Figures are computed on your device; nothing is sent anywhere.

flexibleAmount = monthlyBudget − fixedCosts; dailyLimit = flexibleAmount ÷ daysInMonth

The flexible amount is what remains of the budget after the fixed costs are set aside, and the daily limit divides that across the days in the month.

Fixed costs come first because rent and bills cannot be skipped, so only what is left is genuinely free to spend day by day.

The limit is a guard rail rather than a target, and carrying any overspend into the next day keeps the month from drifting.

Leaving out a quarterly or annual bill understates the fixed costs and makes the daily limit look larger than it is.
Spending to the limit every single day leaves nothing for the unexpected, so a small buffer inside the daily figure is wise.

Use it at the start of a month to set a spending pace you can actually keep, once the bills are already accounted for.
It is not a savings plan; it only spreads the flexible part of the budget evenly across the days.

A 30000 budget with 12000 of fixed costs over 30 days allows 600 a day.

Flexible amount 18,000.00

Daily limit 600.00

What counts as a fixed cost?

Rent, utilities, loan payments and other bills you cannot skip should all go in before the daily figure means anything.

What if I go over one day?

Carry the shortfall forward, so spending less the next day keeps the month on track.
