Look at your paycheck. The amount you receive after taxes is NET income. Multiply that amount by 26 if you get 26 pays per year. If you are paid twice a month, multiply by 24 or by 12 if you are paid only once a month. This is your annual net income.
Now multiply your annual net income by 10%. This amount is a tithe. Divide by 52 weeks a year. This is what should be contributed to your religious organization each week. I doubt that anyone attends services every single week of the year. I sometimes have to double up if I miss a Sunday here and there. The goal is to have that whole tithe paid in by the end of the year.
You might be thinking ...wow! I can't afford to give up that much of my yearly income. This is where percentage giving comes in. Start by multiplying your net income by 1%. Compare that to what you gave to the church last year. Is this number less than what you gave? If it is less, then is it possible to make a commitment to give at least 1% in the next year?
If you gave more than 1%, then keep multiplying your net income by increasing percentages until you get close to what you actually gave. This calculation will tell you where you are on the path toward tithing.
The point is this...figure out where you are and make a commitment to increase your giving by small percentages each year until you reach 10%.
I have often thought that finance committees should host a "Calculator Sunday", where parishioners would be given an inexpensive calculator and guided through the math right during the worship service. Gimmicky...sure it is, but I think it would drive the point home that a lot of people give less than 1% of their income to the church. My hunch is that, at the very least, this exercise would turn out to be thought provoking and might even result in increased giving.
I don't think the average person gives much thought to the cost of operating a church. For many, the only contact they have with the church is attending worship for one hour a week. We have become consumers and have the expectation that the church will provide inspiration and support at little or no cost or commitment from us.
Most of us have to live on budgets at home. Any organization we work for has a budget. In most cases, funds are not unlimited. Some churches have endowments that yield income to a certain degree, but the vast majority of religious organizations depend on the contributions of the members. Some denominations exert more pressure than others to contribute, but most are at the whim of the congregation. We want to be "fed" but are unwilling to contribute to the food budget.
Take stock of your giving by going through this simple exercise. Then ask yourself..."Does my level of giving reflect what I a receiving?"
