What it does
Financial Calculator is an agent skill from dkyazzentwatwa/chatgpt-skills. Run loan, investment, NPV, retirement, savings, and risk calculations with schedules and charts. Use for deterministic financial modeling tasks.
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `agents/openai.yaml` and `scripts/financial_calc.py`).
It sits in Business, Finance & HR, covering Financial modeling. The repository describes itself as: My comprehensive, tested + audited, library of skills to use for ChatGPT.
When your agent uses it
- Deterministic financial modeling tasks
- Tasks that involve Financial modeling
Example prompts
- “/financial-calculator”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Confirm units and assumptions first: rates, compounding, time horizon, taxes, and inflation.
- Use scripts/financial_calc.py as the source of truth for the computation.
- Return both the answer and the assumptions that materially drive it.
What it can do on your machine
Read from SKILL.md and the folder at commit 103b430. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Financial Calculator loads about 234 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 97 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 97 words (~234 tokens).
“Use deterministic calculations instead of ad hoc spreadsheet math when the user needs precise financial outputs.”
