How we build & maintain these calculators

Our marketing, HR and utility tools use standard formulas — funnel and ROAS math, employment-notice and overtime calculations, and exact unit-conversion factors — plus published reference data where relevant. Because platform fees, labour rules and standards change, the tools state their assumptions and are meant as quick planning aids rather than authoritative sources.

Guides & deep dives behind the numbers

The calculators give you a figure; these write-ups explain the reasoning and how to act on the result.

Frequently asked questions

What is a good ROAS?

Return on ad spend depends on your margin and goals; a common first target is 4:1, but break-even ROAS is set by your product margin. The calculator shows your break-even point.

Are the unit converters accurate?

Yes — they use exact, published conversion factors (length, power, pressure). Rounding is only applied for display.

Can I rely on the HR calculators for legal compliance?

No. Notice, overtime and coverage rules vary by jurisdiction and change. Use them for planning and confirm obligations against local employment law.
