Dhaka and Kolkata sit 162 miles apart on the Bengal Delta and share the Bengali language across the international border. Dhaka runs 21 million in the metro on the garment export economy; Kolkata runs 15 million on the eastern Indian corporate stack at Salt Lake Sector V and the Park Street financial belt. Kolkata is 22 percent cheaper across the cost line, 1.8 points safer on the index, and runs the deeper IT employer base.
The two cities answer different questions. The headline number resolves the index; the breakdown resolves the fit.
Kolkata wins on the cost line by 22 percent across twelve of twelve categories, the safety axis by 1.8 points overall on the lower violent crime rate at the central wards, the public transit density that the Metro Line 1 plus the suburban rail stack runs at 4.3 million daily passengers, and the salary curve at the senior engineer role by 38 percent. Dhaka wins on the gross GDP growth rate at 5.9 percent against the West Bengal 4.4 percent, the garment export economy that anchors 4.4 million jobs at the Ashulia and Gazipur industrial belt, and the entry level remittance pathway through the Middle East corridor. The structural read favors Kolkata for the foreign professional and Dhaka for the regional manufacturing operator.
Kolkata scored 6.4 on the everycity index in 2026, Dhaka scored 5.6. The headline gap is 0.8 points. For the long form, see the Dhaka city profile and the Kolkata city profile.
The cleanest decision rule we have found: if the work is in technology, the eastern Indian IT corridor, the corporate finance role at the Park Street tier, the international school for the family on a budget below 12,000 dollars a year, or the senior professional with the Indian employment authorization, Kolkata is the math. If the work is in the garment manufacturing operator role, the regional NGO and development sector, the diplomatic posting at the Gulshan diplomatic enclave, or the entry into the Bangladeshi remittance economy through a registered employer, Dhaka is the math.
For the regional context, both cities anchor Asia at the South Asian megacity tier. For the country level read on the Indian side, see India. For the broader comparison set within the region, see Dhaka vs Mumbai, Bangalore vs Mumbai, and Chennai vs Mumbai. The cheapest large cities ranking places Kolkata at number 18 globally and Dhaka at number 9.
Twelve line items priced in May 2026 for a single resident in a central one bedroom. Green text marks the cheaper city per line.
Kolkata is cheaper on twelve of twelve lines. The rent gap is 45 dollars on a central one bedroom and 100 dollars on a family three bedroom, which compounds across a 12 month lease into 1,200 dollars of preserved capital. The Dhaka rent line carries the structural premium of the Gulshan, Banani, and Baridhara diplomatic enclaves, which trade at 3.4 times the median Dhaka neighborhood rate. The Kolkata rent line is held flat by the rent control act that the West Bengal government enforces across the Bow Bazar, Beck Bagan, and Hindustan Park stack.
The 22 percent overall cost discount in Kolkata is consistent with the broader India to Bangladesh price gradient that has run in this band since the 2023 taka devaluation. The Bangladesh taka has lost 14 percent against the Indian rupee since the January 2024 baseline, but local price inflation in Dhaka at 9.2 percent annualized erased the foreign currency advantage for the expatriate paid in taka. The dollar paid expatriate sees the same purchasing power within 2 percent in both cities.
For the international transfer math, Wise handles the BDT and INR conversion at within 0.7 percent of the mid market rate, well below the 3 to 5 percent the regional retail banks apply. The cost converter tool takes your salary in either direction. BProperty and Bikroy anchor the Dhaka listing market; 99acres and MagicBricks cover the Kolkata stack.
The 10 point safety read across the five sub axes the methodology weights equally.
Kolkata wins safety on five of five sub axes by a margin of 1.2 to 2.0 points. The 8.4 Kolkata overall sits at the top three South Asian capital tier alongside Colombo and Bhutan; Dhaka at 6.6 underperforms on the after dark axis at the Old Dhaka ward and the Mohakhali bus terminal, the political demonstration risk at the Shahbag square, and the road traffic death rate at 21 per 100,000 against the Kolkata 8.4.
For the new arrival, SafetyWing covers the first six months in either at 42 to 58 dollars a month for the under 40 single. The safest cities ranking places Kolkata at number 84 in Asia and Dhaka at number 142.
Healthcare quality. Dhaka runs the public hospital network at minimal cost for the Bangladeshi national with the private extension at Square, United, and Apollo Hospitals; the medical evacuation pathway to Bangkok runs in 4 hours through Suvarnabhumi for any procedure outside the local capability set. Kolkata runs the public system at near zero cost for the Indian national with the private network at Apollo Gleneagles, Fortis, AMRI, and Belle Vue Clinic that runs at 24 to 38 percent of the Singapore equivalent for comparable procedures and serves as the eastern Indian medical tourism hub for Bangladesh, Bhutan, and Nepal.
Annual averages, the worst month, and the count of days in the comfort band.
Both cities run the tropical savanna profile with a six month monsoon window from June through October. Dhaka takes 128 rainy days against the Kolkata 118 and the higher humidity loading at 77 percent against 74 percent, which compounds the heat index in May at 109F against the Kolkata 105F. Kolkata wins on the absolute summer peak by 4F and the sunshine hours by 280, but loses the winter low by 3F. The structural climate read favors Kolkata for the temperature moderation and Dhaka for the marginally cooler peak.
The climate match tool finds cities with similar profiles. Both cities pair with Mumbai and Ho Chi Minh City on the tropical savanna axis. The warm winters ranking places Dhaka inside the global top 60 and Kolkata at number 78.
