Faith-Based Stewardship & Charitable Tax Metrology

Tithing models translate scripture and financial income into recurring giving schedules:

• **

• Tithing Calculation Formulas**:

Annual Tithe = Income Amount × ( Tithe \%100 )

Monthly Tithe = Annual Tithe12, Bi-Weekly Tithe = Annual Tithe26

Weekly Tithe = Annual Tithe52

• **

• Gross vs Net Tithing Debate**:

• Gross Income ('First Fruits'): Tithing on total earnings before tax/payroll deductions, reflecting Proverbs 3:

9.

• Net Take-Home: Tithing on actual disposable income received after taxes.

• **

• Standard Giving Benchmarks (10% Tithe)**:

• 45,000 Gross: 4,500 / yr

• 55,000 Net: 5,500 / yr

• 75,000 Gross: 7,500 / yr

• 100,000 Gross (12%): 12,000 / yr

Understanding Your Result

This calculation gives a precise result based on the inputs you provided. For practical decisions, consider whether the result changes meaningfully with slight variations in your inputs — if a 5–10% change in input causes a significant output change, gather more precise input data before deciding. Use this tool to quickly compare multiple scenarios side by side.
