Chattogram and Mumbai split the South Asian commercial port tier on different scales. Chattogram anchors Bangladesh at 3.20 million metropolitan residents and 92 percent of the national container throughput. Mumbai anchors India at 21.30 million metropolitan residents, the Bombay Stock Exchange and the National Stock Exchange combined market capitalization at 4.62 trillion dollars, and the Reserve Bank of India headquarters. The 1.8 point spread on the everycity index sits on capital markets depth and salary line against the lower Chattogram cost line.
The two cities answer different questions. The headline number resolves the index, the breakdown resolves the fit.
Mumbai wins on the Indian capital markets depth at 4.62 trillion dollars combined market capitalization, the salary line at 3.2 to 4.8 times the Chattogram rate on technology and finance roles, the Chhatrapati Shivaji Maharaj International Airport non stop route map at 92 destinations against the Chattogram Shah Amanat at 14 destinations, the deeper international expat base at Bandra, Worli, and Powai, and the Bollywood plus the broader Hindi cinema cultural output. Chattogram wins on the central one bedroom rent at 145 dollars against the Mumbai 685 dollars, the structurally lower congestion, the cleaner air at 56 micrograms PM2.5 against the Mumbai 64 micrograms, and the lower flood exposure at the Bay of Bengal versus Mumbai's annual June through September monsoon flooding at the SOBO and Andheri belt.
Chattogram scored 5.4 on the everycity index in 2026, Mumbai scored 7.2. The 1.8 point spread sits on capital markets depth, the salary line, the air access, and the cultural output for Mumbai against the lower rent line and the cleaner air for Chattogram. For the long form profiles, see the Chattogram city profile and the Mumbai city profile.
The decision rule we have settled on: if the work is at the Reserve Bank of India, HDFC Bank, ICICI Bank, the Tata Group corporate base, the Bombay Stock Exchange listed tier, the global investment bank India desk at Nariman Point, the Hindi cinema cluster on the Andheri Goregaon axis, or the technology unicorn tier at Powai and Bandra Kurla Complex, Mumbai is the math. If the work is at the Port of Chattogram, the readymade garment factories at the Chittagong Export Processing Zone, the BSRM Steels and GPH Ispat industrial cluster, the offshore oil and gas operators on the Bay of Bengal block tier, or the household weighting the cost line, Chattogram is the math.
For the regional context, both anchor the South Asian commercial tier alongside Kolkata, Dhaka, Colombo, and Karachi. The cheapest cities ranking places Chattogram at number 32 globally and Mumbai at number 124; the safest cities ranking places Mumbai at number 162 globally and Chattogram at number 268.
Twelve line items priced in May 2026 for a single resident in a central one bedroom. Green text marks the cheaper city per line.
Chattogram is cheaper on ten of twelve cost lines. The central one bedroom at 145 dollars against the Mumbai 685 dollars compounds across a 12 month lease into 6,480 dollars of preserved capital before tax. The single resident monthly all in at 545 dollars against the Mumbai 1,425 dollars produces a 10,560 dollar annual differential. Mumbai wins on the public transport monthly at 12 dollars against 18 dollars off the local train and the Mumbai Metro network density, and on the internet at 12 dollars off the Jio and Airtel competitive pricing tier.
The Mumbai premium runs on the constrained South Bombay land supply at the Nariman Point, the Worli, and the Bandra peninsula along with the western suburbs at Andheri, Powai, and Versova, with the Indian rupee at 86 to the dollar carrying an inflated central rent baseline. The Chattogram grocery basket runs at 35 percent below the Mumbai equivalent on the lower base food cost across the Bengali rice staple plus the lentil and fish protein layer. The cost of living report walks the basket math.
For the international transfer side, Wise handles BDT and INR conversion at within 1.4 percent of the mid market rate, well below the 4.5 percent that Indian and Bangladeshi retail banks apply on retail FX. The cost converter tool takes a salary in either direction and produces the purchasing power adjusted equivalent.
The 10 point safety read across the four sub axes the methodology weights equally.
Mumbai wins safety on five of five sub axes by 0.4 to 1.0 points. The 6.4 Mumbai overall sits in the South Asian upper mid quartile, supported by the Mumbai Police operational footprint at the central business district, the active CCTV network at 6,200 cameras, and the structurally low violent crime rate at 2.4 incidents per 100,000 residents. Chattogram at 5.6 sits at the lower band on the structurally larger informal settlement footprint and the limited Bangladesh Police presence outside the central commercial spine.
