A free mahr calculator for Muslim couples — estimate a fair, meaningful mahr (Islamic dower) based on the husband's means, set the prompt versus deferred split, and learn how to make the mahr enforceable in U.S. court with an Islamic prenup. Published by HalalWallet.

Mahr Calculator

How much mahr should you give? There's no fixed amount in Islam — the mahr should be meaningful to the wife but not a hardship to the husband. This calculator turns the husband's means and your chosen approach into a suggested range and a prompt-vs-deferred breakdown, so you have a concrete number to discuss together. It's a starting point for the conversation, not a religious ruling.

Make this mahr enforceable

A nikah mahr is often unenforceable in U.S. court — an Islamic prenup fixes that

There is no required mahr amount in Islam — it should reflect the husband's means and be meaningful without causing hardship. This calculator suggests a moderate range from the husband's income and savings, splits it into prompt (paid at the nikah) and deferred (owed later) portions, and shows how to make the mahr enforceable in U.S. court with an Islamic prenup.

  • No fixed mahr amount exists in the Quran or Sunnah — moderation is the guidance
  • The mahr is the wife's exclusive right, to be agreed together
  • Mahr can be split into prompt (at nikah) and deferred (owed later) portions
  • A nikah mahr is often unenforceable in U.S. court — an Islamic prenup fixes that

How to use the result

Use the suggested range as a conversation anchor, not a verdict. The mahr is the wife's right, so her wishes lead. Once you've agreed an amount and a prompt/deferred split, write it down clearly — and to make it actually hold up under U.S. law, record it in an Islamic prenup. For the full background on prompt vs deferred mahr, what can serve as mahr, and what happens at divorce or death, read the complete mahr guide.
