AI Token Cost Calculator

How to Use the AI Token Cost Calculator

The AI Token Cost Calculator turns your daily model queries into concrete dollar amounts. All you need to provide is five values:

• Queries per day – how many times per day you send a request to the model. Default: 1000.
• Input tokens per request – how many tokens you send on average in one request, including the prompt, instruction, and context. Default: 800.
• Output tokens per request – how many tokens the model returns on average in a response. Default: 400.
• Input price – the rate per million tokens sent to the model. Default: $0.15.
• Output price – the rate per million tokens generated by the model. Default: $0.6.

You get the result right away in three amounts: daily cost, monthly cost, and annual cost. By default, the calculator uses US dollars, but you can enter your own rates to calculate in any currency.

Example with the default values: 1000 queries × 800 input tokens gives 800,000 input tokens per day, or 0.8 million × $0.15 = $0.12. The output is 1000 × 400 = 400,000 tokens, or 0.4 million × $0.6 = $0.24. The total daily cost is $0.36, the monthly cost is $10.8, and the annual cost is $131.4.

How to Set Input and Output Prices for a Model

The prices you enter in the calculator are rates per million tokens. They are not fixed. The default values of $0.15 and $0.6 are only a starting point that you can change at any time.

To set your own rates, check the current pricing page for the model provider you use. Pay attention to a few things:

• whether the pricing separates input and output tokens – output is usually more expensive,
• which model the rate applies to, because prices vary by model,
• whether the amount is given per million tokens or in another unit – if not, convert it to per million,
• whether the rate applies to standard processing or another option, such as batch processing.

If you use several models, calculate each one separately and add the results. That makes it easier to see which part of your project creates the largest cost and where it may be worth making changes.

Keep in mind that prices change, so before you plan a serious budget, always check the current rates from your provider and enter them into the calculator again.

How to Estimate a Monthly and Annual AI Budget

The calculator multiplies the daily cost by 30 days to show the monthly cost and by 365 days to show the annual cost. That lets you see a longer time horizon at a glance instead of calculating everything by hand.

When planning a budget, it is worth paying attention to a few details:

1. Set a realistic number of queries per day. It is better to base it on data from recent weeks than on an assumption that traffic will be low.
2. Account for peak days. If you get more queries around holidays or during a campaign, also calculate a version with a higher number.
3. Add a buffer for project growth. Even a 20% to 30% reserve helps you avoid budget surprises.
4. Save the result and compare it with your actual bill every month so you can catch changes early.

The assumptions in the calculator are simple: 30 days per month and 365 days per year. Your actual month may have a different number of days, so treat the result as a solid planning baseline, not an exact bill.

How to Lower Token Costs with Caching, Batch, and Shorter Prompts

The calculator uses the rates you enter, so it shows the cost without automatic discounts. You can lower it by changing how you work with the model.

• Caching (prompt cache): if you send the same long instruction in every request, many providers let you pay less for the repeated part. In the calculator, enter the lower effective input rate.
• Batch processing: tasks that do not need to be ready immediately can be sent in batches. This can be cheaper, although you wait longer for a response.
• Shorter prompts: remove repetition and unnecessary context. Every sentence less means fewer input tokens on every request.
• Shorter responses: limit response length when a full breakdown is not needed. Output tokens are usually more expensive, so the savings can be noticeable.
• Model selection: route simple tasks to a smaller, cheaper model and leave difficult ones to the larger model.

Check what discount terms your provider offers and how much the rates actually drop, then enter those values into the calculator and compare the results before and after the changes.

Calculator Limits – What It Does Not Calculate

The calculator is a tool for quick estimates. It counts only what follows from the queries, tokens, and rates you enter. It intentionally does not include:

• fixed fees and subscriptions,
• taxes and other charges,
• current exchange rates or live provider pricing,
• discounts for caching and batch processing,
• free limits, startup credits, and minimum billing thresholds,
• individual contract terms and negotiated rates.

It also does not account for differences in month length. It assumes 30 days per month and 365 days per year. That is why the result is an estimate: it works well for comparing models and planning a budget, but always confirm the final amount on your model provider's bill.
