Loans and debts are one of the most common areas of confusion when calculating Zakat. This 2026 UK guide explains exactly which debts reduce your Zakatable wealth and which don’t — using the live UK Nisab figures: Gold £8,436 · Silver £987 (updated 2 June 2026).
For the full interactive tool, use our Zakat Calculator 2026. This page focuses specifically on how loans affect your calculation.
The Core Principle
Zakat is paid at 2.5% on your net Zakatable wealth on your Hawl (lunar-year) anniversary. To find your net figure, subtract qualifying debts from your qualifying assets. If what remains is above the Nisab, Zakat is due on the whole net amount.
Short-Term Debts (Fully Deductible)
These are debts that are due now or within the next twelve months — they reduce your Zakatable wealth pound-for-pound:
- Unpaid bills — utilities, council tax, rent already owed.
- Credit card balance outstanding on your Zakat date.
- Overdrafts currently in use.
- Personal loans from family or friends that are recallable on demand.
- Buy Now Pay Later balances (Klarna, Clearpay) and the next twelve months of car-finance instalments.
- Business trade payables due within the year.
Long-Term Debts (Partially Deductible)
For debts that stretch beyond twelve months — mortgages, long personal loans, multi-year car finance — the UK scholarly consensus is to deduct only the next twelve months of principal/capital repayments, not the full outstanding balance. The interest (Riba) portion is never deducted.
- Mortgages — see our dedicated Zakat & mortgage guide.
- Islamic home finance (Ijara, Murabaha, Diminishing Musharakah) — same twelve-month rule.
- Multi-year car finance — deduct only the next twelve months’ capital portion.
Debts That Are Not Deductible
- UK Student Loans Company (SLC) loans — contingent on future income, written off after 25–40 years. See our student loans guide.
- Future or hypothetical liabilities — e.g. next year’s school fees you have not yet committed to.
- The interest (Riba) portion of any loan.
Money Owed To You
Loans you have given to others are an asset and are added to your Zakatable wealth, provided you reasonably expect repayment. If the debt is doubtful (e.g. the borrower is insolvent), most scholars allow you to wait and pay Zakat only when (and if) it is repaid — then for one year only, regardless of how long it was outstanding.
Worked Example
Savings £8,000 + gold worth £2,000 + money lent to a friend £1,000 = £11,000 assets. Credit card £500 + unpaid utility bill £150 + next 12 months of car-finance capital £2,400 = £3,050 deductible debts. Net Zakatable wealth = £7,950. That is above the Silver Nisab (£987), so Zakat owed = £7,950 × 2.5% = £198.75.
Frequently Asked Questions
Can I deduct the full balance of a long-term loan?
No. Only the next twelve months of capital (non-interest) repayments may be deducted from your Zakatable wealth.
Is my credit card balance fully deductible?
Yes — the balance you owe on your Zakat date is a short-term debt and reduces your Zakatable wealth pound-for-pound. The interest charged is never deducted.
Do I add money I have lent to others to my Zakatable wealth?
Yes, if you reasonably expect repayment. For doubtful debts you may delay Zakat until repayment, then pay for one year only.
What about my UK student loan?
SLC loans are treated as contingent liabilities. The outstanding balance is not deducted — only the next twelve months of PAYE repayments if you are earning above your plan threshold. See our student loans guide.