For the new arrival, SafetyWing covers the first six months at 48 to 65 dollars a month. The Mumbai residential pattern runs the gated tower at Worli, Lower Parel, Bandra, or Powai at 28 to 64 dollars a month for the 24 hour security service through the building society levy. The Chattogram pattern runs the gated residence at the Khulshi, Agrabad, or GEC Circle expat axis at 85 to 165 dollars a month. The safest cities ranking places Mumbai at number 162 globally and Chattogram at number 268.
Healthcare quality. Mumbai anchors at the Kokilaben Dhirubhai Ambani Hospital, the Hinduja Hospital, the Lilavati Hospital, the Breach Candy Hospital, and the Tata Memorial Hospital at 185 to 425 dollars a month for the comprehensive medical aid plan. Chattogram runs the Imperial Hospital, the Chittagong Medical College Hospital private wing, and the Max Hospital at 95 to 185 dollars a month for the equivalent plan, with medical evacuation to Mumbai, Singapore, or Bangkok covering the complex case. The quality of life ranking places Mumbai at number 242 globally and Chattogram at number 318.
Annual averages, the worst month, and the count of days in the comfort band.
Mumbai wins on four of seven climate axes. The 34 fewer rainy days a year, the 442 more sunshine hours, the lower humidity at 76 percent against the Chattogram 79 percent, and the warmer 62F winter night all favor Mumbai. The southwest monsoon runs June through September in both, with Mumbai taking 2,168 mm aggregate over the monsoon window against Chattogram at 2,484 mm. The Mumbai monsoon floods at the King Circle, the Hindmata, and the Andheri Subway are the structural seasonal risk, with the 2024 flooding at 285 incidents the highest reading on the recent record.
Air quality. Both cities sit in the PM2.5 elevated band. Mumbai averages 64 micrograms PM2.5 year round, off the diesel truck traffic on the Eastern Express Highway, the construction dust on the metro line extension corridor, and the industrial cluster at Trombay. Chattogram averages 56 micrograms PM2.5 year round, the cleaner of the two off the Bay of Bengal maritime wind cycle. The clean air ranking places Mumbai at number 312 globally and Chattogram at number 328.
Cyclone exposure. Both sit on cyclone corridors. Chattogram runs the direct Bay of Bengal cyclone exposure at the 2,485 designated shelter network. Mumbai runs the Arabian Sea cyclone exposure at lower frequency, with Cyclone Tauktae in 2021 the most recent significant landfall on the western coast. The climate match tool finds cities with similar profiles, including Kolkata, Chennai, and Colombo.
Median salaries for three mid level roles, the headline tax band, and the effective rate after standard deductions.
Mumbai pays 3.2 to 4.8 times Chattogram on private sector technology and finance roles, off the Indian capital markets depth and the multinational regional headquarters concentration at Nariman Point, Worli, and the Bandra Kurla Complex. The Mumbai senior engineering tier at 58,000 dollars sits well above the Chattogram 14,500 dollar equivalent, with HDFC Bank, ICICI Bank, Tata Consultancy Services, Reliance Industries, the global investment bank India desk at JPMorgan and Morgan Stanley, and the technology unicorn tier (Paytm, Zomato, PhonePe) anchoring the upper band.
Tax. Chattogram runs the Bangladeshi top marginal rate at 25 percent on income above 1,650,000 BDT with the effective rate at 22 percent on a 100,000 dollar gross. Mumbai runs the Indian top marginal rate at 39 percent (including the surcharge and cess) on income above 5 crore rupees, with the effective rate at 32 percent on the same 100,000 dollar gross. The tax calculator tool runs your number against either.
The major employers in Mumbai are the Reserve Bank of India, HDFC Bank, ICICI Bank, State Bank of India headquarters, the Tata Group across Tata Consultancy Services, Tata Steel, and Tata Motors, Reliance Industries, Larsen and Toubro, Hindustan Unilever, the Bombay Stock Exchange listed tier, the global investment bank India desk, the Hindi cinema cluster on the Andheri Goregaon axis, and the technology unicorn tier at Powai. The major employers in Chattogram are the Chittagong Port Authority, Western Marine Shipyard, GPH Ispat, BSRM Steels, the readymade garment cluster at the Chittagong Export Processing Zone, and the offshore oil and gas operators. The cities for finance ranking places Mumbai at number 22 globally and Chattogram at number 302.
