FAQs
1) What costs should I include for accuracy?
Include daily items (venue, trainers, equipment), per‑participant items (catering, materials), and flat items (marketing, travel). Add overhead and contingency so surprises don’t break the plan.
2) How does hourly duration affect pricing?
Hourly duration converts to effective days using your hours‑per‑day value. Daily‑rate items multiply by those effective days, while one‑time per‑participant items stay the same.
3) What is the difference between overhead and contingency?
Overhead represents operational burden like admin time and coordination. Contingency is a buffer for uncertainty, such as last‑minute changes, extra supplies, or rate fluctuations.
4) Should I add a target profit for internal workshops?
If you bill another team or client, profit helps protect margins. For internal events, you can set profit to zero and rely on contingency for safety.
5) How should discounts or sponsorships be modeled?
Use a fixed amount when funding is known. Use a percentage when coverage scales with the workshop size. The calculator applies the reduction before tax.
6) Can this estimate break‑even participants?
Yes. Enter a planned price per participant. The tool estimates total revenue, net surplus, ROI, and the participant count needed to cover the total budget.
7) Why do shares exclude the discount line?
Discount reduces the subtotal and can distort category proportions. Shares focus on where money is spent, while the discount is shown separately as a reduction.
8) What should I do if actuals differ from estimates?
Update inputs with real amounts and recalculate. Compare direct costs, overhead, and buffers to see where variance occurred, then adjust pricing or scope for future sessions.
