📊 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
