GPT Store Custom GPT Income Estimator & Revenue Calculator

Estimate your monthly and annual income from GPT Store revenue-share payouts, premium subscriptions, and consulting deals built around your custom GPTs.

GPT Store Income Formula

We combine OpenAI's GPT Store revenue-share program with two common alternative monetization paths: premium subscriptions outside ChatGPT and B2B consulting work that custom GPTs generate as leads.

Weekly Conversations per GPT = Monthly Conversations per GPT ÷ 4.345
Revenue-Share Eligible = Weekly Conversations per GPT ≥ 25
Store Revenue per GPT = Monthly Conversations per GPT × Payout Rate per Conversation (if eligible, else $0)
Total Store Revenue = Store Revenue per GPT × Number of Published GPTs
Subscription Revenue = Paying Subscribers × Monthly Subscription Price
Consulting Revenue = Consulting Clients × Average Monthly Retainer
Total Monthly Income = Total Store Revenue + Subscription Revenue + Consulting Revenue
Total Annual Income = Total Monthly Income × 12

OpenAI has never published an official payout formula. The default $0.03-per-conversation rate and 25-conversations-per-week eligibility threshold reflect figures widely reported by GPT Store creators and industry guides — actual store payouts vary by engagement quality, region, and OpenAI's undisclosed algorithm. Most builders earning meaningful income rely on subscriptions or consulting rather than store payouts alone.

Operational Guide

How to Use the GPT Store Custom GPT Income Estimator

1

Enter average monthly conversations per GPT

Use ChatGPT's GPT analytics (or an estimate) for how many conversations one of your published GPTs receives per month.

2

Set the number of published GPTs

If you operate multiple GPTs with similar traffic, multiply your revenue-share earnings across all of them.

3

Adjust the payout rate per conversation

The default is $0.03, based on figures reported by creators. Lower it for a conservative estimate or raise it if your GPT serves high-value Plus/Team users.

4

Add subscription and consulting revenue (optional)

Enter paying subscribers and price for any premium tier you sell outside ChatGPT, plus any consulting clients your GPT generates as leads.

5
