Calculators

BBQ, party, VAT, investment yield, and pizza calculators with clear assumptions.

Rough quantities for events, VAT checks, compound yield illustrations, or pizza portions — quick sanity checks, not spreadsheets.

Simple fields for adults, children, and appetite — instant estimates for meat, linguiça-style sausage, charcoal, ice, and soft drinks. Runs only in your browser.

Enter adults, children, hours, and whether you are serving snacks only or a meal — get starter numbers for cake, salgadinhos, and drinks.

Simulate months of compounding with separate monthly or annual rates for return, admin, and inflation — runs entirely in your browser.

Pizza Calculator locally in your tab — quick and privacy-friendly.
