The e Visa fees are divided into four slabs of zero, USD25, USD80 and USD100, depending on nationality (based on reciprocity), plus a bank fee of 2.5% of the visa fee. Check out the detailed visa fee chart here.
Take note that it is FREE for countries such as Indonesia, Jamaica, Kiribati, Marshall Islands, Mauritius, Micronesia, Myanmar, Nauru, Niue Island, Palau, Papua New Guinea, Samoa, Seychelles, Solomon Islands, South Africa, Tonga, Tuvalu, Uruguay, & Vanuatu. LUCKY them!
For Filipinos like me, it costs me USD80.00 (plus a bank fee of 2.5% of the visa fee).
NOTE: Payment is non-refundable.
UPDATE: In August 2019, the Indian Government announced a 30 Day Visa during the peak season for 25 USD. Refer to related news here.
