PCB layout or Artwork Cost Estimation in Rupees(Indian currancy)

[scriptx007]

Hello Every body . i want to know how to estimate the cost of PCB layout or Artwork design which is designed in Softwares such as O*rcad , P*rotel .

I m intersted in knowing the PCB artwork or layout cost , not PCB manufacturing Cost .

For estimating cost of any product there are basic three parameters to be considered. 1 Manufactured quantity in Nos 2 Resources put in manufacturing. 3 Estimated profit per unit in % of manufacturing cost.
For PCB design No1 parameter will be a few trial layouts making trial pcb's from them proving them. No 2 parameter will be of importance A) The software cost B)Man hours spend to design the layout c)Man hour rate.
Now it is simple mathematics

can u give me a simple example

Dear Scripx007,

Sorry for the delay of reply.

To calculate the rate of PCB let us assume following things.

1)One PCB layout will take 5 redraws.
2)The cost of the software is RS. 48000.
3)The software will last for 4 years before upgrade / replace.
4)Time required to draw a 10cm x 10 cm PCB will be 8 hours.
5)Daily wedge of the worker is Rs. 120.-------- @ 1
6)Rent of the the place is Rs 2500.
7)Daily transport charge Rs.60.------------ @ 2
8)Daily supervisory charge Rs. 200.-------- @ 3
9)Daily Electric charges. Rs. 15 ---------- @ 4
10)There are 25 days in a month.

Now let us bring everything to daily basis

A)The software cost
per year: 48000 / 4= 12000.
per month : 12000 / 4= 1000
per day : 1000 / 25= 40.------ @ 5

B)Rent per day : 2500 / 25= 100 -------- @ 6

Now adding all @
120 + 60 + 200 + 15 + 40 = 435 Rs.

At profit of 20% 435 x 0.2 = 87 Rs.

So daily expenditures = 522 Rs.

As in a day 10cm x 10cm = 100 cm^2 PCB layout will be made
Per cm^2 cost is Rs. 5.22 as 5 redraws are considered this will go to Rs 5.22 x 5 = 25.10

I use a formula to determine best estimate on PCB layout using your ascii format net list and parts list - it has proven quite accurate for layout with stable schematic reference. Will glad to process if information is available.

Satish NAsik it is quiet helpful.
