What is Vaddi?
Vaddi means interest — the extra amount paid on borrowed money.
Basic Terms:
- Principal (Asalu) → Original amount borrowed
- Interest (Vaddi) → Extra amount paid
- Rate (R) → Percentage charged
- Time (T) → Duration of loan
In rural India, interest is usually quoted per month, not per year.
For example:
- ₹1 per ₹100 per month = 1% monthly
- ₹2 per ₹100 per month = 2% monthly
This style is very common in private lending.
Baru Vaddi (Simple Interest) – Detailed Explanation
Baru Vaddi means Simple Interest.
Interest is calculated only on the original principal. It does NOT increase every month.
📌 Simple Interest Formula
\(SI = \frac{P \times R \times T}{100}\)Where:
- P = Principal
- R = Rate of Interest
- T = Time (Months or Years)
Total Amount:
\(A = P + SI\)Example 1 – 2 Rupees Vaddi (Monthly)
Loan Details:
- Principal = ₹1,00,000
- Rate = 2% per month
- Time = 12 months
Step 1:
\(SI = \frac{100000 \times 2 \times 12}{100}\)Step 2:
\(SI = 24000\)Final Amount:
- Interest = ₹24,000
- Total Repayment = ₹1,24,000

Example 2 – 1 Rupee Vaddi (Monthly)
Loan:
- Principal = ₹50,000
- Rate = 1% per month
- Time = 18 months
Final:
- Interest = ₹9,000
- Total = ₹59,000

Why Monthly Vaddi Becomes Expensive
People often ignore the annual impact.
2% Monthly means:
2 × 12 = 24% yearly
3% Monthly means:
3 × 12 = 36% yearly
Comparison:
| Monthly Rate | Yearly Equivalent |
|---|---|
| 1% | 12% |
| 2% | 24% |
| 3% | 36% |
| 5% | 60% |
Village interest rates can be much higher than bank loans.
Chakra Vaddi (Compound Interest)
Chakra Vaddi means Compound Interest.
Interest is added to principal regularly, and future interest is calculated on the new total.
Banks use this method.
Compound Interest Formula
\(A = P\left(1+\frac{r}{n}\right)^{nt}\)Where:
- A = Final Amount
- P = Principal
- r = Annual Rate (decimal)
- n = Compounding frequency
- t = Years
Interest:
\(CI = A – P\)Example – Monthly Compounding
- Principal = ₹2,00,000
- Annual Rate = 18%
- Compounded monthly
- Time = 2 years
Final Amount ≈ ₹2,86,900
Interest ≈ ₹86,900
Notice how compound interest grows faster than simple interest.
Daily Vaddi Calculation Formula
Sometimes loans are calculated per day.
Daily Rate Formula:
\(Daily\ Rate = \frac{Monthly\ Rate}{30}\)Example:
2% monthly →
2 ÷ 30 = 0.066% per day
Daily Interest Formula:
\(SI = \frac{P \times R \times Days}{100}\)Date-Wise Vaddi Calculation (Exact Method)
If you know start and end date:
Step 1: Calculate duration in years, months, days
Example:
1 Jan 2024 to 15 April 2025
= 1 year 3 months 14 days
Step 2: Convert to months
1 year = 12 months
14 days ≈ 0.46 months
Total = 15.46 months
Step 3: Apply formula
\(SI = \frac{P \times R \times 15.46}{100}\)For exact automatic result use:

Real Village Lending Scenarios
Scenario 1 – Interest Paid Monthly
Principal = ₹1,00,000
Rate = 2% monthly
Monthly Interest = ₹2,000
If borrower pays ₹2,000 every month, principal remains ₹1,00,000.
Scenario 2 – Interest Not Paid for 6 Months
Principal = ₹1,00,000
2% monthly
6 months interest = ₹12,000
If lender adds it to principal:
New Principal = ₹1,12,000
Next month interest increases.
This slowly becomes compound-style growth.
Common Mistakes in Vaddi Calculation
❌ Confusing monthly rate with yearly rate
❌ Ignoring extra days
❌ Not confirming simple or compound method
❌ Not calculating total repayment before borrowing

FaQs
What is the difference between Baru Vaddi and Chakra Vaddi?
Baru Vaddi means Simple Interest, where interest is calculated only on the original principal.
Chakra Vaddi means Compound Interest, where interest is added to the principal and future interest is calculated on the increased amount.
Is 2 Rupees Vaddi high?
Yes.
2% per month equals 24% per year (simple basis).
Compared to bank loans (usually 8%–15% annually), it is considered high.
What happens if interest is not paid monthly?
In many private loans, unpaid interest may be added to the principal.
This increases the total amount and works similar to compound interest.
