Instead of building yet another spreadsheet or eyeballing compound interest in your head, this skill runs the actual formulas for loans, NPV, retirement drawdowns, and investment projections. It wraps a Python script that handles the math deterministically, which matters when you're modeling scenarios where rounding and compounding order actually affect the answer. The workflow is sensible: nail down your assumptions (rates, time horizon, compounding frequency), run the calculation, and get back both the number and the assumptions that drove it. Good for when you need to show your work or compare scenarios side by side, not for personalized financial advice.
