How is simple interest calculated?
Multiply the amount by the rate and the time. Simple interest is charged on the original amount only, for every year it is borrowed or deposited:
Interest = P × R × T ÷ 100
P is the principal, R the rate in % a year and T the time in years (months ÷ 12, days ÷ 365; with a rate a month, days ÷ 30 for the months).
Example: ₹1,00,000 at 12% a year for 2 years earns ₹24,000 interest; ₹1,24,000 in all.
Rupee interest (రూపాయి వడ్డీ): how to calculate it
Family and village loans are often quoted as rupees per ₹100 per month: "one rupee interest" is ₹1 on every ₹100 each month, which is 12% a year; "two rupees" is 24% a year. The interest is the amount × the rupees × the months ÷ 100: ₹50,000 at ₹2 for 6 months is ₹6,000 interest, ₹1,000 a month. Choose "₹ per ₹100 a month" above to type it that way.
Rupee interest in percentage: 75 paise, ₹1, ₹2
Multiply by 12: 75 paise per ₹100 a month is 9% a year, ₹1 is 12%, ₹2 is 24%. Each, with the interest a month on ₹1 lakh:
| Per ₹100 a month | % a year | Interest a month on ₹1 lakh |
|---|---|---|
| 50 paise | 6% | ₹500 |
| 75 paise | 9% | ₹750 |
| 1 rupee | 12% | ₹1,000 |
| 1 rupee 25 paise | 15% | ₹1,250 |
| 1 rupee 50 paise | 18% | ₹1,500 |
| 2 rupees | 24% | ₹2,000 |
| 2 rupees 50 paise | 30% | ₹2,500 |
| 3 rupees | 36% | ₹3,000 |
The other way, divide by 12: 7.5% a year is 62.5 paise, 10% a year is 83.33 paise, 18% a year is 1 rupee 50 paise.
వడ్డీ లెక్కలు ఎలా చేయాలి?
వడ్డీ = అసలు × రూపాయి వడ్డీ × నెలలు ÷ 100. ఉదాహరణకు ₹50,000కు ₹2 వడ్డీతో 6 నెలలకు వడ్డీ ₹6,000, నెలకు ₹1,000. రూపాయి వడ్డీ అంటే నెలకు ₹100కు ₹1, అంటే ఏడాదికి 12%; రెండు రూపాయలు 24%, 75 పైసలు 9%. అసలు మీద మాత్రమే వేసే ఈ వడ్డీని సాధారణ వడ్డీ (బారువడ్డీ) అంటారు; వడ్డీ మీద వడ్డీ అయితే చక్రవడ్డీ కాలిక్యులేటర్ చూడండి.
Questions
Simple or compound interest: what is the difference?
Simple interest never charges interest on interest. With compound interest, unpaid interest is added to the principal, so the next period's interest is higher. Over long periods compound interest grows much faster: see the compound interest calculator.
How are days counted?
With a rate a year, on a 365-day year, as banks do for most deposits and loans: 73 days is 0.2 of a year, so ₹36,500 at 10% earns ₹730. With a rate a month (rupee interest), a month counts as 30 days, as such loans are reckoned: 45 days is 1.5 months, so ₹50,000 at ₹2 is ₹1,500.
How do I work out the interest from one date to another?
Count the days with the days between dates calculator, then choose "Days" under "Time in" above and type them.
I know what came back: what rate was it?
Choose "Work out: Rate" and type the amount lent, the amount returned with interest and the time: the calculator gives the rate in % a year and as rupee interest.