Air quality. Dhaka PM2.5 averages 78 micrograms year round and pushes 220 in the January burn season at the brick kiln belt north of the city; Kolkata averages 52 micrograms with the November to February stack pushing 120 on the agricultural burn import from the Punjab corridor. Both rank in the worst 20 globally for ambient particulate. The clean air ranking places Kolkata outside the top 200 globally and Dhaka outside the top 280; the air purifier and the N95 mask are the structural household items in either.
Median salaries for three mid level roles, the headline tax band, and the effective rate after standard deductions.
Kolkata pays 32 to 62 percent more on gross salary for comparable mid level engineering and finance roles, off the deeper corporate base anchored at the Salt Lake Sector V technology park, the Kolkata Stock Exchange listed name set, the eastern Indian regional offices of TCS, Wipro, Infosys, IBM, and Cognizant, and the diplomatic corps presence at the consular district. The Dhaka salary curve has lifted 18 percent since 2021 on the garment manufacturing nearshoring inflow but trails Kolkata at the senior professional tier by structural measure.
Tax. Bangladesh runs a top marginal rate of 25 percent on income above 1.65 million taka with the effective rate at 18 percent on the 50,000 dollar earner. India runs a top rate of 30 percent on income above 1.5 million rupees with the new tax regime offering a higher exemption threshold and the effective rate at 22 percent on the same income point. The tax calculator tool runs your number against either jurisdiction.
The major employers in Dhaka are Beximco, Square Group, Pran RFL, Akij Group, Grameenphone, the Bangladesh Bank, the central regional offices of Unilever and Standard Chartered, and the development sector anchor of BRAC and Grameen Bank. The major employers in Kolkata are TCS Salt Lake, ITC Limited, CESC, Coal India, the State Bank of India eastern circle, Wipro, Cognizant, IBM, and the Kolkata Port Trust.
The qualitative axes scored on the same 10 point scale the index uses elsewhere.
Kolkata wins lifestyle on five of five sub axes. The Kolkata food scene at the Bengali sweet stack, the Park Street fine dining belt, the Mughlai biryani tradition at the New Market quarter, and the street food density at Decker Lane sits at the deepest in eastern South Asia and at the global top 25. The foodies ranking places Kolkata at number 22 globally and Dhaka at number 64.
Cultural density favors Kolkata at the Indian Museum, the Victoria Memorial, the Academy of Fine Arts, the Kalighat painting tradition, the durga puja at the September pandal calendar, and the literary anchor at the Bengali language publishing tier. Dhaka offers the Liberation War Museum, the Lalbagh Fort, and the boishakhi mela calendar but operates at a thinner depth on the institutional axis. The eating Kolkata versus Dhaka guide walks the regional cuisine ladder.
The boring section that decides whether the move actually happens.
Visa difficulty separates them by one point. Bangladesh runs the E visa and the Work Permit at the standard pathway through the Board of Investment with the sponsor company filing on the foreign employee behalf at 6 of 10 difficulty. India runs the Employment visa at the 100,000 dollar minimum annual remuneration threshold for the foreign professional and a 1 to 5 year validity at 7 of 10. The 2026 visa guide covers both. The easiest visa cities ranking places neither inside the top 100, since neither runs a dedicated digital nomad pathway as of May 2026.
Working language. Dhaka operates in Bengali at every administrative tier, the apartment lease signing, and the daily transaction; English coverage runs at the multinational corporate tier, the diplomatic enclave, and the NGO development sector. Kolkata operates in Bengali at the local administrative tier with Hindi at the second tier and English at the IT corridor, the corporate offices, and the international school stack. The Kolkata bilingual coverage is structurally wider at the professional tier than the Dhaka equivalent.
Healthcare access. Dhaka runs the public network at minimal cost and the private network at Square, United, and Apollo; the bilingual coverage runs uniform at the private tier. Kolkata runs the public network for the Indian national and the private network at Apollo Gleneagles and Fortis at 35 percent of the Singapore equivalent. The SafetyWing bridge covers the gap between arrival and the local insurance enrollment.
Education. Dhaka runs the international school stack at 8,000 to 18,000 dollars a year across the International School Dhaka, the American International School Dhaka, the Aga Khan School, and Scholastica. Kolkata runs the international stack at 6,000 to 14,000 dollars a year across the Calcutta International School, La Martiniere, the Modern High School, and the Heritage School. The state school pathway is feasible in either at the Bengali language level but not a practical option for the foreign resident at the structural level. The relocating with kids guide walks the wait list patterns.
Move logistics. The shipping container math from North America runs 5,800 to 8,400 dollars on a 20 foot to either; the customs clearance runs through the Chittagong Port for Dhaka at 7 to 14 days and Kolkata Port Trust at 5 to 9 days. The pet relocation timeline is 4 months for Bangladesh off the rabies titer schedule and 5 months for India off the AQCS import permit lead time. The relocation checklist covers both.
For the technology professional at the senior engineer or above, the corporate finance role at the Park Street tier, the family weighting the institutional school stack and the cost line below 600 dollars a month, and the resident at the salary line above 24,000 dollars who can absorb the eastern Indian living cost, Kolkata wins. The salary delta survives the cost delta and the corporate stack runs deeper across the eastern Indian IT corridor.
For the garment manufacturing operator, the development sector professional at the BRAC or UNDP tier, the diplomatic posting at the Gulshan enclave, or the entry into the Bangladesh remittance economy through a registered employer, Dhaka wins on the sector specific axis. The structural growth rate at 5.9 percent versus the West Bengal 4.4 percent compounds over the 5 year horizon.
