Gamma Plus gives 1,500 credits a month and Pro gives 4,000. On Gamma's published rates, Plus covers roughly 5 to 50 twelve-slide decks with Standard or Advanced images, 40 or more text-only decks, but only 2 to 5 with Premium images throughout. Pro holds about 2.7 times as much, plus custom branding and analytics.
Gamma does not publish a price per deck, so the numbers below are conversions from the per-card and per-image credit costs in its developer documentation, which I fetched this month. They are estimates for the standard generation route, labelled as such, and you should confirm with a test deck in your own account. Use them to pick a plan, then check your real balance after the first week.
What each plan gives, in one table
These are the figures on Gamma's pricing page, USD, per seat per month on annual billing. The page says annual billing saves up to 28 per cent against paying monthly.
| Plan | Price (billed annually) | Monthly credits | Notable limits and extras |
|---|---|---|---|
| Free | $0 | 400 at sign-up, no refill | Up to 10 slides per prompt, Gamma branding, export to PDF, PPTX, PNG and Google Slides |
| Plus | $9 a month ($108 a year) | 1,500 | Up to 100 slides per prompt, branding removed, advanced AI image models |
| Pro | $18 a month ($216 a year) | 4,000 | Premium AI image models, custom branding, detailed analytics, advanced sharing, up to 10 custom domains |
| Ultra | $90 a month ($1,080 a year) | 20,000 | Most advanced text, image and video models, up to 100 custom domains, early access to new features |
| Business | $40 per member a month, billed annually (help centre) | 10,000 per member | SSO, every image model, 100 custom domains, AI training locked off for the workspace, seats bought upfront |
Rollover is the detail that changes the sums. Unused credits roll over up to twice the monthly amount, so Plus can hold 3,000 and Pro 8,000. Credits you buy as extra are tracked separately, do not count towards that cap and, according to Gamma's help centre, do not expire while you stay subscribed. If your usage swings between busy and quiet months, a plan that seems too small on average may be fine. One note for anyone reading older advice: some pages still show Plus at 1,000 credits, but Gamma's pricing page now lists 1,500.
How a credit turns into a slide
Gamma's help article says generation is metered per slide and per image, that longer or more complex generations use more, and that more advanced models can cost more. It publishes no fixed rate. Its developer documentation, which covers the API and may differ from the app, gives ranges for a standard generation:
- Text: 1 to 3 credits per card, depending on the text model Gamma selects.
- Images: Standard models 2 to 15 credits each, Advanced 20 to 33, Premium 34 to 75, and Ultra 30 to 125.
The same page gives example costs: 10 cards and 5 basic-model images come to about 20 to 60 credits, 20 cards with 15 premium images about 320 to 1,070, and 30 cards with 30 ultra images about 930 to 3,900. Editing with Gamma's agent or adding cards with AI uses credits as well, and a small request such as changing one slide generally costs less than regenerating the whole deck.

Buy nowCredits converted into decks: the main sum
Take a twelve-card client deck, a common length for a proposal or a monthly update. Four versions, depending on the images, using the ranges above and rounding down so you do not over-promise:
| Deck type | Credits per deck (estimate) | Decks on Plus (1,500) | Decks on Pro (4,000) |
|---|---|---|---|
| A. Text only, no AI images | 12 to 36 | 41 to 125 | 111 to 333 |
| B. 8 Standard-model images | 28 to 156 | 9 to 53 | 25 to 142 |
| C. 8 Advanced-model images | 172 to 300 | 5 to 8 | 13 to 23 |
| D. 8 Premium-model images | 284 to 636 | 2 to 5 | 6 to 14 |
The arithmetic is 12 cards at 1 to 3 credits plus 8 images at the stated range, and then the plan's credits divided by the result, rounded down. For deck C, for example, 8 images at 20 to 33 credits is 160 to 264, plus 12 to 36 for the cards, giving 172 to 300. Plus's 1,500 divided by 300 is 5, and divided by 172 is 8.7, hence "5 to 8".
