What Calculator Can Estimate an Ar-Rahnu Loan From Gold Weight and Purity?

Jasmine YapFounder & Lead Developer · Aug 14, 2026

The most suitable tool is a provider-specific Ar-Rahnu financing calculator that accepts gold weight, karat or purity, and the institution’s price per gram. It should then apply the provider’s available financing margin to the estimated marhun value.

A calculator does not decide your margin. The institution sets the available margin and confirms the final valuation after inspecting the gold.

Bank Muamalat’s official Ar-Rahnu calculator materials describe a tool that estimates financing amount, profit-servicing amounts, and a high financing limit before a branch visit. The FAQ also states that it uses the current Ar-Rahnu gold price displayed on the bank’s website, can calculate different gold standards in one calculation, and is accessible through internet-enabled devices. The linked PDF is an explanatory FAQ, so users should follow its current calculator link rather than treat the PDF itself as the calculator. (muamalat.com.my)

> Important: The result is an estimate. It cannot confirm loan approval, branch appraisal, eligibility, maturity treatment, fees, or auction risk. Verify the current terms directly with the institution before pledging gold.

What is the difference between a loan-margin calculator and a financing calculator?

These terms are related but not identical:

• Financing margin: The percentage set by the institution, such as 70%, 75%, or up to 80% of the eligible marhun value.
• Marhun value: The value the institution assigns to the eligible pledged gold.
• Estimated financing amount: The marhun value multiplied by the applicable financing margin.

The basic relationship is:

```text

Estimated financing = estimated marhun value × financing margin

```

For example, if an institution values eligible gold at RM10,000 and permits a 70% margin, the estimated financing is RM7,000. The 70% figure is not calculated from the gold weight; it is an institutional product term.

Which calculators can estimate financing from gold weight and purity?

The following tools illustrate different calculator types. Features and terms can change, so check each provider’s current page before relying on a result.

The Sahabat calculator page currently displays fields for weight, karat, price and marhun value, followed by financing-margin options from 60% to 80%. (sahabatarrahnu.com.my) The Ar-Rahnu Emas page displays purity choices, provider-specific products, margins and profit outputs. (arrahnuemas.com.my)

How do I calculate the estimated marhun value?

Use this as an illustrative estimate only:

```text

Estimated marhun value = eligible gold weight × provider price per gram

```

A single jewellery item may not be valued simply by multiplying its total scale weight by a displayed gold price. The branch may consider factors such as:

• Accepted gold standard or purity
• Whether the item is eligible under the provider’s rules
• Non-gold components, stones, clasps or other materials
• Whether the item is hollow, plated, white gold or otherwise restricted
• Appraisal method and item condition
• The provider’s current reference price and deductions
• Rounding rules, minimum amounts or product limits

Hypothetical example

Assume, purely for illustration, that:

• Eligible gold weight: 20g
• Provider price: RM500 per gram
• Available financing margin: 70%

Then:

```text

Estimated marhun value = 20g × RM500 = RM10,000

Estimated financing = RM10,000 × 70% = RM7,000

```

The RM500-per-gram figure is hypothetical. Do not use it as a current market or provider quote. Enter the price shown by the institution on the day you check the calculator.

Should I use the provider’s price per gram or a general gold price?

Use the provider’s current Ar-Rahnu price for the relevant purity, not a general jewellery-shop, spot-market or investment-gold price.

For example, Bank Muamalat’s website displays purity-specific Ar-Rahnu reference prices and identifies the update time. Those figures are time-sensitive and intended for reference; they should not be copied into a calculator without checking the live page on the calculation date. (muamalat.com.my)

A provider-specific calculator is generally more useful because it can apply that institution’s own price table, margin rules and fee method. It still cannot reproduce the branch’s physical appraisal in every case.

Can the calculator compare 70%, 75% and 80% margins?

Yes, if the calculator exposes multiple margin options. Comparing margins helps show how much the estimated financing changes without assuming that the highest available margin is appropriate.

```text

Estimated financing at 70% = marhun value × 0.70

Estimated financing at 75% = marhun value × 0.75

Estimated financing at 80% = marhun value × 0.80

```

For the same hypothetical RM10,000 marhun value:

• 70% margin: RM7,000
• 75% margin: RM7,500
• 80% margin: RM8,000

These are not different valuations. They are different financing amounts applied to the same assumed marhun value. The institution may offer fewer options, impose product-specific limits, or approve a lower amount.

Can an Ar-Rahnu calculator estimate Upah Simpan or profit charges?

Some calculators display an estimate, but the method varies by institution. The charge may be described as Upah Simpan, ujrah, a profit charge or another product-specific term. The rate, billing interval, calculation base and payment timing may also differ.

For example, the Sahabat calculator currently displays one-month and 12-month profit outputs and shows a provider-specific formula based on financing and an Upah rate. (sahabatarrahnu.com.my) The Ar-Rahnu Emas calculator displays a different product structure, including rates and a formula using marhun value, days and a 365-day divisor. Its displayed formula should be treated as specific to that provider and product, not as a universal Ar-Rahnu formula. (arrahnuemas.com.my)

Before relying on a fee estimate, confirm:

• Whether the rate is monthly, annualised or expressed in another unit
• Whether the charge is based on marhun value, financing amount or another balance
• Whether the calculator uses actual days, whole months or a fixed period
• When charges are payable
• Whether settlement, renewal, stamp duty, agency or auction-related fees apply
• Whether taxes or other charges may be added

Can one calculator compare different Ar-Rahnu institutions?

