Oh a trick question -
"Money", very little as even what was collected in taxes was largely kept / spent in India, by the EIC agents, Army (~ 40% of tax revenue), or spent on local works (~ £400,000,000 between 1870-1930), rents, goods, bribes, Churches and the like. The local coinage had little value outside of the region it was collected in. If you turned up in Britain with a pocket full of: Bengal: Rupees, Anna, pice, pie;
Madras: Pagodas, Fanams, Cash;
Canton Tales,
Bengkulu dollars; Bombay: Rupees, anna, pice, paisa;
Mocha dollars,
Travancore: Fanams..... your options for spending / exchanging them would be rather limited, so the
"Money" largely stayed in the region of India it was minted in, though a few coins can be found in a number of British museums and collections. As to how much was robbed, the perpetrator not identified and taken out the country, I'd say virtually none, as any smart thief would convert the money into something exchangeable outside of the sub-continent.
FYI: The value of the goods TRADED from / to India is well documented and publicly available eg.
and there have been numerous books and papers that attempt to estimate net flows over the period, but typically they give conclusions along the lines of:
research suggests that from about 1870 to 1930 Britain took about 1% of India's wealth per year.
in goods rather than cash. Also a favourite one, the value of cloth imports and exports, under the EIC:
Alternatively if you take simplistic / theoretical / populist approach you'll get an answer along the following lines:
- In 1700: India's population has been estimated at 165 million (27% of The World's), with a GDP of $90.75 bn (22.6% of The World's), or $550 per capita (92% of China's).
- In 1947: India's population (before partition) was approximately 415 million (17.3% of The World's), with a GDP $258.164 bn (5% of The World's), or $622 per capita (130% of China's).
- In 2008: India + Bangladesh + Pakistan had a combined population around 1.621 billion (22% of The World's), with a GDP of $3,979 bn (8% of The World's), $2,454 per capita (36% of China's)
So assuming the British hadn't replaced the Mughals, and India could have maintained it's 27% share or the World population, in 1946 it should have had a population of 700 million, not 415. So that's 285 million people and $157 bn/year, for starters, then multiply the number by the number of lost generations / years, and you obtain some big numbers.
Similarly if India had maintained its GDP share, with it could have achieved with it's native technologies, with a population of between 2 and 2.2bn, in 1947 (land and diseases permitting), you're looking at 1.6 to 1.8bn bodies that need to be accounted for and $990 bn/year, multiplying back the numbers get very big.
Going further and if the Mughal and Maratha empires had decided to build 100's of IIT in mid 1700's, rather than fight each other, and suck up to the Britishers, the numbers get very, very, very big.
Or looking at it numerically:
- 415 million > 165 million citizens
- $258.164 bn > $90.75 bn/year GDP
- $622 > $550 per capita.
