Sharia-Compliant

Halal Mortgage Calculator

Calculate Sharia-compliant home finance across all three main structures — Musharakah, Murabaha, and Ijara — without interest (Riba).

Diminishing Musharakah — Co-ownership

You and the bank jointly own the property. Each month you pay rent on the bank's share, plus a fixed buyout instalment. As your ownership grows, the rental portion decreases. This is the most common halal mortgage structure in the UK and UAE.

The Principle: Financing Without Riba

In Islamic finance, a "mortgage" is not a loan. It is a home purchase plan. In a conventional mortgage, the bank lends you money and charges interest (riba) for the use of that capital. In a halal mortgage, the bank provides an asset-based transaction — a sale, a lease, or a partnership.

Each structure has a specific contractual basis verified by a Sharia Supervisory Board. While the monthly payments may look similar to a conventional loan, the legal nature of the transaction is fundamentally different. You are not a debtor; you are either a tenant, a partner, or a purchaser of a marked-up asset.

The Three Pillars of Home Finance

Understanding the legal chemistry behind your home ownership journey.

Diminishing Musharakah

المشاركة المتناقصة

Most common in UK & UAE

You and the bank co-own the property from the date of purchase. Each month you make two payments: rent on the bank's share of the property, and a fixed buyout instalment that transfers a portion of the bank's ownership to you. As your equity stake grows, the rent portion decreases because you're renting a smaller share. By the end of the term, you own 100% of the property outright.

# Process Chain

  • 1.Bank and customer enter a Shirkat ul Milk (joint ownership) agreement
  • 2.Customer pays monthly rent (Ijara) on the bank's share
  • 3.Customer also pays a fixed instalment to buy out the bank's units of ownership
  • 4.As ownership units transfer, the rental base shrinks each year
  • 5.Full ownership transfers when all units are purchased

Ideal Use Case

First-time buyers, residential purchases, remortgages

Sharia Authority

Approved under AAOIFI Sharia Standard No. 12 (Sharika/Musharakah)

Murabaha

المرابحة

Fixed profit — no rate changes

The bank purchases the property outright in its own name and then sells it to you at a pre-agreed higher price. The difference between the two prices is the bank's profit, and it is fixed at the point of signing — it cannot increase, decrease, or compound over time. You pay the total sale price in monthly instalments over the agreed term. Because this is a sale transaction and not a loan, no interest (riba) is involved.

# Process Chain

  • 1.Bank buys the property from the seller in a cash transaction
  • 2.Bank discloses its cost price to the customer (transparency is a Murabaha requirement)
  • 3.Customer agrees to buy the property from the bank at cost + agreed profit margin
  • 4.Total sale price is divided into equal monthly instalments
  • 5.Once the final instalment is paid, legal title transfers to the customer

Ideal Use Case

New builds, shorter terms (5–15 years), buyers who want payment certainty

Sharia Authority

Approved under AAOIFI Sharia Standard No. 8 (Murabaha)

Ijara wa Iqtina

الإجارة والاقتناء

Popular in GCC & buy-to-let

The bank purchases and retains ownership of the property throughout the term. You lease the property from the bank and pay monthly rent. Separately, you make capital contributions that accumulate towards the eventual purchase. At the end of the term, ownership transfers to you — either automatically or for a nominal sum — under a separate sale or gift agreement (hiba). This structure is particularly common in the Gulf Cooperation Council (GCC) and for buy-to-let investment finance.

# Process Chain

  • 1.Bank purchases property and becomes full legal owner
  • 2.Customer and bank sign a forward purchase undertaking (wa'd)
  • 3.Customer pays monthly rent (Ujra) for use of the property
  • 4.Monthly capital contributions build towards ownership transfer
  • 5.Ownership transfers at term end via gift (hiba) or nominal sale

Ideal Use Case

Buy-to-let, commercial property, GCC residents, portfolio landlords

Market Insight: UK Providers

The UK is home to one of the most mature Islamic finance markets globally. Government reforms in the 2000s removed double-transaction taxes, allowing halal mortgages to compete on a level playing field.

Critical FAQ

Addressing the most common points of confusion.

Is a halal mortgage really free from interest?

Yes — all three structures avoid riba (interest) by design. In Murabaha, the bank earns a profit on a sale transaction, not interest on a loan. In Musharakah and Ijara, the bank earns rent as a property owner, not interest as a lender. These are fundamentally different contractual relationships, even though the monthly payment amounts can look similar to a conventional mortgage.

Why is the profit rate similar to conventional mortgage rates?

Islamic finance providers operate in the same competitive market as conventional lenders and face similar funding costs. The profit/rental rate is benchmarked to market rates (often SONIA or the Bank of England base rate in the UK) to remain competitive. The rate being similar to interest does not make it interest — the underlying contractual structure determines Sharia compliance, not the numeric value of the rate.

Which halal mortgage structure is cheapest?

For the same property value, deposit, term, and rate, Diminishing Musharakah and Ijara produce identical total costs because they use the same amortising payment formula. Murabaha is calculated differently — the profit is a flat markup rather than a declining balance calculation — which means the total cost can differ, especially on longer terms. Use the calculator above to compare all three with your actual numbers.

Can I get a halal mortgage in the UAE or Saudi Arabia?

Yes. Islamic home finance is the dominant product in the GCC. In the UAE, providers include Emirates Islamic, Mashreq Al Islami, Amlak, and DIB. In Saudi Arabia, Al Rajhi Bank and Saudi National Bank (SNB) both offer Sharia-compliant home finance products. The structures used are most commonly Diminishing Musharakah and Ijara, aligned with local Sharia supervisory board approvals.

What deposit do I need for a halal mortgage?

Requirements vary by lender and product. In the UK, most Islamic mortgage providers require a minimum 10–20% deposit for residential purchases (80–90% LTV). For buy-to-let, a 25–40% deposit is typically required. A larger deposit (lower LTV) generally earns a better profit rate, exactly as with conventional products.
