# Weekly calorie calculator

Enter your weekly budget and the days so far. The calculator shows how much you have left for each open day.

**In short:** **Formula:** calories left = weekly budget minus calories eaten so far. Divide by the number of open days to get your daily allowance. Example: 14,000 minus 5,700 (Monday to Wednesday) leaves 8,300 calories for 4 days, or about 2,075 per day.

## How to use it

1. Enter your weekly budget. Don't know it? Use the [calorie deficit calculator](https://weekfuel.app/en/calorie-deficit-calculator/).
2. Enter the calories for each day that's already over.
3. Leave future days empty. The calculator spreads the rest evenly across them.

## Example

Sam has a weekly budget of 14,000 calories. Monday 1,850, Tuesday 2,100, Wednesday 1,750, so 5,700 in total. Thursday to Sunday leaves 8,300 calories, just over 2,000 a day. Dinner out on Saturday? Plan Thursday and Friday a little lighter.

## Frequently asked questions

### What if I'm already over my weekly budget?

Then the week is maintenance instead of a deficit. Don't punish yourself with very little food – just start the next week as normal.

### Do I have to split the rest evenly?

No. Even is just the suggestion. If Saturday's going to be bigger, shift some calories there.
