How to Calculate Zakat in the UK: 2026 Step-by-Step

Calculating Zakat in the UK comes down to four numbers and one date. The four numbers are: what you own that's zakatable, what you can deduct, the current nisab in pounds, and 2.5%. The date is your Zakat anniversary, the day each year your wealth has been above nisab for a full lunar year. Get those right and the rest is arithmetic.

If you're new to this, don't worry. We'll walk through it.

Let's start.

Step 1: Pick your Zakat anniversary

Your Zakat anniversary is the date your zakatable wealth first crossed the nisab threshold. From that point, you owe 2.5% on what you own at the same date next lunar year, not next solar year. The lunar year is 354 days, 11 days shorter than the Gregorian one. If you're tracking by Gregorian dates you'll under-pay over time, so it matters.

Most UK Muslims either pick a date in Ramadan (the rewards are multiplied) or pick the day they first received a meaningful sum (a salary milestone, an inheritance, the day they paid off a credit card). Pick one, write it down, and stick with it. Once it's set, every year on that lunar date you'll do the same calculation: add what's zakatable, subtract what's deductible, compare to nisab, multiply by 2.5%, give within a reasonable window. The discipline of having a fixed date matters because Zakat isn't a flexible obligation. The lunar calendar moves the date forward 11 days each Gregorian year, and over a decade that compounds into months of difference, which is why anchoring to a lunar date keeps you honest.

Step 2: Add up what you own

On your Zakat anniversary, list every zakatable asset at its current market value. Not the price you paid. The current value. For UK Muslims in 2026, the common categories are below.

Step 3: Subtract what you owe

You can deduct genuine, immediate debts from your zakatable total. The Hanafi school is the most permissive here; the Shafi'i school is stricter and excludes long-term debts entirely. The middle position, which many UK fatwa councils now follow, is to deduct only the next 12 months of any long-term debt.

What counts as deductible

• Outstanding bills due now (electricity, council tax arrears)
• Credit card balances you intend to clear
• Personal loans, the next 12 months of repayments
• Mortgage: only the next 12 months of capital repayments (interest portion isn't yours either way)
• Money you owe a family member or friend
• Tax owed to HMRC for the current year

What does not count

• Future bills you haven't received yet
• The full mortgage capital: most UK scholars only allow 12 months at a time
• Speculative or contingent debts

Step 4: Compare against nisab

Subtract your deductible debts from your zakatable assets. This gives you your net zakatable wealth. If that figure is above the nisab threshold, you owe Zakat on the full amount, not just the bit above nisab. If it's below, you owe nothing this year, and your anniversary clock resets.

There are two nisab values to choose from. Gold nisab is 87.48 grams of gold (around £5,740 in early 2026). Silver nisab is 612.36 grams of silver (around £550 in early 2026). The numbers shift daily with spot prices, which is why we keep a live figure on the current nisab threshold page. Use silver if you want to maximise the wealth captured for charity. Most UK fatwa councils, including the National Zakat Foundation, recommend silver for that reason.

Step 5: Multiply by 2.5%

If your net zakatable wealth is above nisab, multiply it by 0.025. That's your Zakat. The rate hasn't changed in 1,400 years.

A worked example

Aisha is a 32-year-old project manager in Manchester. Her Zakat anniversary is 15 Ramadan. On that date in 2026 she has: £4,200 in her current account, £8,500 in a Cash ISA, £3,100 in a Stocks & Shares ISA (S&P 500 tracker), £1,800 in Bitcoin she bought as a long-term hold, and 24 grams of gold jewellery she wears regularly.

She owes £1,200 on a personal loan and her next 12 months of mortgage capital repayments come to £4,800. She follows the Shafi'i school, so her gold jewellery in regular personal use is exempt.

£9,275 is well above the silver nisab of around £550. Aisha owes 2.5% × £9,275 = £231.88. She rounds up to £232 and gives it through verified Zakat-eligible campaigns on AmalQ before her next anniversary.

Step 6: Pay it where it counts

Zakat isn't optional charity. It's one of the five pillars and the Quran specifies eight categories of recipient in Al-Tawbah 9:60: the poor, the needy, those who collect and distribute Zakat, those whose hearts are to be reconciled, captives seeking freedom, those in debt, in the cause of Allah, and the wayfarer. A platform that calls itself 'Zakat-eligible' should be able to tell you which of these categories your money supports, and how it traces delivery.