The wide ranges are the lesson. A Plus plan covers dozens of decks if you use Standard images or none, and only a handful if you insist on premium art for every slide. Image model choice decides your deck count more than the plan does. The Free plan's 400 credits, by the same sums, produce about 2 to 14 type B decks, which is enough to test your own content before paying.
A test that gives you your own number
Because the figures above are estimates, spend ten minutes finding yours. Use the Free plan or the first day of a paid plan.
- Note your credit balance.
- Generate a deck from one real brief, at the length and image style you would normally use.
- Note the balance again. The difference is what that deck costs.
- Make three typical edits: change one slide with AI, add two cards, and swap one image. Note the cost of each.
- Repeat with a second, different brief, and average the two.
A prompt like this is a fair test brief:
Create a 10-slide proposal deck for a garden design service pitching a hotel's courtyard refresh.
Sections: the brief, our approach, three design options, timeline, cost range, next steps.
Use plain language, no stock phrases, and use Standard image models only.Record the credits, then do the same with the premium image setting to see the difference. That second figure is the one that shows how fast credits go. Remember to count the edits, because real decks are never finished on the first generation.
Plan choice by how a small business actually works
Four patterns cover most small businesses. The figures use the estimates above and are illustrations, not measured results.
The occasional pitcher: Free, then Plus
A small optician's practice makes one supplier presentation a quarter and one staff training deck. That is a few thousand credits a year at most. Free's 400 credits cover a trial, and a Plus plan taken monthly for the one busy month, rather than annually, is the cheaper way to remove the Gamma branding for a client-facing deck.
The weekly maker: Plus is enough for most
A freelancer who builds four client decks and eight internal slides a month, each about 12 cards with Standard images, uses perhaps 12 decks × 100 credits, around 1,200. That fits inside Plus's 1,500, with rollover to absorb a busy month. The annual price of $108 is about $9 per month for a tool you use weekly.
The image-heavy team: Pro for credits, branding and analytics
A pet shop's marketing person wants brand-consistent social graphics, product decks and web pages with Advanced images. At around 250 credits a deck and 20 decks a month, that is 5,000 credits, more than Pro's 4,000. Rollover helps in quiet months but not for a steady 5,000. They might either move to Pro and drop the image tier, or buy extra credits: Gamma's help centre lists top-ups from $6 for 1,500 credits at one flat rate, so the missing 1,000 a month costs about $4. Pro's real extras here are custom branding and analytics, which matter if clients open shared links and you want to see which pages they read.
The agency or heavy video user: look at Ultra or Business
Ultra's 20,000 credits and video models only make sense if you generate a lot of premium images or video. For a small team, test Pro first and use extra credit purchases for the occasional heavy month. If you have several seats, ask Gamma about Business, since its 10,000 credits per seat is a team arrangement with seats bought upfront.
For wider guidance on whether Gamma is worth paying for at all, Is Gamma worth paying for? Credits, plans and real business uses covers the business cases, and Gamma app pricing: is the paid plan worth it for client decks looks at the price against doing it by hand.
How to make credits last longer
- Choose the image model on purpose. Gamma shows the credit cost of an image model before you generate. Use Standard or your own photos by default and save Advanced and Premium for the title slide and one hero image.
- Edit a slide, do not regenerate the deck. Gamma's help article says changing one slide generally costs less than regenerating the whole thing. If the structure is right, fix the weak slide.
- Start from your own notes. A detailed outline gives a better first generation, so fewer regenerations. Build a client proposal from your own notes shows how to prepare them.
- Bring your own images. Logos, product photos and screenshots cost nothing in credits and look more like your business than generated art.
- Keep text decks text. A weekly internal update does not need images at all. At 12 to 36 credits it is almost free.
