Interest Calculations
Interest calculations form the foundation of financial mathematics, covering simple and compound interest formulas․ These are crucial for evaluating investment growth and loan repayments, as detailed in the PDF guide․
2․1․ Simple Interest Formula
The simple interest formula, I = P * r * t, calculates interest earned on the principal amount․ Here, P is the principal, r is the annual interest rate, and t is the time in years․ Unlike compound interest, simple interest does not accrue on previously earned interest, making it straightforward for short-term financial calculations․ This method is widely used for evaluating loans and investments, as detailed in the PDF guide․
2․2․ Compound Interest Formula
The compound interest formula, A = P(1 + r/n)^(nt), calculates the future value of an investment․ Here, A is the amount, P is the principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years․ This formula accounts for interest earned on both the principal and accrued interest, making it ideal for long-term investments․ It is widely used for savings accounts, bonds, and mortgages, as explained in the PDF guide;
Present and Future Value Calculations
These calculations determine the worth of money over time, essential for financial decisions․ The PDF guide provides formulas for present value (PV) and future value (FV) calculations․
3․1․ Present Value of a Single Sum
The present value (PV) of a single sum calculates the current worth of a future amount, discounted at a specified interest rate․ The formula is PV = FV / (1 + i)^n, where FV is the future value, i is the interest rate, and n is the number of periods․ This concept is crucial for evaluating investments and determining the value of future cash flows in today’s terms, as explained in the PDF guide․
3․2․ Future Value of a Single Sum
The future value (FV) of a single sum determines the projected worth of an initial investment or deposit, grown at a specified interest rate over time․ The formula is FV = PV * (1 + i)^n, where PV is the present value, i is the interest rate, and n is the number of periods․ This calculation is essential for understanding investment growth and planning future financial needs, as detailed in the PDF guide․
Annuity Calculations
Annuity calculations involve determining the present or future value of a series of periodic payments․ Key formulas include present value of ordinary annuities and annuities due, as detailed in the PDF guide․
4․1․ Ordinary Annuity (Payment at the End of the Period)
An ordinary annuity involves payments made at the end of each period․ The present value (PV) is calculated using the formula:
PV = PMT × [(1 ― (1 + r)^-n) / r], where PMT is the periodic payment, r is the interest rate, and n is the number of periods․ This formula is essential for evaluating investments and loans with end-of-period cash flows, as detailed in the PDF guide․
4․2․ Annuity Due (Payment at the Beginning of the Period)
An annuity due involves payments made at the beginning of each period․ The present value (PV) is calculated using the formula:
PV = PMT × [(1 ― (1 + r)^-n) / r] × (1 + r), where PMT is the periodic payment, r is the interest rate, and n is the number of periods․ This formula accounts for the time value of money when payments occur at the start of each period, as explained in the PDF guide․
Investment Project Analysis
Investment project analysis evaluates viability using formulas like NPV and IRR․ NPV calculates net value by discounting cash flows, while IRR determines the rate yielding zero NPV․ These metrics guide decision-making, ensuring projects meet financial goals and risks are assessed․ The PDF guide provides detailed formulas and examples for accurate project evaluation in financial mathematics․
5․1․ Net Present Value (NPV) Formula
The NPV formula calculates the difference between the present value of cash inflows and the present value of cash outflows over a period․ It is expressed as:
NPV = ∑ (CF_t / (1 + r)^t) ― Initial Investment
Where CF_t is the cash flow at time t, r is the discount rate, and t is the time period․ A positive NPV indicates a profitable project, while a negative NPV suggests it is not viable․ This formula is crucial for evaluating investment opportunities and aligning with financial goals, as detailed in the PDF guide․
5․2․ Internal Rate of Return (IRR) Formula
