Islamic Loan (Qarz-e-Hasana) Calculator
Islamic Loan (Qarz-e-Hasana) Calculator and Riba-Free Finance Guide
Qarz-e-Hasana (Beautiful Loan / Interest-Free Loan) is one of the most virtuous financial acts in Islam. Allah Himself calls it a "loan to Allah" in the Quran and promises to multiply its reward manifold. This calculator helps you plan interest-free loan repayments, compare Islamic vs conventional financing, and understand the devastating prohibition of Riba (interest) in Islam.
Loan Details
Qarz-e-Hasana Formulas
Basic Repayment Formula (Interest-Free)
Where:
EMI = Equal Monthly Installment
L = Total Loan Amount
T = Number of months for repayment
This is the beauty of Qarz-e-Hasana: You repay EXACTLY what you borrowed. No interest. No hidden charges. No compounding. No penalty.
Bank Loan (Riba) EMI Formula
Where:
L = Loan amount
r = Monthly interest rate (Annual rate / 12 / 100)
n = Total number of months
Total Payment = EMI x n
Total Interest = (EMI x n) - L
This formula shows how interest compounds over time, making you pay far more than you borrowed.
Interest Saved Formula
Interest Saved = Bank Total - Qarz Amount
Percentage Saved = (Interest Saved / Qarz Amount) x 100
Affordability Formula
Below 20% = Comfortable
20-30% = Manageable
30-40% = Tight but possible
Above 40% = Too risky — consider longer repayment period
Solved Examples
Example 1: Small Qarz — Personal Need
Borrowed PKR 1,00,000 from a friend for medical emergency. Repaying in 6 months. Income: PKR 50,000.
EMI = 1,00,000 / 6 = PKR 16,667/month
Total repaid = PKR 1,00,000 (exact amount)
Income used = (16,667/50,000) x 100 = 33.3%
If this was a bank loan at 25%:
r = 25/12/100 = 0.02083
EMI = 1,00,000 x 0.02083 x (1.02083)6 / [(1.02083)6 - 1]
EMI = PKR 17,814
Total = 17,814 x 6 = PKR 1,06,885
Interest = PKR 6,885
Interest saved by Qarz-e-Hasana = PKR 6,885 (6.9% of loan)
Example 2: Business Qarz — Medium Term
Borrowed PKR 5,00,000 for small business. Repaying in 2 years. Income: PKR 80,000.
EMI = 5,00,000 / 24 = PKR 20,833/month
Total = PKR 5,00,000 | Interest = PKR 0
Income % = 26% (manageable)
Bank loan at 22%:
EMI = PKR 25,824
Total = 25,824 x 24 = PKR 6,19,776
Interest paid = PKR 1,19,776
Saved = PKR 1,19,776 (24% of loan amount)
Example 3: Home Purchase — Long Term Comparison
Home worth PKR 50,00,000. Compare: Qarz from family vs Bank mortgage at 18% for 20 years.
EMI = 50,00,000 / 240 months = PKR 20,833/month
Total = PKR 50,00,000
Bank Mortgage at 18% (20 years):
EMI = PKR 77,103/month
Total = 77,103 x 240 = PKR 1,85,04,720
Interest = PKR 1,35,04,720
You pay 2.7x the house price with bank loan
Saved with Qarz-e-Hasana = PKR 1,35,04,720 (270% of original price)
This is why Riba is called "war against Allah and His Messenger" in Quran 2:279.
Example 4: Car Loan Comparison
Car price: PKR 30,00,000. Bank auto loan 20% for 5 years vs Qarz-e-Hasana.
EMI = 30,00,000 / 60 = PKR 50,000/month
Total = PKR 30,00,000
Bank Auto Loan at 20%:
EMI = PKR 79,463/month
Total = 79,463 x 60 = PKR 47,67,780
Interest = PKR 17,67,780
Saved = PKR 17,67,780 (59% extra you pay in Riba)
That interest amount could buy another small car.
Example 5: With Grace Period
Borrowed PKR 2,00,000. Grace period: 3 months. Then repay in 12 months. Income: PKR 60,000.
Active repayment: 12 months
Total timeline: 15 months
EMI = 2,00,000 / 12 = PKR 16,667/month
Months 1-3: PKR 0 (grace)
Months 4-15: PKR 16,667 each
Total = PKR 2,00,000 | Interest = PKR 0
Riba (Interest) in Islam — Complete Guide
What is Riba?
Riba literally means "increase" or "excess." In Islamic finance, it refers to any guaranteed, predetermined return on a loan or financial transaction regardless of the outcome. There are two types:
| Type | Arabic | Description | Example |
|---|---|---|---|
| Riba an-Nasiah | ربا النسیئہ | Interest charged on loans — extra money charged for lending over time | Bank charges 20% interest on personal loan |
| Riba al-Fadl | ربا الفضل | Unequal exchange of same commodity — trading gold for gold with excess | Exchanging 10g gold for 12g gold |
Severity of Riba in Quran
Allah says: "Those who consume Riba will not stand (on the Day of Resurrection) except like the standing of a person beaten by Shaitan (Satan) leading him to insanity. That is because they say: 'Trading is like Riba,' but Allah has permitted trading and has forbidden Riba."
— Quran 2:275
Allah says: "Allah destroys Riba and gives increase for charity. And Allah does not like every sinning disbeliever."
