Business decision hub
Use these calculators together when sizing spend, debt, or growth—not as tax or legal advice. See the startup metrics benchmark for industry planning bands (CAC, LTV, churn, burn). CAC (customer acquisition cost) is spend divided by new customers; LTV is revenue per customer over retention; break-even is when cumulative gain covers fixed cost. Burn is cash spent per month before profitability; margin is revenue minus direct costs—track both before scaling ads or headcount.
Suggested workflow
- Size the opportunity with ROI or percentage tools.
- Check financing cost with loan or EMI calculators.
- Model cash runway with compound interest and salary/tax tools.
Common mistakes
- Using marketing ROI outputs as audited financial statements—treat them as directional scenarios.
- Comparing CAC or LTV across tools without matching time windows (monthly spend vs annual revenue).
- Ignoring financing cost when a campaign looks profitable on gross margin alone.
- Applying US tax or salary estimates to non-US offers without checking local rules.

FAQ
What ROI formula is used?
ROI % = (gain − cost) ÷ cost × 100. Productivity mode values hours saved × hourly rate as gain.
Is this financial advice?
No. It is a simplified educational calculator—not accounting, tax, or investment advice.
Can ROI be negative?
Yes. If gain is less than cost, net profit and ROI reflect the loss.
What is return multiple?
Gain divided by cost (e.g. 2.5× means gain is 2.5 times the cost).
