A Wedding in the Philippines depends really on how grand and luxurious the parties to the wedding want the occasion to be, for example, if you want a lavish church wedding and the pews decked out in expensive floral arrangements, and the brides outfit is lined with diamonds or something like that, then of course you will spend more.
Everyone cuts their cloth according to their personal finances, like Aromulus, my wedding cost around £1500.00 but my best friends cost £5000.00, they wanted a sosyal wedding with lots of money for the reception, but it depends on how many guests will attend, if there is 100, some of the hotels do an excellent package up to a 100.00 for about P40,000 to P50,000 but then in Manila maybe the costs are higher than the provinces, which have been my experiences.
Everyone's experience will be different, so its best to make a wedding plan, see what sort of things you would want, and then cost it out to the last peso and see how your budget is.
