The winter cash plan: how much to bank before the season ends

Every October the same quiet dread shows up: the phone slows down, the last cleanups get invoiced, and somewhere in the back of your head is the question — do I have enough to get to April? Most operators answer it by feel. Feel is how you end up financing February on a credit card at 20-something percent. The actual number takes ten minutes to compute. Here it is.

Fixed costs don’t take the winter off

Revenue stops; these don’t: shop rent, truck payments, insurance, phone and software, storage, the office help you want back in March. List them honestly — this is your monthly fixed overhead. In the books I see, a typical 6-crew operation runs $6,000–$8,000 a month. We’ll use $7,200.

Don’t guess. Pull last December’s and January’s bank statements and add up what left the account with no crew on a lawn. The statements don’t flatter.

You are also a fixed cost

The line most winter plans skip: your own pay. If the plan only works when you don’t eat from December to February, it isn’t a plan. Put a real number on your monthly draw — say $6,000 — and treat it exactly like rent.

Notice that line is $18,000 of the reserve — nearly half the target. That’s why the winter number always lands bigger than the gut guess. The gut only prices the shop; it forgets the house.

The reserve math

Adjust the pieces to your reality: two dead months instead of three, a plow route that covers half the overhead, a spouse’s income that carries the house. The formula doesn’t change — (fixed overhead + owner pay) × zero-revenue months + a cushion.

The cash calendar: October to April

A target number is abstract. A calendar is not. The target tells you how much; the calendar tells you exactly when it hurts. Here’s the same worked example laid out month by month, assuming the skim ran May through October and five deposits — $36,330 — are already banked by September 30. Overhead plus draw is $13,200 a month all winter.

Every row foots: prior balance, plus deposits, minus draws. Numbers are the worked example — illustrative, not a forecast.

Look at February. The balance at the trough is $4,000 — the cushion, and only the cushion. One blown transmission or one HOA paying 60 days late and you’re negative. That’s with the plan working. Most operators find the trough by standing in it.

And watch March. The crews are back out, but the first invoices don’t turn into deposits until the end of the month — March spends most of its days feeling like February. Being busy and being paid are two different dates on this calendar.

Where the reserve comes from

Divide the reserve by the number of strong collection months you have left and skim it off the top. $43,600 with six good months left is $7,270 a month — about 15% of collections for an operation billing $45–50k a month. Move it the day the money lands, into a separate account you don’t look at, the same way payroll taxes leave before you can spend them.

Now push it down to the crew hour, because that’s where it’s earned. At 600 billable crew hours a month, $7,270 is about $12 of every billable hour that has to survive all the way to the bank. Run the numbers from what a mowing crew hour actually costs: at a $60 rate against a $48.35 fully loaded cost, you keep $11.65 an hour — $6,990 a month on those 600 hours. The mowing margin alone nearly funds the whole skim. Winter lives inside your net margin.

Bill $50 instead and you keep $1.65 an hour — $990 a month. At that pace the skim funds one winter every 44 months. If 15% of collections isn’t there to move, you don’t have a savings problem — you have a pricing problem, and no amount of discipline in October fixes rates that were wrong in May. The fix is upstream: run the kill, keep, or reprice call on every route that can’t carry its $12.

The plow variant: when winter isn’t zero

Plow revenue shrinks the target — but only revenue you can bank on. A seasonal contract that bills $6,000 a month whether it snows or not gets full credit. Per-push work gets half credit at best, because a brown winter pays nothing and your rent doesn’t care about the forecast. Same worked example, illustrative:

If the snow shows up, the surplus rebuilds the cushion early. If it doesn’t, you planned for the winter you got instead of the one you hoped for.

Five ways this plan dies in the books

• Counting receivables as cash. The $9,000 HOA invoice from October is not October money. If it pays in January, it’s January money. Plan on collected dollars only.
• Skipping your own pay. You’ll take the money anyway — unplanned, in dribbles — and the reserve dies quietly in December.
• Betting the whole plan on snow. Count contract plowing in full, per-push at half, hope at zero.
• Keeping the reserve in the operating account. Operating cash gets spent — a trailer deal too good to pass up, a payroll pinch on the 14th. Separate account, separate login, no debit card.
• Having no plan except the card. When the reserve doesn’t exist, February gets financed at whatever your card charges — the Federal Reserve’s G.19 release puts average credit-card rates above 20%. A $13,200 month riding on plastic at that rate costs more than $220 a month in interest before you’ve repaid a dime of it.

What if the season’s half over?

Same math, shorter runway, bigger skim. And if the remaining months can’t cover it, you know now instead of in January — time to push fall work, collect receivables hard, or line up a working-capital cushion while you still look bankable. This calendar is also a standard page of the audit deliverable — the sample audit report shows the 12-month cash model built from an operator’s real numbers.

Three questions operators ask

How much should a lawn care business save for winter?

Enough to cover your fixed overhead plus your own pay for every month with no revenue, plus a cushion. The worked example on this page: ($7,200 overhead + $6,000 owner pay) × 3 zero-revenue months + $4,000 cushion = $43,600. Your overhead, your draw, and the length of your dead season set your number — the formula stays the same.

When should I start banking the winter reserve?

The first strong collection month of the season — May or June for most operations. Divide the reserve by the strong months left and move that amount the day collections land: $43,600 across six good months is $7,270 a month. Wait until August and you have three months left, so the same reserve takes about $14,500 a month — double the pain for the same winter.

Where should I keep the winter reserve?

In a separate account — a plain business savings or money-market account works — not in operating, and not invested. Operating cash gets spent, and markets pick their own timing. The job of this money is to exist in February, not to earn a return.