— Quran 2:276
Allah says: "O you who believe! Fear Allah and give up what remains of Riba if you are truly believers. If you do not, then be warned of a WAR from Allah and His Messenger."
— Quran 2:278-279
Allah says: "O you who believe! Do not consume Riba, doubled and multiplied, and fear Allah that you may be successful."
— Quran 3:130
Severity of Riba in Hadith
The Prophet (PBUH) said: "Allah has cursed the one who consumes Riba, the one who pays it, the one who writes it down, and the two witnesses to it." He said: "They are all the same (in sin)."
— Sahih Muslim 1598
The Prophet (PBUH) said: "Riba has seventy-three doors (levels of sin). The least of them is like a man committing incest with his own mother."
— Sunan Ibn Majah 2274
The Prophet (PBUH) said: "A dirham of Riba that a person consumes knowingly is worse in the sight of Allah than thirty-six acts of fornication."
— Musnad Ahmad 21957

Qarz-e-Hasana Rules in Islam
| Rule | Detail |
|---|---|
| Repay Exact Amount | Borrow PKR 1,00,000 = Return PKR 1,00,000. Not a single rupee more can be demanded. |
| No Benefit to Lender | Lender cannot receive any material benefit — no interest, no gifts as condition, no services. Their reward is from Allah alone. |
| Written Agreement | Quran 2:282 commands writing down debt agreements with witnesses. This protects both parties. |
| Set Repayment Date | Both parties should agree on a repayment schedule. Open-ended loans cause disputes. |
| Borrower Must Intend to Repay | Taking a loan with intention of not repaying is a major sin. The Prophet (PBUH) said such a person will meet Allah as a thief. |
| Lender Should Be Patient | If borrower is in genuine difficulty, the lender should give more time. Quran 2:280 says "grant a delay until hardship is relieved." |
| Voluntary Extra Payment | The borrower CAN voluntarily return more than borrowed as a gift (not condition). The Prophet (PBUH) used to return more when repaying as a kindness — but this must never be a condition. |
| Forgiving Debt | If you forgive someone's debt, it counts as Sadaqah and is hugely rewarded. "If you give charity, that is better for you, if you only knew" (Quran 2:280). |
Reward of Giving Qarz-e-Hasana
Allah says: "Who is it that will lend to Allah a beautiful loan (Qarz-e-Hasana), so that He may multiply it for him many times? Allah restricts and expands (provisions), and to Him you shall return."
— Quran 2:245
Allah says: "If you lend to Allah a beautiful loan, He will multiply it for you and forgive you. And Allah is Most Appreciative, Most Forbearing."
— Quran 64:17
The Prophet (PBUH) said: "Every loan is a Sadaqah." (Meaning: every time the lender waits for repayment, they earn the reward of charity for that period.)
— Tabarani, authenticated by Al-Albani
The Prophet (PBUH) said: "I saw written on the gate of Paradise: Sadaqah is rewarded ten times, and a loan is rewarded eighteen times." A companion asked why loan is more. He said: "Because the person who asks for a loan asks out of genuine need, while the beggar may ask even when he has enough."
— Sunan Ibn Majah 2431
Frequently Asked Questions
Q: Can the lender charge any fee for Qarz-e-Hasana?
A: No. Any charge, fee, or benefit linked to the loan makes it Riba. The lender's only reward is from Allah. However, actual administrative costs (like document preparation) that do not generate profit can be charged according to some scholars.
Q: Can I give a gift to the lender after repaying?
A: If the gift was NOT a condition of the loan and is given voluntarily out of gratitude, it is permissible and even praiseworthy. The Prophet (PBUH) used to return more than he borrowed as a gesture of kindness. But if the gift was a pre-condition, it becomes Riba.
Q: Is inflation adjustment permissible?
A: This is debated among scholars. Most classical scholars say the exact same amount must be returned (e.g., borrowed PKR 1,00,000 = return PKR 1,00,000 regardless of inflation). Some modern scholars allow inflation indexing for very long-term loans to maintain fairness. Consult your local Mufti.
Q: What if the borrower cannot repay on time?
A: The Quran explicitly says: "If the debtor is in difficulty, grant them time till it is easy for them to repay. But if you remit it (forgive the debt) as charity, that is better for you, if you only knew" (Quran 2:280). Pressuring a genuinely struggling debtor is sinful.
Q: Are Islamic bank products truly interest-free?
A: Islamic banks use Shariah-compliant structures (Murabaha, Ijarah, Musharakah) that are technically different from conventional interest. However, there is ongoing debate among scholars about whether some Islamic banking products are truly halal or merely Riba in disguise. Research carefully and consult trusted scholars.
Q: Is it better to give Qarz or Sadaqah?
A: According to the Hadith above, Qarz earns 18x reward while Sadaqah earns 10x. This is because the borrower is in genuine need and maintains their dignity by borrowing instead of begging. However, giving Sadaqah to someone too proud to ask is also immensely rewarding.
Q: Can a business charge profit on goods sold on installments?
A: Yes. Selling goods at a higher price for deferred payment (installments) is permissible in Islam — this is Murabaha (cost-plus sale). The key difference: it must be a genuine sale of a real item with disclosed profit margin, not a money loan with interest.
Q: What about credit cards?
A: If you pay the full balance before the interest-free period ends, most scholars consider credit card usage permissible. If you carry a balance and pay interest, it is Riba and haram. Some scholars prohibit credit cards entirely as they involve a Riba-based contract even if you pay on time.
