You can always ask an elder or deacon or the pastor. Our church currently is doing a capital campaign to be able to redo the parking lot and parsonage. We have a goal (plus our regular church expenses and outreach) that we would like to reach. Our church broke down how much each person could give on average to reach our goal by a certian timeline. It is not required to give accoording to the goal but lets me have a ball park then we can go thru our finances and decide what works for us. Hope that helps. For us it does work out to be a bit lower than 10%. You can change your mind again next week as you decide what works for you.
