Frequently Asked Questions

What are examples of Fixed Costs vs Variable Costs? ▼

Fixed costs remain constant regardless of production (rent, full time payroll, insurance). Variable costs increase directly with each unit sold (raw materials, packaging, packaging fees).

How can I lower my break even threshold? ▼

You can lower your break even point by raising selling prices, reducing variable production costs, or renegotiating fixed overhead commitments.

What is Contribution Margin? ▼

Contribution margin is the remaining revenue from each unit sold after covering its variable cost that contributes toward paying fixed monthly overhead.
