Tithe Calculator

This calculator figures out how much to give based on your income, following the traditional 10% tithe rate widely practiced across many Christian traditions, alongside any additional offering percentage you choose to give above and beyond the tithe. It multiplies Gross Income Per Pay Period by the Tithe Percentage to get Tithe Per Paycheck, then separately annualizes your income using Pay Periods Per Year to compute Annual Tithe and Total Annual Giving. Gross Income and Tithe Percentage are mathematically tied in their effect on Tithe Per Paycheck -- since it's a straight product of the two, both move the result by the same magnitude, in the same direction, which is expected since the per-paycheck tithe is simply that percentage applied to that period's income.

Pay Periods Per Year, notably, has no effect on Tithe Per Paycheck at all -- it only scales the annualized figures, since your tithe amount for a single paycheck depends only on that paycheck's income and the percentage you've set, not on how many paychecks you receive in a year. This calculator does not take a position on whether tithing should be calculated from gross or net income after taxes -- that distinction varies by personal conviction and church teaching -- and it does not account for irregular or self-employment income, where pay periods aren't evenly spaced.
