🧮 Calculation engine (institutional formulas)

cashflow & liquidity

dailyNet = totalInward – totalOutward

runningBalance = openingBalance + totalInward – totalOutward

pendingLiability = SUM(outward cheques not cleared)

weeklyBurn = SUM(outward, last 7d) / 7

projectedMonthEnd = currentBalance + (avgDailyNet × remainingDays)

ROI & portfolio

ROI = ((currValuation – investCost) / investCost) × 100

annualizedROI = ((1 + ROI/100)^(365/holdingDays) – 1) × 100

portfolioWeight = (companyInvest / totalPortfolio) × 100

HHI = Σ(portfolioWeight²) [target < 1500]
