Cost Per Image for AI Porn Generators, Calculated
List prices on adult AI tools are hard to compare because one site sells coins, another bills every 28 days, and a third caps images per day. The useful number is cost per usable image. This article shows how to calculate it from published prices, with worked examples, and where the math breaks. You must be 18 or older to use any of these services.
Why sticker price is not the cost
A $10 pack and a $20 subscription can both look cheap until you count how many keepable images you actually get. Failures, retries, higher-resolution upsells and video tiles change the result. Companion apps often include media tokens inside a chat plan, so people who only want stills subsidise features they never open. Studios that print a coin price on each tile make the unit cost clearer. For the broader pricing landscape, start with our AI porn generator pricing guide.
The method below works for both models. You only need three inputs: what you paid, how many credits that bought, and how many credits one successful image costs.
The formula
Use this every time:
- Price of the pack or plan in your currency.
- Credits in that purchase (coins, gems, tokens or dreamcoins).
- Credits per successful image for the action you actually run.
Then:
- Cost per credit = price ÷ credits.
- Cost per image = cost per credit × credits per image.
- Images from the purchase = floor(credits ÷ credits per image).
If the plan includes “unlimited casual” generations, treat the monthly fee as the numerator and your realistic monthly count as the denominator. Do not use the theoretical maximum unless you will hit it.
Mark anything you could not read on an official page as unverified and re-check at checkout. Prices move.
Worked example: GeneratePorn.ai coin packs
GeneratePorn.ai publishes one-time Coin packs and prints the Coin cost on each tile. Facts below were checked on its official site on 4 November 2026; confirm live numbers before you buy. Full pack list and notes are on our GeneratePorn.ai pricing page and in the GeneratePorn.ai review.
Published packs (card prices):
- 80 Coins for $4.99 (first purchase only)
- 150 Coins for $9.99
- 330 Coins for $19.99
- 730 Coins for $39.99 (labelled best rate on the site)
- 1,510 Coins for $74.99
- 3,310 Coins for $149.99
Published action costs that matter for stills:
- Undress photo: 17 Coins (first free)
- Photo sets: from 49 Coins
Using those figures, cost per Coin falls as packs get larger: about $0.067 on the 150-Coin pack, about $0.055 on the 730-Coin pack, and about $0.045 on the largest pack. That puts a 17-Coin undress at roughly $1.13 on the 150 pack and about $0.93 on the 730 pack. A 49-Coin photo set lands around $3.26 and $2.68 on those same packs. Crypto payments add 25% more Coins on the packs we checked, which lowers the unit cost further after network fees.
The first free image and first free undress make early tests free of charge. After that, the tile price is the budget. Coins never expire and nothing renews on the homepage model, which is why pay-as-you-go studios often win for light use. See also the best AI porn generators with no subscription.
Subscription plans: divide by real monthly output
Promptchan
Promptchan’s official upgrade page lists Plus at $14.99 every 28 days with 100 Gems, Premium at $23.99 with 400 Gems, and Pro at $33.99 with 800 Gems plus unlimited casual generations. Per-action Gem costs for premium styles were not published on the pages we read, so a precise Gem-based cost per image stays [unverified] until you check inside the account. On Pro, if you treat unlimited casual stills as the product and you make about 100 keepable images in a 28-day cycle, the fee works out near $0.34 each. At 300 images it drops near $0.11. If you barely open the generator, the same $33.99 is expensive per shot. Details sit on our Promptchan pricing page.
Venice.ai
Venice Pro is listed at $18 with up to 1,000 images a day on its own models, plus credit pricing where 100 credits equal $1 for some video routes. If you generate 100 images in a month on Pro, that is $0.18 each before any credit add-ons. At 500 images it is about $0.036. The daily cap only helps if you use it; most people will not. See the Venice.ai review.
OurDream and Candy AI
OurDream’s FAQ states $19.99 monthly or $119.88 yearly, with 1,000 dreamcoins included. How many dreamcoins one still costs was not clear on public pages when we checked [unverified], so run the formula inside the app before comparing. Candy AI describes monthly, quarterly and yearly plans with a shared token pool for chat, voice, image and video, but plan prices were not shown to logged-out visitors, so third-party dollar figures remain [unverified]. Companion plans are a poor basis for cost-per-image if conversation uses most of the allowance.
Hidden costs that change the number
- Retries. If one in three outputs is unusable, multiply your unit cost by 1.5.
- 28-day billing. Thirteen Promptchan cycles in a year raise the annual total above twelve calendar months. We cover that pattern in are annual plans worth it.
- Video tiles. A 79-Coin template is several undress edits. Mixing video into an “image budget” inflates the average.
- Top-ups. Small packs have worse Coin rates; a low headline price can mean a higher cost per image.
- Expired access. Some subscriptions leave credits that cannot be spent without an active plan. Spend them before you cancel; our cancellation guide walks through timing.
- Refunds. Strict windows mean a bad first batch can become a sunk cost. Compare policies in refund policies compared.
A fair way to compare two tools
- Pick the same output: one keepable still at similar quality, not a video versus an image.
- Use the pack or plan you would actually buy, not the theoretical best rate on a pack you will never fill.
- Count only successful keeps after your usual retry rate.
- Ignore free first generations after the first week, unless you only ever need one test.
- If one tool bundles chat you will not use, prefer a studio’s per-tile price for the image-only use case.
For privacy-minded buyers, payment method also matters. Crypto can change effective Coin rates on GeneratePorn.ai but adds network fees; card billing and statement names are covered in our notes on paying with crypto and discreet billing.
When a higher sticker price is cheaper
Heavy daily stills often favour a flat plan with a high or unlimited casual cap, because the monthly fee is spread thin. Occasional users usually pay less overall on one-time Coins that never expire, even when each image looks pricier on paper. Video-heavy workflows need a separate per-second or per-clip calculation; mixing them into an image average hides the real spend.
Always re-check the live tile or Gem cost. The arithmetic above is only as good as today’s published numbers.
Safety and honesty notes
Only generate fictional adults. Do not create non-consensual images of real people. Platforms forbid under-18 content; follow that rule without exception. Affiliate links on this site use our standard GeneratePorn.ai tracking pattern where we recommend that product; other tools are covered for comparison and may have no affiliate link.
