Waterloo vs UNSW
MMath Data Science · Waterloo, ON vs Master of Data Science and Decisions · Sydney
Last reviewed: 2026-10-01
Short answer: University of Waterloo (MMath Data Science) is the cheaper program overall, reports the higher starting salary, pays back fastest against the standard ₹8L India baseline and currently has the stronger post-study work / visa pathway. So one programme wins on every measure here. That is worth knowing and it is still not the whole decision - none of these figures speak to your admit odds, and a specific lab, supervisor or city can outweigh all of them.

University of Waterloo: the honest note
Strong co-op and tech-recruiting culture; PGWP up to 3 years supports a solid migration pathway.
UNSW Sydney: the honest note
Widely marketed by agents; Sydney's cost of living and the 2026 485-visa tightening both cut into ROI - verify actual placement rates independently.
How payback is calculated
Payback = total program cost ÷ (annual savings abroad − annual savings staying in India), where savings are salary minus destination tax and a year's living cost. It is before loan interest. The India side uses a ₹8,00,000 baseline salary, taxed, minus India living cost. The baseline rises for IIT/NIT-class graduates, which lengthens payback for those students on both programs above. Full formula and worked example in the payback period guide.
