Outcome
Where your budget will land
An overrun found at month end is too late to steer. Project where a budget will land from what has been spent so far.
What it comes to
Fill in every field to see the result.
- Forecast at the current pace
- 135 000 €
- Against budget
- +15 000 €
- Against budget (%)
- +12.5%
More than 10 % over plan: in Flowtly, this budget would raise an alert.
How the figure is calculated
- In words
- Divide what has been spent by the share of the period that has gone to get a straight-line forecast, then compare it with the budget.
- In symbols
- Forecast at the current pace = S ÷ T
- Against budget = S ÷ T − B
- Against budget (%) = (S ÷ T − B) ÷ B
- With your numbers
Fill in every field to see the result.
- 54 000 € ÷ 40% = 135 000 €
- 135 000 € − 120 000 € = 15 000 €
Assumptions
- A straight line is the simplest trend: it assumes the rest of the period runs at the pace so far. Front-loaded or seasonal spending needs a monthly plan instead.
- A negative figure against budget means the forecast lands under it.
How Flowtly measures this
- 1A budget can start by observing actuals; add a monthly plan with percentage, fixed or per-unit growth once you know the pattern.Read the guide
- 2Budgets per project, client or team track real spend against plan, so an overrun shows early.Read the guide
- 3Every morning Flowtly checks each planned budget and notifies its recipients when costs run more than 10 % over plan or the margin falls below target. It never changes the budget for you.Read the guide
