Cost of Living/Purchasing Power
According to the indicated sites, you need the equivalent of around 115,893.06 ₱/ 2000 Euros in Manila to maintain the same standard of life that you can have with 7,000 Singapore Dollar in Singapore (assuming you rent anhd apartment in both cities).
Something similar applies also to locations within Metro Manila herself: In Paranaque, GESM's location, cost of living is lower than in Makati or Ayala Alabang, epecially rent. That is why some teachers prefer living in our barangay, or neigbouring barangays like Better Living, Moonwalk, Don Bosco or Merville. Of course, we have staff also living in Makati and Alabang, this is up to the individual teacher to decide and depends on their mix of preferences.
