Hello! I'm Yagi from the East Japan Sales Division.
Among the many consultations I receive from non-engineers about utilizing Claude, one of the most frequent questions is "How much does it actually cost?"
Since it depends on the amount of prompt input and the model used,
I couldn't give a clear answer like "It costs X yen!", which I found frustrating.
So today, I'm going to verify how much it costs to run the Skills I use on a daily basis.
Prerequisites
The usage fees will be compared by checking the current usage before and after running Skills, which can be found under Settings > Usage.
As for the model, I'm running it with Sonnet 4.6 at Low effort setting.

Creating Handover Documents (Connector to Document)
I'll request the creation of a customer handover document.
For the handover document creation Skills, I'm using the ones introduced in the following blog post!
In brief, the Skills work as follows:
- Information sources: HubSpot deal and contact information, Google Drive meeting minutes and company information files, team weekly reports in Google Docs, company official website and IR information
- After verifying consistency and consolidating the collected information, it automatically generates an 11-chapter Word file (.docx)
- Upon completion, it automatically uploads to the customer folder in Google Drive
Before

After

As output, it created an 11-page document.
This task cost $3.34 to execute.
Since it reads many files and creates documents, it's a relatively heavy process.
If you use these Skills every day, that would be approximately $3.34 × 20 business days × 160 yen = about 10,688 yen per month.
Creating Weekly Reports (Connector to Text)
Let me request the creation of a weekly activity report in text format.
I've created Skills for generating weekly sales activity reports as text, so I'll run those.
Before

After

The output was approximately 2,500 characters. This task cost $1.23.
While accessing multiple resources to gather information is similar to the handover document,
since the output is text, the task can be executed at a lower cost compared to before.
If you use these Skills every week, that would be approximately $1.23 × 4 weeks × 160 yen = about 787 yen per month.
Blog Review (Text to Text)
Next, I'd like to ask for a review of this blog post.
Since this isn't something I've turned into Skills, I'll run it by entering the prompt directly.
Before

After

This task consumed $0.14.
As expected, working with text only allows for much more affordable usage!
As output, it produced 3 recommendations for additional content from a readability perspective, and 2 points for typo and grammatical error checks.
If you make this type of request 5 times every day, that would be approximately $0.7 × 20 business days × 160 yen = about 2,240 yen per month.
Summary
This time, I verified how much it costs to use Claude in the ways I actually utilize it on a daily basis.
Combining the monthly estimates for each task, the total comes to approximately 13,715 yen ($85.72).
Since plans like Enterprise use pay-as-you-go pricing, I'd also like to learn token-saving techniques to avoid any wasteful spending.
