Why Business Calculators Matter
Business math is simple until you're sitting in a meeting trying to calculate margin, markup, and break-even under pressure. ConvertMart's business calculators handle the standard SMB and startup metrics — profit margin, markup, break-even units, CAC/LTV, burn rate, runway, ROI — and show the formulas so you can defend the numbers when your CFO questions them. Every calculator handles edge cases cleanly: zero revenue, negative margins, subscription vs. one-time pricing, seasonal variance.
Top Use Cases
- Calculate profit margin, markup, and the selling price needed to hit a target margin
- Run break-even analysis to find the unit volume where fixed costs are covered
- Model SaaS unit economics: CAC payback period, LTV:CAC ratio, churn impact on MRR
- Project startup runway from current cash and monthly burn rate
- Calculate cash flow under different collection scenarios (net-30 vs net-60)
- Compare ROI across marketing channels (Facebook Ads, Google Ads, email, affiliate) on the same cost basis
How to Use ConvertMart's Business Calculators
Enter your costs and revenues. Most business calculators require just 3-5 inputs (fixed costs, variable cost per unit, selling price, etc.). Results include the headline metric (margin, break-even, ROI) plus a sensitivity analysis showing how the result changes when each input moves ±10%.

Frequently Asked Questions
- Is profit margin the same as markup?
- No. Margin is profit ÷ selling price (%). Markup is profit ÷ cost (%). Example: a $50 product that costs $30 has $20 profit. Margin = 20/50 = 40%. Markup = 20/30 = 66.7%. Retail businesses typically think in terms of margin; manufacturing uses markup. Confusing them is the #1 pricing error in small businesses.
- What LTV:CAC ratio is healthy for SaaS?
- The standard benchmark is 3:1 or better. A 1:1 ratio means you barely break even and every new customer is a loss after accounting for your own time. 5:1+ is excellent and indicates room to increase acquisition spend aggressively. Under 3:1, focus on retention (churn reduction) before scaling acquisition.
