How much you give is up to you- in theory.
ACTUAL QUOTES FROM CHC MEMBERS:
For tithe: "Follow the standard percentage"
For offering: "Give whatever extra you feel is needed."
For building fund: "If you want to worship in a nice building,
it's not free. This is separate from the tithe and offering, this
is for the new building at Toa Payoh."
Don't forget they will provide a receipt for your donations,
whether cash or cheque or Giro, management know how much you give.
Your CG leader or Zone Supervisor will actually come and talk to
you and say: "you are quite well off, can you give more?"
Yah some poor church mates do not give any money at all.
Wealthy ones on the other hand can give more than 10
percent.
Some devout christians who do not have children can donate
entire house to church too.
I heard donation to churches can be used to deduct from taxes
like donating to charity and welfare organisation.
I rather give church than government in my opinion.
Our government is very rich already.
Look at how much ERP earn them a day. Do not forget about COE
prices.
