MySQL (free) and Oracle BYOL (no additional license cost) are the same cost at RDS. Since PG is free, I'd guess the cost will be the same as MySQL.

That's what I think too, they should state MySQL/PostgreSQL or something like that in the calculator though.

PostgreSQL costs more than MySQL according to http://aws.amazon.com/rds/pricing/ .

Price difference seems huge. Looks more than Oracle? Can anyone explain why?

Either they updated the table since you posted, or you're misreading it. MySQL Large is $0.32/hr, PG Large is $0.336/hr, Oracle is $0.565/hr.

I don't know why the MySQL/PG prices are different.

My fault. I misread it. PostgreSQL has only heavy-utilization unit on reserved instance. I thought it's light utilization unit.

Heavy/Large/1yr(reserved, multiAZ)/Tokyo: PostgreSQL = $1548, Oracle = $2440

Seems reasonable price. And I don't care MySQL price because it's not an option to me.
