**Before (Lottery):**
|
||
```
|
||

Simple but not traditional chit fund

|
||
| 400px wide | Full screen width |
|
||

|
||
| Overflow errors | No overflow |
|
||
| Cramped | Spacious |
|
||
| Single scroll | Separate steps |
|
||
|
||
### **Information Display:**
|
||
| Before | After |
|
||

|
||
| Fixed win amount | Varying lift amounts |
|
||
| No month dates | Shows actual dates (Mar-25, Apr-25) |

|
||
|
||
## 📊 **New Calculations Match Your Sample**
|
||
|
||
Your sample shows **Month 1 Lifter Gets ₹1,75,300**
|
||
|
||
Our calculation:
|
||
```
|
||
Target Value: ₹2,00,000
|
||
Month: 1
|
||
Starting Percentage: 87.65%
|
||
|
||
Lift Amount = ₹2,00,000 × 87.65%
|
||
= ₹1,75,300 ✅
|
||
|
||
EXACT MATCH!
|
||
```
|
||
|
||
Your sample shows **Month 2 increase of ₹2,600**
|
||
|
||
Our calculation:
|
||
```
|
||
Increment = (99.35% - 87.65%) / 9
|
||
= 11.7% / 9
|
||
= 1.3% per month
|
||
|
||
In rupees = ₹2,00,000 × 1.3%
|
||
= ₹2,600 ✅
|
||
|
||
EXACT MATCH!
|
||
```
|
||
|

|
||
|
||
## 💰 **Why This Formula?**
|
||
|
||
### **Economic Reasoning:**
|
||
|
||
**Early Lifter (Month 1):**
|
||
- Needs money urgently
|
||
- Willing to accept ₹1,75,300 instead of ₹2,00,000
|
||
- Discount of ₹24,700 (12.35%)
|
||
- This discount is distributed to other members
|
||
- **Benefit:** Gets large sum immediately with minimal investment
|
||
|
||
**Late Lifter (Month 10):**
|
||
- Waited patiently
|
||
- Paid all months (₹1,02,500 total)
|
||
- Received dividends each month
|
||
- Gets ₹1,98,700 (almost full value)
|
||
- **Benefit:** Like earning interest on savings
|
||
