If 8.3 tons is launched to GTO as an ultra heavy communications satellite e.g. the cost is $ 7470/kg. This is without passing on any cost savings because of first stage & payload fairing reuse as it's still a work in process.
The GSLV Mk 2 in comparison (figures again from Wiki) can launch 2.5 tons to GTO and costs Rs 220 crores ($ 36 million) per launch. That works out to $14,400/kg. I doubt whether the GLSV Mk 3 cost/kg will be significantly different.
As far as each country being treated as a silo for launch business, because costs were not significantly different across launchers, launch customers gravitated towards a homegrown solution. (Also there is some protection in the business undoubtedly). But if as Musk says that costs can be reduced by as much as 75% with only first stage and payload fairing reuse, then SpaceX has a significant ability to be flexible on pricing and attract customers currently using other launchers.
ISRO should work on the RLV which they have been talking about, it's the only way to reduce launch costs. Space launch EMAL etc. maybe after 50-80 years.

Gist of it almost looks like musk wanting to do a Jio on the space launch business.
One kaboom they had in 2015 on the launchpad had their year go a quarter billion dollars in the negative.
For me, whenever I visit this thread and see the 'discussion' on mass fraction and clustering,all Cryo, competition is doing this and that, ISRO underperforming and customary bah and pah being thrown at ISRO.. I think of it as a newbie coming and saying, Lockheed Martin flew Raptor in the 90s is now on the F35, stealth is uber, therefore ADA/DRDO/HAL/LCA hai hai.
June 5th is a very important date when the GSLV mk3 will be proving it's operational capability.
It's the first flight of this specific Cryo engine.
Before people throw brochure numbers, it's important to look at the time taken to realise both the cryos for the GSLV series.all these years of hard work and toil have given us this technology which will need a few more years and flights to declare reliably operational.
We still have a way to go in mass production of these launch vehicles to realise economies of scale.
@the spacex figure of 7,000 odd per kg for falcon 9 and GSLV mk2 figure of 14,000 odd per kg - an important thing to note is, GSLV cost figures are in line with ULA vehicles which don't use solids or 'lug' dead weight. Please reference the article above for spacex vs ULA costs..
I'm quoting from the article, they had a projection of 55 million operating profit on 1.8 billion revenue based on 20 launches for the year.They managed all of 8 launches.
Either ways it's just 3% operating profit on revenues.
My point is having uber mass fraction or technology isn't a guarantee of success or profitability.Also their business and what ISRO does are fundamentally different things.
One is for profit and the other is for realising technologies indigenously and achieving strategic autonomy in the space business.Antrix and its profits are a by product.
The constant Rona dhona on the thread and spread sheet rocketry solutions of 10 ton to GTO become tiresome.
It's easy to compare ISP values of solids vs cryos.
Or which configuration has best "mass fraction".
The person making the comparison and pooh pooing ISRO should make the effort to list the R&D costs involved behind those uber rockets and the paltry budgets ISRO works with.
Suddenly it'll start making sense, how ridiculous the mass fraction and isp number crunching is.
Anyway, I look forward to 'raakit ki garajna' on the 5th of June.Its going to be a historic day for ISRO and Desh !
(Shoddy camera work expected as usual and a couple of articles on India's sanitation and poverty too,briturds aid discussion etc.im ready for all of it
I wish I could be at Pulicat lake for the launch,will have to miss this golden opportunity though.
