Getting Started

You are 7 months into the fiscal year. Your job is to project year-end expenditures and revenues using three different forecasting formulas, select the best estimate for each line item, and compare projections to the adopted budget.

Three Forecasting Approaches

  • Average Spending: Assumes uniform spending each month
  • Seasonal Spending: Uses last year's spending pattern as a template
  • Current Month: Projects based on the most recent month's spending

Data Structure

Both the Exp and Rev tabs have columns: MTD (month-to-date), YTD (year-to-date, 7 months), Last Year YTD, Last Year Total, and Adopted Budget.

Average Spending Formula

This assumes spending is approximately the same from month to month — common for routine functions like base salaries.

Average Spending Formula
Projected Year-End = (YTD ÷ 7) × 5 + YTD
=(D5/7*5)+D5
7 months elapsed, 5 remaining. This equals YTD × 12/7.

Worked Example — Salaries

($2,519,700÷ 7 × 5) +$2,519,700=loading...

What to Do

1In column H, label "AVERAGE FORMULA". In H5 type =(D5/7*5)+D5
2Copy down to H36 for all expenditure line items. Sum the column.

Concept: YTD represents 7 months of spending. Dividing by 7 gives the monthly average. Multiplying by 5 projects the remaining months. Adding YTD gives the full-year projection.
Detail: This simplifies to YTD × 12/7. For Salaries: 2,519,700 × 12/7 = 4,319,485.71

Seasonal & Current Month Formulas

The Seasonal Formula assumes spending follows the same seasonal pattern as last year. The Current Month Formula extrapolates from the most recent month.

Seasonal Formula
=IF(OR(LastTotal=0, LastYTD=0), 0, YTD ÷ (LastYTD ÷ LastTotal))
=IF(OR(F5=0,E5=0),0,D5/(E5/F5))
The ratio LastYTD/LastTotal represents what fraction of the year's spending had occurred by this point last year.
Current Month Formula
= (MTD × 5) + YTD
=(C5*5)+D5
Assumes the remaining 5 months will each look like the most recent month.

Worked Examples — Salaries

Seasonal:$2,519,700÷ ($2,125,300÷$4,268,300) =loading...
Current Month:($360,000× 5) +$2,519,700=loading...
Need Help?
Concept: The seasonal formula asks: "By this point last year, what % of the year's spending had occurred?" If 50% had been spent by month 7 last year, and this year's YTD is $100k, then the projection is $200k.
Detail: Watch for zero values! Building Construction has $0 YTD and $0 last year YTD. The IF statement handles this by returning 0.

Select Best Estimate

Assign formula 1 to the first line item, formula 2 to the second, formula 3 to the third, repeating the pattern (1, 2, 3) for all line items. Then compute the End of Year Estimate using the selected formula.

End of Year Estimate
=IF(L=1, AvgFormula, IF(L=2, SeasonalFormula, CurrentMonthFormula)) + ManualAdj
=(IF(L5=1,H5,IF(L5=2,I5,J5)))+K5
Need Help?
Concept: The IF statement checks column L. If L5=1, it grabs the Average formula (H5). If L5=2, it grabs Seasonal (I5). Otherwise, Current Month (J5). Column K adds any manual adjustment.
Detail: Column L pattern: 1,2,3,1,2,3... So row 5=1(Avg), row 6=2(Seasonal), row 7=3(Current), row 8=1(Avg), etc.

Variance & Budget Comparison

Compute the variance (Adopted Budget − EOY Estimate) for each line item. Negative values mean the line item is projected to exceed the adopted budget. Then compare total revenues to total expenditures.

Variance
Variance = Adopted Budget − End of Year Estimate
=G5-M5

Three Projection Methods Compared

Comparison of Average, Seasonal, and Current Month projections against the adopted budget.
Need Help?
Concept: A positive variance means spending is under budget. A negative variance (shown in brackets) means spending is over budget.
Detail: Repeat all formulas for the Revenue tab. Then compare total EOY Revenue vs EOY Expenditure.
