux with a 700 net reference. This tool adds desired-net reverse pricing and per-sale USD DevEx estimates for game pass monetization.