The qualitative axes scored on the same 10 point scale the index uses elsewhere.
Mumbai wins lifestyle on all five axes by 1.6 to 3.4 points. The Mumbai nightlife at the Bandra, Worli, and Lower Parel corridor runs the deepest scene in India with the Toto's Garage, the Soho House Mumbai, the Bonobo, and the Trilogy on rotation. The food scene at 8.2 sits well above the Chattogram equivalent on the broader range of Maharashtrian, Mughlai, South Indian, Goan, Parsi, Chinese, and global fine dining layers, with the Michelin Guide India 2026 awarding three stars to Trèsind Mumbai and two stars to Indian Accent. The foodies ranking places Mumbai at number 24 globally and Chattogram at number 224.
Cultural density. Mumbai anchors the broader Hindi cinema industry, the National Centre for the Performing Arts, the Royal Opera House, the Jehangir Art Gallery, and the Bhau Daji Lad Museum. Chattogram runs the more limited cultural footprint on the World Heritage Mahasthangarh archaeological proximity and the Chittagong University cultural calendar. The Mumbai public transit at 7.2 runs the Mumbai Suburban Railway at 7.5 million daily ridership and the Mumbai Metro on three operational lines.
The boring section that decides whether the move actually happens.
Visa difficulty separates them by one point. Chattogram runs the Bangladeshi E visa at 200 dollars for the 1 year permit and the 4 to 8 week processing window. Mumbai runs the Indian Employment Visa through the Ministry of Home Affairs at 295 dollars for the 1 to 5 year permit and the 6 to 12 week processing window at the 25,000 dollar minimum annual salary threshold (the foreign worker salary floor under the 2009 rule). The 2026 visa guide covers both pathways.
The Indian e visa runs 25 dollars at 30 days for the 165 nationality eligibility list with the 2025 expansion that added the e Business and e Conference variants. Bangladesh runs 50 dollars at 30 days for the 84 nationality list. India does not yet offer a dedicated digital nomad visa though the parliamentary 2026 winter session has the proposal on the docket. The digital nomad cities ranking places Mumbai at number 142 globally and Chattogram at number 282.
Working language. Chattogram operates in Bengali at the local government and judicial tier, with English as the multinational corporate working language. Mumbai operates in Hindi, Marathi, and English at the local government and corporate tier, with English as the dominant business language across the global investment bank and the technology unicorn cluster. The best banks for expats guide walks the multi currency account math.
Education. Mumbai runs the international school stack at 18,000 to 38,000 dollars a year across the American School of Bombay, the Dhirubhai Ambani International School, the Ecole Mondiale World School, and the Bombay International School. Chattogram runs the international stack at 6,500 to 14,000 dollars a year across the Chittagong Grammar School and the South Asian International School. The international schools ranking places Mumbai at number 88 globally and Chattogram at number 318.
Move logistics. The shipping container math from Europe runs 3,200 to 5,800 dollars on a 20 foot to either; the Jawaharlal Nehru Port handles Mumbai inbound at the 32 kilometer link to central Mumbai and the Port of Chattogram handles direct urban perimeter inbound. The pet relocation timeline is 21 days for India and 12 days for Bangladesh from the rabies free origin list. The relocation checklist covers both.
For the executive at the Reserve Bank of India, HDFC Bank, ICICI Bank, the Tata Group corporate base, the global investment bank India desk at Nariman Point, the Hindi cinema cluster on the Andheri Goregaon axis, or the technology unicorn tier at Powai and the Bandra Kurla Complex, and the household weighting the salary line at 3.2 to 4.8 times the Chattogram rate, Mumbai wins. The capital markets depth and the cultural output survive the cost premium.
For the operator at the Port of Chattogram, the readymade garment factories at the Chittagong Export Processing Zone, the BSRM Steels and GPH Ispat industrial cluster, the offshore oil and gas operators on the Bay of Bengal block tier, and the household weighting the lower cost line at 10,560 dollars annually below the Mumbai equivalent, Chattogram wins. The Bay of Bengal maritime moderation holds against the Mumbai monsoon flooding.
