Daily Pace
Daily pace spreads your budget evenly across the period. It is the budget divided by the number of days in it.
Each day adds one more day's pace to what you could have spent so far. The figure on each budget is the difference between that amount and what you have actually spent.
Reading the Figure
Under Pace
Shown in green with a plus sign. You have spent less than the pace so far, and the difference stays available for the rest of the period.
Over Pace
Shown in red with a minus sign. You have spent more than the pace so far. Spending less in the days ahead brings you back on pace.