The expensive habit: regenerating the whole deck three times
A pattern to watch for is the founder who dislikes the first result, rewrites the prompt and regenerates the full deck, three or four times, each with premium images. At 284 to 636 credits per attempt, four attempts is 1,100 to 2,500 credits, which is a Plus plan's whole month for one deck. It shows up as an unexpectedly low balance on day ten.
The fix is a routine: generate once at the cheapest image setting, judge the structure and text, and only then upgrade images on the few slides that need them. Treat the first generation as a draft of the outline, not the finished deck. Check your balance after each major step for the first month, until you know your normal usage.
Cost per deck in dollars, not credits
Credits are an awkward unit when you are deciding whether to pay. Convert them into dollars with the annual price divided by the credits in a year. Plus is $108 for 18,000 credits (12 × 1,500), which is $0.006 a credit, or $6 per 1,000. Pro is $216 for 48,000 credits, which is $0.0045 a credit, or $4.50 per 1,000. Ultra is $1,080 for 240,000 credits, $0.0045 a credit again. Pro's credits are therefore cheaper per credit than Plus's, though you only gain if you would actually use them. Bought top-ups, at $6 per 1,500, work out at $0.004 a credit, so for an occasional busy month a top-up on Plus is cheaper than moving up a plan.
Apply that to the four deck types, using the middle of each range. Type A at 24 credits costs about $0.14 on Plus. Type B at 92 credits costs about $0.55. Type C at 236 credits costs about $1.42. Type D at 460 credits costs about $2.76. Against a freelance designer, or against two hours of your own time, those are tiny figures. The cost of Gamma is rarely the credits. It is the plan fee you pay whether or not you make a deck, which is why the number of decks you make matters more than their credit cost.
A six-person consultancy's month, line by line
An illustrative ledger for a six-person consultancy where one person produces all the decks on a single Plus seat (Gamma charges per seat, so anyone else who edits needs their own). The numbers are made up but follow the estimates above.
Opening balance (with rollover): 1,500
Week 1: 2 client proposals, 14 cards, 8 Standard images each: about 2 x 110 = 220
Week 1: edits (one slide rewrite x 6, two cards added x 4): about 60
Week 2: monthly update deck, text only: 25
Week 2: 1 pitch deck with Advanced images on 4 slides: 190
Week 3: 3 internal training decks, text only, 12 cards: 3 x 25 = 75
Week 4: 1 proposal regenerated twice after a client changed scope: 2 x 110 = 220
Total used: about 790
Closing balance: about 710 (rolls over, cap 3,000)
Seat cost: $9 a month on the annual planThat month used about half the credits, so Plus is comfortable. Pro would add nothing here except branding options and analytics, which this consultancy would only need if clients view decks through shared links.
Which plan for how many decks a month
As a rule of thumb, not a rule, assuming 12-card decks and Standard images (deck type B, about 28 to 156 credits, call it 100 for planning):
| Decks a month | Credits needed (with 30% for edits) | Plan that covers it |
|---|---|---|
| 1 to 3 | 130 to 390 | Free for a trial, then Plus if you need the branding gone |
| 5 to 8 | 650 to 1,040 | Plus |
| 12 to 14 | 1,560 to 1,820 | Plus with a quiet month's rollover, otherwise Pro |
| 20 | 2,600 | Pro |
| 20 with Advanced images | about 6,000 or more | Pro plus extra credits, or Ultra |
If your decks use Advanced or Premium images, divide those deck counts by three to five. The image tier moves you up the plans faster than the number of decks.
Before and after: a brief that cost less and read better
A vague brief produces a vague deck and a regeneration. Compare two briefs for the same pet shop wholesale pitch.
The vague brief: "Make a presentation about our wholesale pet food range for new stockists, make it look good with lots of images." A model fills the gaps, picks a style, and adds an image to nearly every card. The first result is generic, and the owner regenerates it twice. With Premium images on about nine cards, each attempt costs roughly 320 to 700 credits, so the three attempts use about 950 to 2,100.
