Hey guys help me out here. I am pricing a mulch job for 6700 sq. ft. If I do the math I should be able to cover 162 sq. ft. per yard (2 inches deep). The price sheet that I have from my local supplier has a foot note that 1 yard will cover approx. 100 sq. ft. 2 inches deep. That's a huge discrepency when trying to accurately price this job. I know when buying mulch in bulk sometimes you get a little less and sometimes you get a little more. If I go by my estimate I should need about 42 yard. If I go by the supplier estimate I will need about 67 yards. Go figure! Any advice would be appreciated.

42 yards is the correct amount. if theres plants and other things that take up space you can factor that in.

mulch formula is
yards = (inches of mulch thickness / 12) X sq ft then divide that by 27.

You would need 20.6 yds / inch you apply. I'm not sure about your supplier's price sheet except maybe they're trying to sell extra mulch. A yard covers 80 sq. ft at 4" thick (roughly.) I'd go with your 42 yd. estimate and if you need more then I'd be talking to your supplier and if need be have him come out and do the measurements himself and let him explain his special formula for figuring yds.

Are you sure you read the suppliers price sheet correct? I suspect either you read it wrong, or they have a typo...... a "simple" calculation is
1 yard 3" 100 sf
1 yard 2" 200 sf
1 yard 1" 300 sf
I know its not exact, but it is simple math that people can easily compute and get pretty close.

I think Raymond is correct. The supplier is trying to sell more mulch assuming the average Joe doesn't know any better. I have purchased from them before for much smaller jobs and I always felt the "load" was generous. They must be using the Washington D.C. "fuzzy math"!!

What was I thinking.... 2" is wrong above, I must be asleep... 1 yard 2" 150 sf

I have a spreadsheet that figures it for me... or try this

Square Feet x Depth = Cubic Feet then divide by 27= Yard(s)

(6700 X 0.16) / 27 = 39.70

Factors for Depth Inches:

1 inch Depth multiply by .08
2 inches Depth multiply by .16
3 inches Depth multiply by .25
4 inches Depth multiply by .33

Thats more like it

The place i get my bulk mulch at uses a one yard bucket but that's the struck volume of it. They always heap it as much as it will hold, so I can only get 6 yards in my 8 yard dump trailer or about 1/3 more than I pay for. So I don't feel bad about taking one wheelbarrow out of each load for "product evaluation" and using it at my place ;)

The density of the plantings can make a big difference in how much mulch you'll go through, but 2 inches is a good average depth to use if they replenish it annually.

your estimate of 42 should be correct. 67 is crazy

Same thing I got.

To me this is easier when doing depth in inches

lenght [in feet] x widht [in feet] x depth [in inches] / 324

to me this is easier than trying to take depth in inches and dividing that by 12

If the beds are full of shrubs, ground-cover, flowers, etc, you will use less mulch. If you are going over existing mulch, you can also use less than if it is the first time a bed is mulched. I like to put down a solid 3" if it is a new empty bed.

So I usually sell people 1 yard per 100 sq/ft if is the fist time mulched, and it is a wide open bed. But I will go to 1 yard per 200 sq/ft if it is just a thin coat over existing mulch.

Someone else said something similar but I do LxW/300. That will give you how much you need to put one inch down. That is a little heavy on the amount. Then you just double the number for two inches, triple it for three and so on. 42 is the correct answer I'm sure, but I come out with 44 doing it my way. It gives you a little room for error and if you don't need it all you are doing ok.

i think your supply yard may be off a little.....If you would even want 3 in. thick you would only be needing 62. They are still trying to give you 5 more yards.....someone's calculator is broke

one yard covers a 10x10 area 3'' deep for 6700 sq. ft you need to determine how thick you want to apply it if you want to go 2 inches you need 39.7 or 40 yds of product, so lets say bid for 45- 48 yards to give youself a buffer incase you made a slight mistake meausring, remember any additional material you buy comes out of your profit.

Yeah I come up with 42 yds. myeslf. I don't know about pricing something that large tho. Most I've ever done is 11 yds. I am charging $120 per yard installed including all prep work. Something that large tho I'd personally probably shoot for atleast $90 a yard if its open area for the most part... Just my 2 cents...

Are you blending this in with existing mulch?
2" on a new bed is a bit skimpy.
