- Update: I have received a number of requests for this spreadsheet. I have removed the Invoice page, but the main page is now available for a small fee here: rivalmachining.gumroad.com/l/...
Purchasing this helps support the channel!
I find that quoting is one of the hardest things to get right with running a job shop. This is how I quote my job shop work using a simple Excel spreadsheet. I know it could use more work, but I think I'm making progress on making accurate quotes.

Thank you for your video. It speaks to what goes on in a real shop.
Looks good, the only thing I would mention is the overhead on the customer copy is probably not a great idea as it will just lead to questions. Your hourly rate looks really low so I would just hide your cost there. It will make it easier for your customers to compare to other quotas as well. Keep the videos coming)
Thanks for the advice. I've been wondering about that.
You might want to look into HSM for feeds and speeds, he covers all material/cutters. This will reduce your learning curve on breaking end mills.
Wow excellent video. Super helpful. I don’t have a Tormach yet but within 6 months. I bought all the tooling first though. I am going to build the base and enclosure. 1100mx
Awesome, I'm glad you found it helpful. I bought my Series 3 right before they announced the M series. I could only mentally prepare myself for the cost of the Series 3, but the new machines sure look nice! I'd be interested to see your enclosure when it's done. The "fun" of my shower curtain setup has really worn off, but I don't want to pony up the $2400 for the Tormach enclosure. I've been kicking around the idea of making one out of square aluminum tubing and sheet metal but haven't come up with anything easy to build that I really like.
From what I've learned, tool life typically lasts about 15 minutes of contact with the material while its doing the cutting. At least that's how long the life of corners on inserts are rated for when being developed by the tooling company, provided that the speeds, feeds, and depth of cut are optimal.
Thanks, I think there are a lot of factors, mainly the cutter and workpiece materials. I would think carbide cutting aluminum would last longer.
Sweet video, you just added one more subscriber. Hire a cpa to do you're taxes, you will be able to take advantage of several benefits. Home office, business expenses, you're power, water, the cost of the machine and the list goes on.
Thanks for subscribing! I probably should hire a CPA. I probably will in the next few years.
Hi you might not like our thoughts but it is some strange advise and is shared with our best intentions from these two guys of (BACKGROUND) the CNC aerospace job shop past as well as a computer controller card to OEM maker with software. Knowing what we could or could not do just take it and then figure out how to do it for that price. While it is good to know your internal costs (have to), pricing a part all comes down to what the market can or will bear. Just how we do things around here. We are in California one if not the most restrictive regulated and highest taxed states in the country. For a baseline here we are currently only a home based shop just like you are. We only provide an hourly cost rate show a 7 to 10% markup (predicted profit) and once in the while we might depending on who, efforts and weights breakout out the programming or material maybe both and that is all. This is just what we do and some of what we have done in our pasts.
Thanks for the advice, I'll take what I can get. I completely agree that the accepted price will come down to the market forces. But, I don't know of a way to compare quotes with competitors, so its a little bit of guess work to get right. I've taken jobs and realized I underestimated the amount of work, and I've quoted jobs and never heard back. The trick is finding the happy medium. I like the idea of rolling labor and overhead into an hourly rate. I need to start tracking my hours so I know what that rate should be.
@@RivalMachining I am so glad you did not misread me as being bad to you, I only want you to succeed as I listened to you, you have a wife and many children so I am pulling for you. I should share that I hated quoting jobs for nearly 20 years but nothing more saddening then having to layoff employees because I might get too many jobs priced too high in a short amount of time causing this to happen, Happy New Year and thank you for sharing your strategy with us and many others I assure you that this is an issue that is large and very wide spread.
For threading holes. You might be able to get them threads done with a single point threadmill or a regular threadmill. That is if you dont have ridgid tapping on the threadmill. If you need I can pass you a program I have made for single point threading on a mill.
Thanks for the offer, since this video, I have purchased some single point threadmills and have them working with the help of John Saunders' videos and Fusion 360.
@@RivalMachining awesome glad to hear. Such a versatile tool to have at ones disposal.👍
Good video. I quote professionally and we don't show customers any of this. We give them a price for 1 pc (huge markup) 5pcs or less (medium mark up) and 10 or more which is the actual quote with a reasonable profit built in. Tapping sucks recommend you look into threadmilling. Quality threadmills are expensive but with reasonable feeds and speeds they last for a very long time. Also process reliability is MUCH better and while a threadmill is making perfect threads you can be working on other tasks.
That is a good point about quoting in quantities. I could probably simply add a few columns for the expenses that change with quantity and get multiple prices at once. I don't think I can threadmill because my spindle doesn't have feedback. Tormach makes a compression head that is supposed to compensate for any spindle speed error that I might buy. I kind of like the idea of a tapping arm so the machine can be running while I tap holes on the side.
@@RivalMachining Ya when you quote like that you're more likely to get larger orders also. It's also more fair to both you and your customer. Thread milling doesn't require an encoder. Basically a thread mill is an end mill in a different shape. When you running it you are really circle milling with a Z move at the same time. Machine tapping requires an encoder or a special tool when you lack one. This explains it much better then I can.

I have a lot to learn about thread milling. That video was really cool. I pictured thread milling being similar to cutting threads on a lathe, which I see now is completely incorrect. I will need to look more into it for sure!
@@RivalMachining ya Titan puts out some good video. cheers
Definitely look into threadmilling. The tormach can handle it. NYCCNC has some good information on this too.
Hey, great video! Very helpful series. You inspired me to get a CNC converted X2. You mentioned 100k garages. I signed up last week and my account still hasn't been approved. About how long did it take to receive your approval? I have everything filled out to the best of my knowledge. Thanks!
They must be monitoring this channel because I just got approved haha.
Thanks, I'm glad you like the channel! I had to contact them through Facebook to get my account finalized.
Dear sir,
Kindly help on below topic to run mechanical machining/sheet metal workshop.
a) How to calculate overheads and own costing of per hour
b) How to estimate cost of part from drawing given by customer. ie Rates to quote to client , which covers own labour cost, material and factory overheads.
I am running machine workshop at Mumbai -India with manual lathe, milling, drilling, bandsaw and welding machine.
Thanks ,
are you able to use the excel that efficiently as i tried it in 2017 and then dropped the development
Your spreadsheet has a small error in it. Under shipping, polybags is not included in the sub total. Also, I would suggest that you expand the range of the subtotals you have listed. For instance, the formula for the subtotal in shipping should read "=SUM(S3:S12)".
Thanks, I'll take a look!
Just out of curiosity, how do you go about finding jobs? Is it a situation where you’re finding yourself seeking work or do you find that those jobs come to you?
I find most jobs on 100kgarages.com but it can be slim at times and a lot of spam to sort through. Right now, I am typically looking for work. Every once in a while a job will come to me, but that's not typical.
Hi Dallas,
Did I miss it or is there still costs for "case hardening"/Heat treatment" to be added? If required of course.
That would be a good thing to add, maybe a finishing section to include anodizing, bead blasting, etc.
Hey man would you be willing to share your spreadsheet? Thank you!
Shoot me an email at dallas@rivalmachining.com and I'll send it to you.
yes you charge everything you think it cost and your labor time. if client accept it. then they can do it them self lol.thats how it work. dont try do parts too cheap like my bos. its not worth it.quicker quicker this job not worth it quicker. WHAT! if he sell part fpr buck why we do them lol. boss think if he sell cheap its better becouse he got that job LOL