Only if it lets you change the provider-specific assumptions. A useful comparison sheet should allow separate entries for:

1. Provider price per gram by purity

2. Eligible weight after excluding non-gold components

3. Available financing margin

4. Minimum and maximum financing limits

5. Upah Simpan, ujrah or profit-charge method

6. Existing principal and settlement charges

7. Maturity and extension rules

8. Any provider-specific fees

For example, Co-opbank Pertama currently advertises financing of up to 80% of marhun value, a financing period of up to 18 months, and accepted gold standards including 750, 835, 875, 916, 950 and 999. Its page also lists provider-specific fees and limits. These details are product terms, not assumptions that should be applied to every institution. (cbp.com.my)

TEKUN’s current conditions page lists accepted standards from 18.0K/75.00% through 24.0K/99.90%, financing of up to 80% of marhun value, a stated individual maximum of up to RM300,000, and a storage-fee description based on marhun value. Because such terms can change, check the current effective terms before entering them into a comparison calculator. (tekun.gov.my)

What should I enter into a practical Ar-Rahnu calculator?

At minimum, enter:

• Gold weight in grams
• Karat, fineness or purity
• Provider price per gram
• Eligible-weight adjustment, if applicable
• Financing margin
• Existing principal, if replacing or settling an active Surat Pajak
• Accrued charges to the calculation date
• Maturity date and intended repayment or extension date

A more complete model can show:

• Estimated marhun value
• Financing at several margins
• Estimated charges by date
• Net cash after settling an existing ticket
• Remaining principal after partial redemption
• A price-sensitivity range rather than one fixed gold price

The model should label every result as an estimate and identify which values came from the provider and which were entered by the user.

Is “retained equity” a standard Ar-Rahnu measure?

Not necessarily. The phrase can be used as a custom risk metric, but it should not be presented as a universal Ar-Rahnu accounting term.

One illustrative version is:

```text

Estimated net collateral buffer = current estimated collateral value

− outstanding financing

− accrued charges

− expected redemption or settlement costs

```

This is more complete than subtracting only the financing amount. The result can change when the provider updates its price, the branch excludes part of the item, charges accrue or the customer makes a payment.

If a particular website calls this measure “retained equity,” treat that as the website’s own definition. It is not a guarantee that the institution will use the same metric.

What about shortfall, maturity and auction risk?

A calculator can help you monitor assumptions, but it cannot predict or prevent an auction. The customer must follow the issuing institution’s maturity, extension and payment procedures.

Do not assume that every provider offers automatic extensions or uses the same process. TEKUN’s published conditions, for example, describe a six-month financing period and a 6 + 6 extension structure, while other providers may use different periods or conditions. (tekun.gov.my)

The treatment of auction proceeds, fees and any remaining surplus also depends on applicable Malaysian law, the provider’s contract and the auction procedure. Do not assume that any surplus is automatically paid in the same way by every institution; obtain the provider’s written terms and settlement statement.

You can reduce avoidable risk by recording each Surat Pajak separately:

• Pledged weight and purity
• Provider and branch
• Principal granted
• Charges paid and accrued
• Maturity date
• Extension conditions
• Current provider price
• Amount needed for redemption or settlement

What is the best calculator for my situation?

• For one institution: Use that institution’s current Ar-Rahnu calculator and price table.
• For comparing margins: Use a tool that displays several financing percentages, such as 60%, 65%, 70%, 75% and 80% where offered. (sahabatarrahnu.com.my)
• For comparing providers: Use a spreadsheet or calculator that allows separate provider prices, margins, fee rules and eligibility assumptions.
• For an existing Surat Pajak: Add accrued charges, settlement costs and the exact maturity date instead of calculating only the initial financing.

Avoid choosing an 80% margin simply because it is available. A lower margin may reduce the amount of cash received but leave more room for price changes, charges and repayment delays.

FAQ

Does the calculator determine my Ar-Rahnu margin?

No. The institution determines the available financing margin and final approved amount. The calculator applies an assumed or provider-displayed margin to an estimated marhun value.

What purity should I enter?

Enter the karat or fineness used by the selected provider, such as 916, 999 or the equivalent karat value. If the item contains stones or non-gold parts, the provider may value less than the total scale weight.

Can I use today’s gold price from another website?

It is better to use the selected institution’s current Ar-Rahnu price per gram for the relevant purity. Prices and appraisal rules differ by provider and can change without making an older calculator result valid.

Do calculator results include all fees?

Not necessarily. Check whether the tool includes Upah Simpan, ujrah, profit charges, agency fees, stamp duty, settlement costs, renewal charges or auction-related costs. Fee terminology and formulas vary by product.

Is the calculator result binding?

No. It is an estimate only. The institution’s branch appraisal, eligibility checks, current price, approved margin, contract and final settlement statement control the transaction.

Can I compare two providers using the same margin?

You can compare scenarios using the same percentage, but the result may still be misleading if the providers use different prices, eligible-weight rules, fee formulas, limits or maturity terms.

Does a calculator show whether my gold will be accepted?

Usually not with certainty. Acceptance may depend on the item’s construction, purity, condition, stones, certification and the provider’s current policy. Confirm eligibility with the institution or branch before relying on the estimate.

Can a calculator guarantee that my gold will not be auctioned?

No. It can help track dates, debt and estimated buffers, but it cannot confirm an extension, repayment arrangement or auction outcome. Follow the provider’s written terms and contact the branch before the maturity date if repayment may be difficult.
