Zakat Calculator

Our Zakat Calculator helps you estimate how much Zakat may be due on your total zakatable wealth. You can enter cash, bank savings, gold, silver, jewellery, investments, business stock, trade receivables, and personal debts — and the calculator will show your net zakatable wealth, compare it to the Nisab threshold, and give you an estimated Zakat amount at the standard 2.5% rate.

The tool supports manual Nisab entry, which means it works regardless of your currency — making it suitable for Muslims in the UK, Pakistan, India, UAE, Saudi Arabia, Bangladesh, and elsewhere.

Understanding Zakat: The Basics

Zakat is the third pillar of Islam and one of the most significant acts of worship in the faith. It is a mandatory annual payment — typically 2.5% of eligible wealth — made by Muslims whose total zakatable assets exceed the Nisab threshold and who have held that wealth for a full Islamic lunar year (known as the Hawl).

Zakat is not a voluntary charity. It is an obligation (fard) on every Muslim who meets the qualifying conditions. Its purpose is to purify wealth, redistribute resources within the Muslim community, and support those in need — including the poor, the indebted, travellers in hardship, and those working in the service of Islam.

What Is Nisab?

Nisab is the minimum threshold of wealth a Muslim must possess before Zakat becomes obligatory. It is calculated based on the current market value of either:

  • Gold Nisab: the value of 87.48 grams of gold
  • Silver Nisab: the value of 612.36 grams of silver

Most contemporary scholars recommend using the silver Nisab because it is lower and therefore includes more Muslims in the obligation, maximising the social benefit of Zakat. However, opinions differ between schools of thought, and you should follow the guidance of your own scholar or mosque.

Because gold and silver prices fluctuate daily, the Nisab value in pounds, rupees, or dirhams changes constantly. Our Zakat Calculator allows you to manually enter the current Nisab value in your currency using a trusted source such as your local mosque or a reputable Islamic finance organisation.

What Wealth Is Zakatable?

Not all wealth is subject to Zakat. The following categories of assets are generally considered zakatable by the majority of scholars:

  • Cash in hand — physical money you hold
  • Bank balances — current accounts, savings accounts, ISAs
  • Gold and silver — jewellery, coins, bullion, and any gold/silver held as an investment
  • Business stock and trade goods — inventory held for sale
  • Investments — shares, unit trusts, and similar assets (based on their market value)
  • Money owed to you — debts or receivables you expect to recover

The following are generally not zakatable:

  • Your primary home (the property you live in)
  • Personal vehicles used for daily use
  • Household furniture and personal belongings
  • Tools used in your trade or profession

How Is Zakat Calculated?

The standard Zakat calculation follows these steps:

  1. Add up all your zakatable assets (cash, savings, gold, silver, investments, receivables, business stock)
  2. Subtract any short-term liabilities you owe and are due within the next lunar year (e.g. outstanding bills, immediate debts)
  3. If the resulting net figure equals or exceeds the Nisab, Zakat is due
  4. Zakat payable = Net zakatable wealth × 2.5%

Example: If your total zakatable wealth is £15,000, the Nisab is £450, and you have £500 in short-term debts:
Net zakatable wealth = £15,000 − £500 = £14,500
£14,500 > £450 (Nisab), so Zakat is due
Zakat payable = £14,500 × 2.5% = £362.50

Zakat on Gold and Jewellery in the UK

One of the most frequently asked questions among UK Muslims is whether Zakat is due on gold jewellery worn regularly — such as wedding rings and bangles. This is an area where scholars differ:

  • Hanafi position: Zakat is due on all gold and silver, including jewellery worn regularly, once it exceeds the Nisab and a lunar year has passed.
  • Shafi’i and Maliki position: Zakat is generally not due on gold jewellery worn for personal use, only on gold held as an investment or stored surplus.

Most UK Islamic charities and scholars follow or lean toward the Hanafi position when providing Zakat guidance. If you are unsure, consult your local imam or a reputable Islamic finance body.

Frequently Asked Questions About Zakat

When should I pay Zakat?

Zakat becomes due once you have held wealth above the Nisab threshold for a full Islamic lunar year (Hawl). Many Muslims choose to pay Zakat during Ramadan because the reward for acts of worship is multiplied during this month, but you can pay at any point once the Hawl is complete.

Who is eligible to receive Zakat?

The Quran (Surah At-Tawbah, 9:60) specifies eight categories of recipients: the poor (fuqara), the needy (masakeen), those who administer Zakat, those whose hearts are to be reconciled, those in bondage, those in debt, those in the path of Allah, and travellers in need. In a UK context, this typically includes Islamic charities distributing to those in poverty, locally and globally.

Can I pay Zakat to family members?

You cannot pay Zakat to your direct dependants — such as your spouse, children, or parents whom you are obligated to support. However, Zakat can be given to other relatives who qualify, such as siblings, cousins, or extended family members in genuine need.

Is Zakat due on pension funds?

There is scholarly debate on pension funds, particularly workplace pensions where the money is not freely accessible. Many scholars hold that Zakat is due on accessible pension funds (e.g. SIPPs where you are over 55 and can withdraw) based on current value, but not on inaccessible workplace pension pots. Consult a scholar familiar with UK pension law for specific guidance on your situation.

What is the difference between Zakat and Sadaqah?

Zakat is obligatory (fard) and has specific rules about who must pay, how much, and to whom it can be given. Sadaqah is voluntary charity with no minimum amount and no restriction on recipients. Both are encouraged in Islam, but Zakat is a pillar of the faith while Sadaqah is an act of generosity and worship.

Does the Zakat Calculator use live gold prices?

No. Because gold and silver prices change daily, our calculator asks you to enter the Nisab value manually using a trusted source. We recommend checking with your local mosque, a UK Islamic charity such as National Zakat Foundation (NZF), or a reputable Islamic finance site for the current Nisab in pounds.
