Season pricing

Cuts per year

~52/yr weekly (warm climates) · ~26/yr biweekly · ~28–30/yr a typical cold/temperate season. Enter your own — it varies sharply by region.

Price per cut

Your price for one mow — a typical small lot runs $28–$55; adjust to your market.

Add-ons

Add the full-season cost of each extra service (fertilization, aeration, leaf cleanup). Leave blank rows empty.

Plan terms

Prepay discount

Optional prepay / annual-contract discount. Operators commonly offer 5–10% for pay-in-full — your call, defaults to none.

Round monthly up to

Round the monthly up to a tidy number for cash-flow cushion; the final payment trues up so the payments still add to the annual total exactly.

Billing window

12 months · year-round Active season

Active-season months

The mowing months to bill equally across (1–12).

First payment month

Sets the schedule row dates. Display only — the math is start-month-independent.

12-month spreads the cost year-round, even in winter. Active-season bills equally only across the months you mow.

How this is calculated

The annual total is the season bundle minus an optional prepay discount, then spread into equal payments across your billing window:

seasonMowing = cutsPerYear × pricePerCut
addOns       = Σ(annual add-on amounts)
annualTotal  = (seasonMowing + addOns) × (1 − discount)
monthly      = annualTotal ÷ billingMonths

Round-up + true-up. When you round the monthly up to the next $1 or $5 (a cash-flow cushion), the final payment absorbs the remainder so every payment still re-sums to the annual total exactly:

roundedMonthly = ceil(monthly to $1 or $5)   // months 1…N−1
trueUpFinal    = annualTotal − roundedMonthly × (N − 1)   // final month
Σ payments     = annualTotal   ✓ (the honesty check)

Two billing windows. 12-month spreads the season across a full year (flat winter and summer); active-season bills equally only across the months you mow. Flat vs pay-per-visit view shows the same flat monthly beside a peak mowing month and a zero off-season month.

This is level / "budget" billing — the same idea utilities use to smooth a seasonal bill. The discount and round-up are your business choices; the tool never assumes them. It is an illustration, not a billing engine.
