Ministry Time Calculator

4.33 is the average number of weeks in a month (52 weeks divided by 12 months), so multiplying your weekly total by 4.33 gives a more accurate monthly estimate than simply multiplying by 4, which would understate most months. The annual figure uses a straight multiplication by 52 weeks instead, since a year always contains 52 full weeks (plus a day or two, which the calculator doesn't separately account for).

It assumes roughly 16 waking hours per day across 7 days a week, which multiplies out to 112 waking hours in a week. Your total weekly ministry hours divided by that 112 gives a rough percentage of your conscious time spent on ministry — it's a fixed assumption baked into the formula, not adjusted for your actual sleep schedule or work hours.

No — all six categories (worship, small group, volunteering, outreach, devotion, admin) are summed together regardless of whether you're a paid staff member or a volunteer. If you're on ministry staff, some of the hours you enter are already your job, so you may want to interpret the total and the '% of waking hours' figure differently than a volunteer would.

Each category's percentage is simply that category's hours divided by your total weekly hours across all six categories, multiplied by 100. Because the six percentages are derived from the same total, they always sum to 100%, which makes it easy to compare, say, your admin percentage directly against your personal devotion percentage.
