Below is a consolidated list of commonly used financial equations across different areas of finance.

1. Banking & Loan Formulas

• Loan EMI: EMI = [P × r × (1+r)ⁿ] / [(1+r)ⁿ – 1]
• Compound Interest: FV = PV × (1 + r)ⁿ
• Simple Interest: SI = P × r × t
• Present Value: PV = FV / (1 + r)ⁿ
• Future Value (Single Sum): FV = PV × (1 + r)ⁿ
• Annual Percentage Rate (APR): APR = (1 + r/m)ᵐ – 1 (nominal rate)
• Effective Annual Rate (EAR): EAR = (1 + r/m)ᵐ – 1
• Discount Factor: DF = 1 / (1 + r)ⁿ

2. Annuities

• Present Value of Ordinary Annuity: PV = C × [1 – (1 + r)⁻ⁿ] / r
• Future Value of Ordinary Annuity: FV = C × [(1 + r)ⁿ – 1] / r
• Present Value of Annuity Due: PV = C × [1 – (1 + r)⁻ⁿ] / r × (1 + r)
• Future Value of Annuity Due: FV = C × [(1 + r)ⁿ – 1] / r × (1 + r)

3. Capitalization & Discounting

• Simple Capitalization: Cₙ = C₀ × (1 + i × n)
• Compound Capitalization: Cₙ = C₀ × (1 + i)ⁿ
• Simple Discount: C₀ = Cₙ × (1 – d × n)
• Compound Discount: C₀ = Cₙ / (1 + d)ⁿ

4. Amortization

• Monthly Payment (French Loan): M = [P × r × (1 + r)ⁿ] / [(1 + r)ⁿ – 1]
• Interest Payment: I = Outstanding Balance × r
• Principal Payment: A = Monthly Payment – Interest Payment

5. Corporate Finance

• Net Present Value (NPV): NPV = Σ [CFₜ / (1 + r)ᵗ] – Initial Investment
• Internal Rate of Return (IRR): r where NPV = 0
• Weighted Average Cost of Capital (WACC): WACC = (E/V) × rₑ + (D/V) × rₐ × (1 – T)
• Earnings Per Share (EPS): EPS = Net Income / Shares Outstanding

6. Investment & Valuation

• Dividend Discount Model (DDM): P₀ = D₁ / (r – g)
• Price-to-Earnings (P/E) Ratio: P/E = Market Price per Share / EPS
• Capital Asset Pricing Model (CAPM): r = r_f + β × (r_m – r_f)
• Portfolio Expected Return: E(Rₚ) = Σ wᵢ × E(Rᵢ)
• Portfolio Variance: σₚ² = Σ Σ wᵢ × wⱼ × Cov(Rᵢ, Rⱼ)

7. Fixed Income

• Yield to Maturity (YTM): Solve for r in PV = Σ [Cₜ / (1 + r)ᵗ] + F / (1 + r)ⁿ
• Bond Price: P = Σ [C / (1 + r)ᵗ] + F / (1 + r)ⁿ

8. Derivatives

• Black-Scholes Option Pricing: C = S × N(d₁) – X × e^(-rT) × N(d₂)
  where d₁ = [ln(S/X) + (r + σ²/2)T] / (σ√T)
  d₂ = d₁ – σ√T

9. Economic Indicators

• Gross Domestic Product (GDP): GDP = C + I + G + (X – M)
• Inflation Rate: π = (P₁ – P₀) / P₀ × 100%
• Unemployment Rate: U = (Number of Unemployed / Labor Force) × 100%

These equations cover core areas of finance and are widely used in personal finance, corporate finance, investment analysis, and economic modeling.
