Pricing & ROI Learning
Core concepts behind the calculator toolkit.
Why rates beat guesswork
Underpricing freelancers often ignore taxes, non-billable time, and expenses. A clear hourly floor protects cash flow.
LTV vs CAC
Healthy growth usually needs LTV meaningfully above CAC. Pair both calculators before scaling paid acquisition.
Marketplace fee drag
Amazon, Etsy, and eBay fees compound with shipping and ads. Model net profit per unit before listing volume.
AI API budgeting
Token prices look small per request but scale with daily volume. Estimate monthly and yearly spend before launch.
