Here’s my 5D4N Singapore (with 1 day Malaysia) Itinerary. I hope this helps!
Singaporean Dollar: SGD384.30 = PHP12,835.62 (August Conversion Rate – SGD1:PHP33.40)
Total Expenses in Peso (excluding pasalubong/souvenirs): =PHP15,560.62
*Please note that we visited 2 Theme Parks (which are expensive) that’s why the budget was a little higher than the usual. 😀
