The Operator's Read
A line of credit is flexible, cheap money for short-term needs — but only if you pay it down. Carrying a revolving balance long-term turns a cash-flow tool into an expensive habit. Educational only.
Assumptions & Limitations
- •The model is deterministic: it projects your inputs forward with clear arithmetic, not a Monte-Carlo or probabilistic forecast. It shows one scenario at a time — run several to bracket a range.
- •Defaults are illustrative benchmarks, not your business. Replace every field with your real numbers before drawing conclusions.
- •It abstracts away taxes, financing, seasonality, and one-off events unless a field explicitly captures them. Treat the output as a directional estimate.
- •This is an educational tool, not financial, investment, tax, or legal advice. Validate real decisions with a qualified professional.
