Compulsory government charges only. Service fees and anything optional are excluded, which is what makes the figure comparable.
Yellow fever certificate
Arriving from Bangladesh, no yellow fever certificate is required: WHO does not list Bangladesh as a transmission risk. It can still be demanded if you have been in a risk country shortly before arriving.
Driving on a Bangladesh license
Bangladesh is party to the 1949 Geneva Convention and Maldives to the 1968 Vienna Convention. They share none, so no treaty obliges Maldives to recognize an International Driving Permit issued in Bangladesh.
Whether a permit is required alongside your national license is set by national road law, which we have not checked for this pair.
Passport validity — Maldives Immigration says you need a passport or travel document with a machine-readable zone and at least 1 month's validity; the UK Foreign Office says your passport must have an expiry date at least one month after the date you arrive. Canada's travel advice says a Canadian passport must be valid for at least 6 months from the date of entry.
Imuga Traveller Declaration — Maldives Immigration says all travellers must submit the Traveller Declaration within 96 hours before their flight time for arrival, free of charge; the IMUGA home page lists it as a mandatory declaration within 96 hours of arrival or departure. It strongly advises using the IMUGA portal (imuga.immigration.gov.mv) and avoiding other websites that may charge a fee.
No official source states a rule on: travel insurance.