The IRR is the discount rate that equates the NPV of an investment to zero․ The formula is:
0 = ∑ (CF_t / (1 + IRR)^t) ― Initial Investment
Where CF_t is the cash flow at time t, and IRR is the internal rate of return․ Unlike NPV, IRR provides a percentage return, making it easier to compare projects․ It is widely used in investment analysis to determine profitability, as detailed in the PDF guide․
Risk and Return Analysis
This section explores the relationship between risk and return, focusing on the Capital Asset Pricing Model (CAPM) and portfolio risk management, as detailed in the PDF guide․
6․1․ Capital Asset Pricing Model (CAPM) Formula
The Capital Asset Pricing Model (CAPM) formula calculates the expected return on an investment based on its risk․ It is expressed as:
E(R) = R_f + β(R_m ― R_f), where:
– E(R) is the expected return,
– R_f is the risk-free rate,
– β measures the asset’s volatility relative to the market, and
– R_m is the market return․ This formula helps investors assess the required return for an investment’s risk level, guiding portfolio decisions and asset pricing strategies, as detailed in the PDF guide․
6․2․ Portfolio Risk and Return Formulas
Portfolio risk and return formulas quantify the relationship between diversification, risk, and potential returns․ The expected return of a portfolio is calculated as:
E(R_p) = Σ(w_i * E(R_i)), where w_i is the weight of asset i and E(R_i) is its expected return․ Portfolio risk, measured by variance, is:
σ_p² = Σ(w_i²σ_i²) + 2Σ(w_iw_jCov(i,j)), where σ_i² is the variance of asset i and Cov(i,j) is the covariance between assets i and j․ These formulas help investors optimize portfolios for desired risk-return profiles, as detailed in the PDF guide․
Financial Derivatives
Financial derivatives include options, futures, and forwards, essential for hedging and speculation․ Key formulas like the Black-Scholes model for options and futures pricing are covered in detail․
7․1․ Option Pricing Formulas (Black-Scholes Model)
The Black-Scholes model is a cornerstone in financial derivatives pricing․ It calculates the theoretical price of a European call option using the formula:
C = S₀ * N(d₁) ― K * e^(-rT) * N(d₂)
where S₀ is the stock price, K is the strike price, r is the risk-free rate, T is time to maturity, and N is the cumulative distribution function of the standard normal distribution․ The variables d₁ and d₂ are calculated as:
d₁ = (ln(S₀/K) + (r + σ²/2)T) / (σ√T)
d₂ = d₁ ― σ√T
This model assumes lognormal stock price distribution and constant volatility․ It is widely used for pricing options and understanding derivative risks․ For detailed insights, refer to the Black-Scholes PDF guide․
7․2․ Futures and Forwards Pricing Formulas
Futures and forwards are over-the-counter (OTC) and exchange-traded derivatives․ The pricing formula for futures is based on the no-arbitrage principle:
F = S₀ * e^(rT)
where F is the futures price, S₀ is the spot price, r is the risk-free rate, and T is time to maturity․ Forwards use a similar formula but account for storage costs and dividends․ These contracts allow hedging against price fluctuations, making them essential tools in risk management․ For detailed calculations and examples, refer to the futures pricing guide․
Budgeting and Cost Analysis
Budgeting involves creating financial plans to allocate resources efficiently․ Cost analysis evaluates expenses to optimize spending․ Key formulas include cost-benefit analysis and break-even analysis, essential for informed financial decision-making․
8․1․ Cost-Benefit Analysis Formula
The Cost-Benefit Analysis Formula evaluates project viability by comparing total benefits to total costs․ The formula is:
Benefit-Cost Ratio = (Total Benefits / Total Costs)․
When the ratio exceeds 1, the project is profitable․ This method helps prioritize investments and allocate resources efficiently․ Refer to the PDF guide for detailed examples and applications․
8․2․ Break-Even Analysis Formula
The Break-Even Analysis Formula calculates the point where total revenues equal total costs, ensuring no profit or loss․ The formula is:
BEP = Fixed Costs / (Selling Price ⏤ Variable Costs)․
This tool helps businesses determine the production volume or sales required to break even, enabling informed decisions on pricing and cost management․ For further details, refer to the PDF guide․
