OpenAI Price Calculator
Free browser calculator that estimates OpenAI API costs across 50+ models, from GPT-5.6 Sol to GPT-4o mini.
Worth bookmarking if you are quoting or budgeting OpenAI spend and want GPT-5.6 Sol/Terra/Luna rates without digging through a pricing PDF. It covers a wider model list than most free calculators, and it is one of the few that splits real-time text and audio rates — gpt-realtime-2 audio runs $32/$64 per 1M tokens against $4/$24 for text, a gap that quietly wrecks voice-app budgets. But it is arithmetic on published list prices, not accounting: no account connection, no usage history, no enterprise or volume discounts. Use it to size a build, then reconcile against OpenAI's own billing. For Claude or Gemini numbers, put the site's own Multi-AI scripts or another provider calculator next to

Skip it if you need actual spend reconciled against your OpenAI invoice or committed-use discount rates modelled, rather than a list-price projection from token estimates you typed in yourself.
The calculator itself is free, so the real cost decision is what the paid companion products cost: the Multi-AI Google Sheets Script 4.0 lists at $39 and the Multi-AI Airtable Script 4.0 at $59, both shown discounted to $19 and $29 respectively. Those are one-off purchases routing 300+ models through OpenRouter, which is cheaper than most multi-provider cost platforms but only worth it if you need Claude and Gemini alongside OpenAI.

What is OpenAI Price Calculator?
OpenAI Price Calculator — Free browser calculator that estimates OpenAI API costs across 50+ models, from GPT-5.6 Sol to GPT-4o mini. Best for Developers scoping a new OpenAI-powered feature, Content teams budgeting bulk text generation, Agencies quoting AI project costs to clients. Free to use.
The OpenAI API Pricing Calculator by InvertedStone is a free, browser-based tool for working out what a given OpenAI workload should cost before you commit budget to it. You pick a model, enter estimated input and output token counts — or drag the sliders — and it returns input cost, output cost and a total using the published per-million-token list rates. A word-to-token reference is built in (the page shows roughly 750 words per 1,000 tokens), and a checkbox applies cached-input pricing where a model offers it. Model coverage is unusually wide: the GPT-5.6 family (Sol at $5/$30 per 1M tokens, Terra at $2.50/$15, Luna at $1/$6), GPT-5.5 and GPT-5.5-pro ($30/$180), GPT-5.4 pro and GPT-5.4 plus mini and nano, GPT-5.3 Codex, GPT-5.2 pro and GPT-5.2 Codex, GPT-5.1 and its Codex variants, GPT-5 pro and GPT-5, o3-pro ($20/$80), o3 Deep Research and o4-mini Deep Research, the real-time models with separate text and audio rates (gpt-realtime-2, gpt-realtime-1.5, gpt-realtime-mini), GPT-4.1, GPT-4o and the GPT-4o Search Preview pair, and legacy O1 and O3-mini. Developers sizing a chatbot, content teams budgeting a generation pipeline, and agencies quoting AI work to clients are the core audience. It is a planning aid, not a billing dashboard: it never connects to your OpenAI account, so it shows what a projected token volume should cost at list rates, not what you actually spent.

Limitations
- Free static web calculator.
- You enter estimated input and output token counts; it never connects to your OpenAI account, so it cannot report what you actually spent.
- Rates are manually maintained from published list prices and can lag behind OpenAI price changes, and they do not model enterprise agreements or volume discounts.
- Caching is only partially supported — the toggle applies a cached input rate where a model has one, but it does not model cache write costs or hit ratios.
- Coverage is OpenAI models only; there are no Claude, Gemini or Cohere comparisons in this calculator.

Where the pricing makes sense
The company stage and team size where OpenAI Price Calculator's pricing actually pencils out — and where peers do it cheaper.

Who should pick OpenAI Price Calculator?
Pick OpenAI Price Calculator if you are Developers scoping a new OpenAI-powered feature, Content teams budgeting bulk text generation, Agencies quoting AI project costs to clients, Product managers comparing model economics.
Look elsewhere if you are Teams that need Claude or Gemini cost estimates in the same tool, Anyone wanting actual OpenAI account usage or billing data, Buyers needing enterprise or volume-discount pricing modelled, Users who want to run API calls from the calculator itself.
Skip it if you need actual spend reconciled against your OpenAI invoice or committed-use discount rates modelled, rather than a list-price projection from token estimates you typed in yourself.
GeneratedReal-world workflow fit
Concrete scenarios for the personas OpenAI Price Calculator actually fits — and what changes day-one when you adopt it.
You estimate 2M input and 4M output tokens a month, then run the same numbers against GPT-5.6 Sol, Terra and Luna to see where the cost curve sits.
Outcome: You pick a model tier with a defensible monthly number to take into a build-vs-buy conversation, then reconcile it against OpenAI's billing after launch.
You price a mixed workload — Codex generation at $1.75/$14 plus o3-pro reasoning calls at $20/$80 — so the expensive reasoning line is visible in the quote rather than averaged away.
Outcome: The client sees why the reasoning portion dominates the budget, and you avoid eating an overage when the reasoning call volume grows.
You convert your monthly word volume into tokens using the built-in 750-words-per-1,000-tokens reference, then check whether cached input pricing changes the total.
Outcome: You get a first-pass content budget without needing anyone on the team to understand tokenisation.
Use cases
- Estimate the monthly API cost of a GPT-5.6 Sol chatbot before you start building it.
- Compare GPT-5.6 Luna ($1/$6), GPT-5.4 mini ($0.75/$4.50) and o4-mini ($1.10/$4.40) for a high-volume text pipeline.
- Budget the audio-side spend for a voice app on gpt-realtime-2 ($32/$64) versus gpt-realtime-mini ($10/$20).
- Model whether input caching makes a repetitive-prompt workload cheaper on GPT-5.5.
- Quote a client project that mixes Codex generation at $1.75/$14 with o3-pro reasoning calls at $20/$80.
- Decide between o3 Deep Research ($10/$40) and o4-mini Deep Research ($2/$8) for a research feature.
Setup time & first value
How long it actually takes to get something useful out of OpenAI Price Calculator — broken out by persona, not the marketing-page minute.
Zero setup: open the page, pick the model, and type or slide your token numbers — first estimate in under two minutes. The word-to-token reference removes the only real friction, which is not knowing what a document costs in tokens. If you want the paid multi-provider sheets, budget a short install on top.
Switching to or from OpenAI Price Calculator
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual pricing PDFs: use the calculator's model table instead of cross-referencing OpenAI's published rate sheet by hand.
- →From a generic token counter: take your token estimates across and get per-model dollar totals rather than raw counts.
- →From a spreadsheet you maintain yourself: the calculator already holds roughly 45 model rows including real-time text and audio splits.
- ↗To OpenAI's own usage dashboard: reconcile projected list-price estimates against what your account actually billed.
- ↗To Multi-AI Google Sheets Script 4.0: when you need OpenAI, Claude and Gemini costs side by side in one sheet.
- ↗To Multi-AI Airtable Script 4.0: when the cost model needs to live next to project records in Airtable.
