Girvi interest calculator
Simple interest on a girvi (gahan) gold loan at a monthly rate, counted by the days between the pledge and today, with an optional minimum period. The same rule Infovion JMS uses for its girvi register.
Simple interest, 30 days = one month. Part-payments lower the interest from the day they are made; JMS works that out on every pledge.
How girvi interest is calculated
Most jewellers charge simple interest at a monthly rate: interest = loan amount × rate per month × number of days ÷ 30. At 2% a month, ₹50,000 earns ₹1,000 a month, or about ₹33.33 a day.
Some shops count whole months instead, charging a full month for any part month, and many charge a minimum period such as 15 days or a month even when the gold is released earlier.
When the customer pays back part of the loan, interest from that day is charged only on the amount still outstanding. Interest payments reduce the interest due, not the loan.
Money lending in India is regulated by state money-lenders acts, which can set licences and maximum rates. Check the rules in your state.
