Most poskim hold that maaser is calculated on net income after taxes and legitimate business expenses. However, some follow the more stringent view of gross income. Consult your Rav for personal guidance.

Maaser Percentage

Choose your giving level

Standard maaser is 10%, but some give more based on their financial situation.

The 20% Limit

Chazal teach that one should not give more than a fifth (chomesh, 20%) of their wealth to tzedakah, lest they themselves become needy. This limit doesn't apply if you're very wealthy.

How to use this tool

Getting started

  • Choose your baseline: Most people calculate maaser on net income after taxes, but some use gross. Select what works for your situation.
  • Deduct business costs: If you're self-employed, you can deduct legitimate business expenses before calculating maaser.
  • Track over time: Set the tracking period (usually 12 months) to see your annual obligation and progress.
  • Stay current: Update the "amount given" field regularly to monitor your remaining obligation.

Common questions

Maaser fundamentals

  • Principal gifts: Money received as a gift (wedding, inheritance) is subject to maaser on the principal amount.
  • Investment gains: Profits from investments and capital gains are subject to maaser.
  • Maaser funds: You can only use maaser money for true tzedakah, not for mitzvos like Shabbos candles or synagogue dues.
  • Family support: Supporting adult children who are learning or in need may be considered tzedakah if they're not your obligation.

Best practices

Practical tips

  • Automate it: Set up automatic transfers to a tzedakah account when you receive income.
  • Keep records: Maintain a log of all maaser calculations and payments for tax purposes and clarity.
  • Consult your Rav: Everyone's situation is unique. Ask shailos about your specific circumstances.
  • Be consistent: It's better to commit to 10% consistently than to aim for 20% and fall short.
