Food math: the only math that actually matters. Plan parties, brew perfect coffee, and track your spending with free food & lifestyle calculators. Calculate pizza needs, taco quantities, party drinks, coffee ratios, and lunch savings. We help you plan perfect gatherings (and roast your questionable eating habits along the way).
Use our Pizza Calculator. Enter number of people and slices per person (default: 3). The calculator uses 8 slices per large pizza. For 20 people at 3 slices each, you need 8 large pizzas. Add 1-2 extra for safety (and because leftover pizza is never wasted).
Our Tacos Calculator uses the standard 3 tacos per person. Enter your guest count, and it calculates the total. For 20 people, that's 60 tacos. Consider adding 10-20% extra for hungry guests or people wanting seconds.
Use our Party Drinks Calculator. Enter number of guests and duration (hours). The formula is: Total Drinks = Guests × Hours. For a 100-person party lasting 4 hours, you need 400 drinks. Add 10-20% buffer for unexpected guests.
The standard is 1:16 (1 gram coffee per 16ml water). Our Coffee Ratio Calculator lets you adjust this. For 500ml water at 1:16, you need 31g coffee beans. Use 1:15 for stronger coffee, 1:17 for lighter.
Our Lunch Savings Calculator shows you. Enter lunch cost, times per week, and currency. For $12 lunch, 5 times per week: that's $3,120 per year. The calculator also roasts your spending habits (because sometimes the truth hurts).
Yes. They use standard serving sizes and industry formulas. Pizza (8 slices per large), tacos (3 per person), drinks (1 per person per hour), coffee (1:16 ratio), and lunch costs (weekly × 52). Results are estimates, but they're based on real math, not your "I'll just wing it" strategy.
