I measured out 16,000 sq ft for a restaurant that needs mulching. I came up with 90 cu yds. Tell me if this is correct for that much sq ft. The price I came up with was

90yd x \$65 per yd = \$5,850 total

how i got cu yd estimate.

16,000 sq ft x .16 then divide that by 27 = 95 but im figuring i should only get about 80-85 since theres alot of shrubs and landscaping in the beds.

HI JUSTIN
HERE IS A WEB-SIT THAT HAS A MULCH CALCULATOR ON IT WWW.MULCH.COM GO ON WEAR IT HAS PROFESSIONAL THIN GO ON THE
CALCULATOR LET ME KNOW IF THIS HELPS ROBERT

Use my formula,, works very well.

Length x Width x Inches(how thick you want it)
20' x 20' x 6" = 2400
2400/10 = 240
240/27= 8.9 cubic yards

this allows for a 20% compaction cushion. JUST ADJUST YOUR NUMBERS INTO THE ABOVE

Try using

Length x Width x Inches (How thick you want it)

Take that number divide by 10 then take that number and divide by 27
This give you your cubic yards allowing for a 20% compaction cushion

15' x 25' x 4" = 1500
1500/10=150
150/27= 5.5 cubic yards

We always figure on 3" of mulch for depth. A quick rule of thumb that we use in the field is sqft./100 = yds needed. It's not an exact number, and should put you just a little over what is needed to cover yourself.

i would agree with paponte, that is how i estamate mulch so 16,000 sqf you would need a least 160 yards i would eastamate 175 just to give you a buffer
and 175 x 65 = 11375

big differance

I don't put down much mulch, but did a job last Saturday -- small, only four cu yds. Since I don't do much, my "eye" does not gain much experience for making future estimates.

But, I always make a good estimate beforehand of area and some "coverage ratio." For me, that term means the density of beds, either few plantings (near 1.00), or densely planted (maybe as low as 0.50). When I'm done with the job, and know how much material I really needed, I back calculate the depth of mulch just spread.

Initially, I estimate 1.5" depth. Afterwards, I know more precisely how deep I really spread the material. If it is a job that only needed a freshening up, the depth is a small number; if the soil is bare or nearly bare, the depth is a larger number.

Gaining some backlog of jobs done is a big help to making estimates for future jobs. Frankly, I'm surprised how well the estimates usually are fulfilled when the project is done.

Obviously, my approach is unreasonable for 16K sq ft jobs.

The formula I use is very simple and is usually right on target.
Divide 16,000 by 3 to get your sq yards, then devide that by 80.
I come up with 66.666 cubic yards, then round up to 67.

OK 3 differnet guys, 2 different ways. the yare way off of each other. One has 175 yds on 16000 sq. ft the other has only 67 yds. WTF??????
Maybe it's because the 3rd guy didn't go w' depth and where did he get 80 from?
