Mulch Installation Pricing Calculator
Work out what to charge for a mulch job: cubic yards from the beds you measured, spreading time at your own access, delivery, bed prep, disposal and margin.
How this is calculated
Volume first, then time, then money. The beds you measured and the depth you set give the cubic yards; the over-order buffer sits on top of that number and, deliberately, on the spreading time too, because every yard that comes off the truck is a yard somebody wheels. Access multiplies the spreading only. Drive time lands in your cost in full and in the charge only for the share you choose to bill.
finishedCuFt = area × depth ÷ 12
finishedCuYd = finishedCuFt ÷ 27
orderCuYd = finishedCuYd × (1 + buffer)
coverage = 324 ÷ depth (sq ft one cubic yard covers)
bags = ceil(orderCuFt ÷ bagSize) (bagged only)
spread = orderCuYd × spreadRate × accessFactor
onSite = spread + bedPrep + edging + removal* + extra (*if stripping)
crewHours = onSite × crewSize
driveCrew = driveHours × crewSize
labour = (crewHours + driveCrew × driveBillPct) × chargeRate
mulch = orderCuYd × pricePerCuYd (or bags × pricePerBag)
materials = (mulch + delivery + disposal) × (1 + markup)
quote = max(labour + materials + addOns, jobMinimum)
perCuYd = quote ÷ orderCuYd
tax = quote × taxRate
cost = (crewHours + driveCrew) × costRate + materialsAtCost
margin = (quote − cost) ÷ quoteWorked example, the one the unit tests pin. 1,296 sq ft of beds at 3 in is 324 cubic feet, which is exactly 12 cubic yards; a 5% buffer makes the order 12.6. At one hour a yard with a 1.25 access factor that is 15.75 hours of spreading for one person, plus 1.5 hours of weeding and an hour of edging, so 18.25 hours each and 36.5 crew-hours for two, with a further hour of paid drive. At $55 a crew-hour that is $2,007.50 of labour; 12.6 yards at $45 plus an $85 delivery, marked up 20%, is $782.40; the quote lands at $2,789.90 before tax, which is $221.42 per cubic yard installed and $74.40 per paid crew-hour. Put $38 a crew-hour of cost against it and the realised margin is 25.6%.
The coverage identity is arithmetic, not an opinion. A cubic yard is 27 cubic feet, so spread one inch deep it covers 27 × 12 = 324 square feet. Divide by your depth and you get the coverage line the page prints: 108 sq ft at 3 in, 162 at 2 in, 81 at 4 in. That is the same identity the mulch calculator uses, which is why a cubic-yard figure carries straight between the two pages.
The spread rate and the access factors are placeholders. Nothing published states how long a person takes to move a yard of mulch, and it is not one number anyway: barrow distance, bed shape, plant density and whether the pile can be dumped beside the bed all move it. The access select seeds the multiplier box and a number you type over it survives a later change of select. Time your own jobs and replace both.
The buffer is not free. The page prints the extra cubic yards the buffer buys and the crew-hours that come with them, because the over-order shows up in two places and most quotes only notice one.
The margin check is all-or-nothing. With no cost per crew-hour the labour half of the job cost is unknown, so reporting a margin off the materials line alone would flatter every quote. Fill the box and the block appears; leave it empty and it stays hidden.

What this prices, and what it deliberately does not
A mulch job is a volume problem wearing a labour problem’s clothes. The material is easy to count and the spreading is not, because the same twelve yards can be a two-hour tailgate job or most of a day through a side gate with one barrow. This calculator builds the quote from both halves, then runs the two checks a flat per-yard price hides: what the job returns per paid crew-hour, and what the realised margin is once the crew’s loaded cost is set against it.
It is the pricing rung of a two-page job. The mulch calculator answers the quantity question in cubic yards, cubic feet and bags. This page reuses that page’s conventions on purpose, bed area in square feet, depth in inches, area by depth to cubic feet and then cubic yards, so a number carries straight across without converting anything.
Every money field starts empty on purpose
Search for a mulch price per yard and you will find plenty of numbers. Follow them and they resolve to homeowner lead-generation directories quoting each other, with no regulator, trade body or published survey behind them. Under this site’s cite-or-omit rule that means the tool ships with none of them, and it never presents a rate as a market fact.
The four pre-filled figures are all quantities or scoping conventions, and all of them are editable: the 3 inch depth the mulch calculator defaults to for a new bed, a 5% over-order buffer, an access multiplier and a spread rate in hours per cubic yard. None of them is a benchmark. The spread rate in particular is a placeholder until you time your own crew, because nothing published states how long a person takes to move a yard of mulch and it would not be one number if it did.
The coverage identity, so you can check the volume in your head
A cubic yard is 27 cubic feet, so spread one inch deep it covers 27 by 12, which is 324 square feet. Divide by your depth and you have the coverage the page prints beside the volume: 108 square feet at 3 inches, 162 at 2 inches, 81 at 4 inches. That is arithmetic rather than an opinion, and it is the same identity the mulch calculator uses, which is why a yard figure moves between the two pages unchanged.
The buffer buys material and labour, both
Most quantity calculators stop at the order. This one carries the over-order through to the time, because every yard that comes off the truck is a yard somebody wheels, tips and rakes out. The page prints the extra cubic yards the buffer buys and the crew-hours that come with them, side by side, so the cost of ordering long is visible on both lines rather than just the invoice from the yard.
If the buffer keeps leaving you with a pile at the end of the day, the question is whether you should be buying differently at all. The bulk versus bagged material calculator compares the two supply routes on the same volume, which is the decision behind the price box on this page.
Access multiplies the spreading, and nothing else
The access factor is the honest version of “this one is awkward”. It multiplies the spread time only: bed prep, edging and old-mulch removal are entered directly as hours, so they already carry their own difficulty and would be double-counted if the factor touched them. The select seeds a starting multiplier and a number you type over it survives a later change of select, because a deliberate override should not be undone by a scoping change.
Stripping the old mulch is two costs
Turn the strip-out on and the tool adds removal hours to the crew time and a disposal fee to the materials, tracked separately because they fail separately. Old mulch holds water and is heavier than it looks, and a quote that prices the raking but forgets the tip fee is short on every job. Turn it off and both drop out of the quote rather than being silently summed.
Mulch usually rides with something else
Very few operators sell a mulch visit on its own. It is normally the back half of a cleanup, which is why the page has a standing-annual-re-mulch tick: mulch is the one landscape job that comes back on a calendar, and selling next year’s now is what turns a visit into an account. Price the front half in the spring cleanup pricing calculator, and when the property needs a full proposal rather than one line, the landscaping estimate calculator stacks mulch alongside the rest of the materials with labour and markup on top.