The specific brief: "10 slides for independent pet shops considering stocking our dry dog food. Slides: who we are, range of 6 products with weights and price bands, margin example for a 12 kg bag, delivery terms, minimum order, how to order. Text only except one product photo supplied by us. Plain tone." With no generated images, ten cards at 1 to 3 credits come to about 10 to 30, and the first result needs two edits, not a regeneration. The deck is also better because the structure came from the person who knows the business.
Free plan: what you can learn from 400 credits
The Free plan is a real testing tool, not just a teaser, as long as you plan your 400 credits. They do not refill, so spend them on decisions you need to make.
- One 10-slide deck from a real brief at Standard images: about 30 to 150 credits, depending on the images.
- The same brief at the next image tier, to see the difference in cost and look.
- Three edits: a rewrite, an added card, a swapped image, noting the cost of each.
- An export to PowerPoint and PDF, which is free of credits, to check how it looks in the software your clients use.
Free decks carry Gamma branding and are limited to 10 slides per prompt, so you cannot test a 20-slide proposal. For that, take Plus for one month and cancel if it does not suit.
A note on data and ownership
If your decks contain client names, prices or unannounced plans, check one setting before you paste them in. Gamma's help centre says that on individual plans (Free, Plus, Pro and Ultra) your data is allowed to be used to train its AI models by default, and you can opt out at any time under Settings, then the Data Controls tab. On Business and Enterprise workspaces training is switched off and locked. Turning it off on an individual plan takes a minute, so do it on day one.
What to do when the balance runs out
On a paid plan, Gamma's help article says you can still use non-AI features and edit manually, so a deck in progress is not locked. For the AI actions, you have three options: wait for the refill, buy more credits, or move up a tier. Gamma's help centre says top-ups start at $6 for 1,500 credits with no bulk discount, that purchased credits never expire while you are subscribed, and that after a cancellation they last one year. Auto-recharge is off by default and only a workspace admin can switch it on. Credits refresh on your billing date, not the first of the month. On Free there is no refill and you cannot buy credits, so earning more means referrals or upgrading.
A sensible buffer: when your balance drops below one deck's cost, finish edits by hand and plan the next generation for the refill date, instead of paying for a rush purchase for one pitch.
A quick checklist before paying
- Run the test above and write down credits per deck and per edit.
- Count the decks you really made last month, not the ones you meant to make.
- Multiply: decks × credits per deck, then add 30 per cent for edits.
- Pick the cheapest plan whose credits, with rollover up to double, cover that number.
- Decide whether you need Gamma branding removed. If client-facing decks are the point, that alone justifies Plus.
- Choose monthly or annual: monthly for a one-off job, annual if you will use it all year.
- Put a reminder in the calendar to read your balance in week two.
If your clients ask for PowerPoint files, check how the export behaves before you commit, which exporting Gamma to PowerPoint and fixing the formatting covers. Gamma lists export to PDF, PPTX, PNG and Google Slides on the Free plan.
Questions about Gamma credits and plans
Do unused Gamma credits roll over?
Gamma's help centre says unused plan credits roll over up to double the plan size. A Plus plan with 1,500 monthly credits can therefore hold up to 3,000. Credits you buy separately do not count towards that cap. The Free plan's 400 credits at sign-up do not refill.
What happens when I run out of credits on a paid plan?
According to Gamma's help article, on a paid plan you can still use the non-AI features and edit manually. AI actions such as generating slides, adding cards with AI and creating images need credits, so you either wait for the monthly refill or buy more.
Is annual billing worth it for Gamma?
Gamma's pricing page says annual billing saves up to 28 per cent. On Plus, $9 a month billed annually is $108 a year. If you will use it for at least a year, annual is cheaper. If you only need it for a one-off pitch, monthly billing avoids paying for months you will not use.
Can I see how many credits a deck used?
Not directly. Gamma's help centre says it does not yet show a credit history for each presentation or action. It does show the credit cost of an image model before you generate, and costs are metered per slide and per image, so note your balance before and after a representative deck to get your own figure.
