📌 Stage 5 · Scenarios and Variance · Plan vs Actual · variance review · 35–45 min
Actuals typed from the close, plan pulled live
Learning goals
- Read the variance layout: actual, plan, variance per month plus a Q1 column
- Retrace the variance identity as a formula
- Interpret the Q1 story: revenue ahead, collections behind
- Decide what action a variance justifies
Concepts
The layout
Plan vs Actual compares seven lines — total revenue, contractor cost, salaries, total operating expenses, net profit, collections, and closing cash — across January, February, and March, then rolls each into a Q1 column. For every month there are three cells: the actual typed from the bookkeeping close (white), the plan pulled live from the driver sheets (pale-green), and the variance.
Only the actual columns (C, F, I) are typed. The plan columns link straight to the model: D5 = 'Monthly P&L'!C8, J11 = 'Cash Roll-Forward'!E8, and so on — so the comparison can never drift out of sync with the plan.
The variance identity
Every variance cell is the same subtraction, and every Q1 column is either a sum of the three months (for flows like revenue and profit) or a repeat of March (for the closing-cash balance, which is a point in time). That is why the Q1 revenue variance of $1,200.00 equals the sum of the monthly variances: $1,525.00 − $2,050.00 + $1,725.00.
=C5-D5Plan vs Actual E5 (January revenue variance): actual $50,400.00 − plan $48,875.00 = $1,525.00 favorable. A positive variance means ahead of plan; a negative one means behind. Q1 sums the three months for flows, and repeats March for the closing-cash balance, because a balance is a snapshot.
The Q1 story
Three Q1 variances tell the whole quarter:
Revenue +$1,200.00 ahead of plan ($162,200.00 actual vs $161,000.00 plan).
Collections −$1,000.00 behind ($163,037.50 vs $164,037.50) — the studio billed ahead of plan but banked less than the plan assumed.
Net profit +$995.00 ahead ($9,277.00 vs $8,282.00), with closing cash −$1,039.59 behind ($40,925.00 vs $41,964.59).
Revenue ahead, cash behind is the classic signature of slower payment: the earnings are real, but the bank balance is late. The response is not panic about the P&L — it is tightening NET 30 follow-up, because Lesson 7 showed receivables are already the plan's slowest-moving asset.
What a variance justifies
A variance is not an instruction; it is evidence. The discipline: explain every line above a threshold you set in advance (say $1,000.00 or 5%), then change a driver only when the explanation points to a durable cause. One slow month is noise; three months of collections behind plan is a reason to retest the collection curve on Assumptions — a change that ripples through the cash plan honestly, instead of quietly overwriting the formula.
Practice
Fixed case: Harbor Creative Studio LLC, a four-person design studio in Austin, Texas, planning calendar year 2026. Cached numbers are the Base scenario. Pale-green cells are formulas; white cells are typed inputs. The exercise opens on the sheet this lesson teaches. Cell E5 (January revenue variance) is blank: retype the variance formula.
- Open Plan vs Actual — The exercise opens on Plan vs Actual. Columns C-E are January, F-H February, I-K March, and L-N the Q1 roll-up. Actual columns are typed; plan and Q1 columns are formulas.
- Retype the variance formula in E5 — Cell E5 is empty. Type =C5-D5 and confirm: it should return $1,525.00 (actual $50,400.00 vs plan $48,875.00).
- Scan the monthly variances — H5 (February revenue variance) reads −$2,050.00 and K5 (March) $1,725.00 — revenue is choppy month to month, which is normal for a project business; the Q1 column is what smooths it out.
- Read the Q1 story — N5 (Q1 revenue variance) reads $1,200.00, N9 (Q1 net profit variance) $995.00, N10 (Q1 collections variance) −$1,000.00, and N11 (closing cash variance) −$1,039.59.
- Write the one-line explanation — In your own words: billings ran ahead of plan, but collections lagged, so profit is ahead and cash is behind. That sentence is what a monthly close is for.

Checklist
Work through each item; when every box passes, this lesson is done:
- ☐ Retyped =C5-D5 in E5 and it returned $1,525.00
- ☐ Q1 variances read: revenue $1,200.00, net profit $995.00, collections −$1,000.00, closing cash −$1,039.59
- ☐ Can explain why revenue ahead and collections behind points at payment timing, not demand
- ☐ Can state the threshold rule for when a variance earns a driver change
