AI 3D Credit and Cost Calculator
An AI 3D credit and cost calculator with plan presets or your own price and credits. Includes the formulas, dated per-credit prices and a worked example.

The two views differ when you underuse a plan. Preset plans use monthly prices read 2026-11-08. Check the vendor page before relying on them. Your inputs stay in this browser.
This is the calculation behind the cost of AI 3D assets: it turns credits per attempt, attempts per keeper, plan prices and cleanup time into a cost per usable asset and a monthly bill. Use the calculator on this page with a plan preset or your own price and credits, or follow the method below by hand. The economic reasoning is on cost per usable asset.
What it helps you decide
Which plan or pack covers your volume, what a batch will cost under pessimistic and optimistic retry counts, and how much of the total is credits versus your own time.
Inputs
- Vendor and plan, or a custom credit price.
- Billing basis: monthly price, or annual price divided by 12. Keep these labeled; never mix them.
- Assets needed, N_assets.
- Credits per attempt, G, plus per-attempt add-ons T (texture at generation).
- Attempts per usable asset, A. There is no default; enter your own, and try a low and a high value.
- Once-per-keeper credits, K: remesh, rig, animate, convert.
- Cleanup minutes per asset, M, and your hourly value, H.
- Whether unused credits carry over (a yes/no toggle; see limits).
Calculation
- Credits per usable asset: C = (G + T) x A + K
- Total credits: C x N_assets
- Plan cost, if credits do not carry over month to month: months = ceil(total credits / monthly credits); plan cost = months x monthly price
- Credit price per credit: plan price / plan credits (marginal view)
- Cleanup cost per asset: M x H / 60
- Cost per usable asset: plan cost / N_assets + cleanup cost (allocation view), or C x credit price + cleanup cost (marginal view)
Show both views, since they diverge when you underuse a plan.

| Vendor | Documented credit costs | Price per credit from the same source |
|---|---|---|
| Meshy (web app) | Text to 3D 20 (Meshy 6) or 10 (6 Lite); Image to 3D 20, or 25 on paid plans that start Meshy 7.1 at Ultra 2K; texture add-on 10; AI Texturing 10 (15 at 8K) | Monthly: Pro $20/1,000 = $0.02; Premium $40/3,000 = about $0.0133; Ultra $100/8,000 = $0.0125. Yearly prices not confirmed |
| Meshy (API) | Text preview 20; image to 3D mesh-only 20, textured 30 (2K/4K), 35 (8K); rig 5; remesh 5; animation 3 | Same plans |
| Tripo (API) | Text to 3D 10 to 20; Image to 3D 20 to 30 (the 30 already includes standard texture, so do not add texture to it); detailed or 8K add 10 or 20; P2 100 to 130; texture 10 to 30; retopology 10 to 40; auto rig 25 | 1 credit = $0.01 (API). Plan prices could not be fetched (403); search snippets conflict |
| Hunyuan3D (hosted API) | Textured 25; PBR +10; multi-view +10; smart topology 50 | Prepaid 1,000 credits $15; postpaid $0.02 per credit |
| 3D AI Studio | Image or text to 3D 20 to 60 by model (FAQ; Prism 3.1 35, Tripo P2 70; its pricing page says 20, its homepage 25 to 35) | Basic $19 for 1,000 credits monthly (FAQ); other pages conflict |
| Rodin Gen-2.5 (API) | Base 0.5 credit; Extreme-High +0.5; extreme-high texture +2.0 | Direct credits $1.5 each; API credit value not reconciled with this |
Rodin’s monthly credit allowance per plan is not listed, so a plan-based calculation for Rodin cannot be completed from public data. Web-app and API prices differ for Meshy (remesh and rig are 0 in the web app, 5 in the API); the tool must ask which surface you use.
Worked example you can follow by hand
Meshy, Pro plan, 30 props. Credit costs and prices are dated sources. The attempt counts are assumptions, the same two cases as on the Meshy pricing page, not measured rates.
- Low case. G = 25, T = 0, A = 1 (assumed), K = 0. C = 25. Total = 750 credits. Months on Pro = ceil(750/1,000) = 1; plan cost $20. Allocation view: $20 / 30 = $0.67 per asset. Marginal view: 25 x $0.02 = $0.50.
- High case. G = 25, T = 10, A = 2 (assumed), K = 0. C = 70. Total = 2,100 credits. On Pro with no carry-over: ceil(2,100/1,000) = 3 months, $60, so $2.00 per asset allocation. On Premium: ceil(2,100/3,000) = 1 month, $40, so $1.33. Marginal on Pro: 70 x $0.02 = $1.40.
- Cleanup, as a break-even. We do not supply M. With an assumed H of $30 an hour, one minute of cleanup costs $0.50, so the high-case credit cost of $2.00 equals four minutes of your time, and the low case $0.50 equals one minute. If your cleanup per asset runs longer than that, labor is the larger term, which is why M is the input that usually decides the answer and you must supply it.
Limits
Credit costs and plans change; the tool needs a dated data file and a visible “prices as of” stamp. Meshy’s failed generations are not charged per its docs, but a completed unusable mesh is, so A must count those. Credit rollover is conflicting: Meshy’s Terms (s.2.10, as read by our fetch tool) say additional credits stay available up to one year from purchase and monthly features do not roll over, while the web-app docs say purchased and permanent credits do not expire and are silent on unused monthly credits. Retry allowances such as Meshy’s “retries per task” are not explained, so they are excluded. Tripo, 3D AI Studio and Rodin data are partial for the reasons above.
