How much can I spend per day?

Enter your budget and the period. The calculator shows your daily amount and, if you have already spent something, how much you can spend per day from today on. Everything stays in your browser, nothing is stored.

For example your money for groceries, free time or a vacation. Don't know your budget? Open the budget calculator

Optional. Spending before today that already comes out of the budget.

How it is calculated

Your daily budget is the money you have left, spread evenly across the remaining days of the period:

Daily amount = (budget − spending so far) ÷ days left

If you spend no more than this amount each day, your budget lasts exactly until the end. Spend more on one day and the amount for the following days gets a little smaller. Spend less and it grows again.

Example: €600 for 30 days gives €20 per day. If you have spent €260 after 10 days, €340 remain for 20 days, which is €17 per day.

All of this, every day, without the math.
