If you'd like some assistance in calculating proportional giving, here are two valuable tools. Either or both may be helpful in considering the financial commitment you believe is appropriate.
The first calculates percentages of your total income, making it easy to figure how much to contribute on a regular basis
The second makes it possible to determine what proportion/percentage of total income you are currently contributing through the church.
