Okay, forgive me. I'm actually not a dummy, but after working the day job all week, my brain is just fried! I'm trying to create an Excel spreadsheet to help me in better estimating my jobs. (I'm actually kinda just thinking aloud here, but any input would of course be appreciated!)

I'm trying to calculate my operating expenses (equipment only), so I did a quick test in the back yard. Since I'm just using my current push mower for now, I'm a little slower than a lot of folks on their riders.

I plotted off an area about .01 acres (roughly 440 sq. ft.) I was able to mow this area in exactly 2 minutes.

I then did a second test, and calculated that my mower is using approximately 1 cup of gas in 11 minutes. Since there are 16 cups in a gallon, I'm using 5.45 cups, or .34 gallons, per hour.

So continuing with this way over-thought formula, I should be able to mow 1 acre in 200 minutes, and using 1.33 gallons of gas.

Okay, with that part out of the way - if my secret hourly rate is $35/hr (and let me know if that is about on track with the rest of you guys), a relatively standard half-acre, suburban subdivision residential lot would mean I'd spend about 100 minutes mowing, use .63 gallons of gas, and bill for $58.

For those of you whose heads have not already started leaking, does this seem overpriced to you? I can't imagine paying $58 per cut on my half acre lot. I figure since I'm not calculating the footprint of any structures on the property into the acreage, $58 would cover the extra time doing the detail work.

Am I even remotely close to on track? Many apologies for my long-winded post!