At AmalQ we tag every campaign by Islamic category (Zakat, Sadaqah, Waqf, Fitrah, Qurbani) and route Zakat donations only to causes scholars have verified meet at least one of the eight categories. The scholar review process is documented publicly so donors can see exactly how a campaign earns the Zakat tag.

Common mistakes UK donors make

1. Using the Gregorian year instead of lunar. 11 missed days a year compounds; over a decade you under-pay by roughly four months of wealth growth.
2. Forgetting Cash ISA balances. The 'wrapper' is a tax label; Islamically it's still your savings.
3. Treating the home as zakatable. Your primary residence is exempt no matter how much it has appreciated.
4. Deducting the entire mortgage. Most UK scholars cap mortgage deduction at 12 months of capital repayments, not the full outstanding balance.
5. Skipping the Stocks & Shares ISA because 'it's locked away'. An ISA isn't locked. You can withdraw any time. It counts.
6. Paying late. Zakat is due on your anniversary, not at year-end. Missed years still count and need to be paid.

When AmalQ can save you the maths

If the worked example above looked like a lot, the AmalQ Zakat calculator handles every step we've described, with the live nisab pulled from spot-price feeds. You enter the same numbers, pick your school of thought for the disputed categories, and the calculator returns the figure plus a list of verified Zakat-eligible campaigns where you can give immediately.

We've seen first-time users finish in under five minutes once they have their bank balances open. It's not magic. It's just the same arithmetic, with the inputs structured for you.

Zakat is the right of the poor in the wealth of the rich. The arithmetic is simple. The discipline of doing it every year is what counts.

Frequently asked questions

When is Zakat due in the UK?

Zakat is due on your personal Zakat anniversary, one full lunar year (354 days) after your wealth first crossed the nisab threshold. Many UK Muslims choose a date in Ramadan because the rewards are multiplied, but any consistent date works. The key is consistency: pick a date and use it every year.

Should I use the gold or silver nisab?

Most UK fatwa councils, including the National Zakat Foundation, recommend the silver nisab because it's lower (around £550 in 2026 versus around £5,740 for gold) and therefore captures more wealth for distribution to those in need. The Hanafi school traditionally favoured silver for this reason. Both are valid; silver is simply more cautious.

Do I pay Zakat on my house or car?

No. Personal-use assets (your primary residence, your car, household furniture, clothing, and tools of your trade) are exempt from Zakat. The exemption applies even if the home has appreciated significantly. Property held as a buy-to-let investment is treated differently: the rental income counts as cash, but the property itself usually does not.

Can I deduct my mortgage from my Zakatable wealth?

You can deduct the next 12 months of capital repayments, not the full outstanding mortgage balance. This is the position taken by most UK scholars and matches AAOIFI guidance. Deducting the entire mortgage would wipe out almost everyone's Zakat liability and isn't supported by classical fiqh.

What if my Zakatable wealth is below nisab?

You don't owe Zakat this year. Your anniversary clock resets; when your wealth next crosses nisab, that becomes your new starting date. You can still give Sadaqah (voluntary charity) freely, which is highly encouraged but not obligatory.

Do I pay Zakat on my workplace pension?

Most UK scholars say yes for defined-contribution pensions and SIPPs because the assets are notionally yours and you can access them at retirement. Defined-benefit (final salary) schemes are usually treated as not Zakatable until you start drawing them. Our guide on Zakat on pensions, shares and crypto walks through the calculation methods used by the Islamic Finance Guru and the National Zakat Foundation.

How do I calculate Zakat on Bitcoin or other crypto?

Take the GBP market value of your crypto holdings on your Zakat anniversary date, not the price you bought at. Add it to your other zakatable assets and apply the 2.5% rate. The Fatwa Centre of America and several UK scholars confirm crypto held as an investment is treated like any other tradeable asset.

Can I pay my Zakat in instalments through the year?

Yes. Many UK Muslims pre-pay Zakat in monthly instalments and reconcile on their anniversary. If you've over-paid, the surplus counts as Sadaqah; if you've under-paid, you settle the balance on your anniversary date. Some donors also pay early to support a specific cause without waiting for their anniversary.
