Calculators for your weekly calories
All calculators run entirely in your browser. Nothing is sent, nothing is stored.
In short
Use these four calculators to plan your week: start with your BMR and TDEE, choose a sensible deficit, use the weekly calorie calculator to spread what's left, and plan parties with the weekend calculator.
Most calorie calculators online think in days. Ours always show the weekly numbers too, because that's how Weekfuel works: you have a weekly budget, and individual days can be bigger or smaller. Every formula is spelled out on its page so you can check each result yourself.
All calculators
Calorie deficit calculator

Weekly calorie calculator
What you've eaten so far and how much is left per open day.
