Essential Finance Formulas
Compound Interest Formula:
Compound interest is interest computed on both the original principle and prior periods’ accrued interest. The compound interest formula is:
A = P(1 + r/n)^(nt)
Where:
A = Final amount (including interest)
P = Principal amount (initial investment)
r = r represents the annual interest rate, expressed as a decimal.
n = The number of times interest is compounded annually.
t = Number of years
Present Value Formula:
The present value (PV) is the current worth of a future sum of money, considering a specific interest rate and time period. The formula for present value is:
PV = FV / (1 + r)^t
Where:
PV = Present Value
FV = Future Value
r = Discount rate or interest rate (expressed as a decimal)
t = Number of years
Return on Investment (ROI) Formula
ROI is a measure of the profitability of an investment and is expressed as a percentage. The formula for ROI is:
((Current Value – Initial Investment) / Initial Investment) * 100 = ROI
Debt-to-Equity Ratio Formula
The debt-to-equity ratio assesses a company’s financial leverage by comparing its total liabilities to shareholders’ equity. The formula is:
Total Debt / Shareholders’ Equity = Debt-to-Equity Ratio
Net Present Value (NPV) Formula
NPV helps determine the profitability of an investment by comparing the present value of expected cash inflows to the present value of cash outflows. The formula for NPV is:
NPV = Σ [CFt / (1 + r)^t] – Initial Investment
Where:
Σ = Summation sign
CFt = Cash flow in a specific time period t
r = Discount rate or capital cost
t = Time period
Conclusion:
Finance is a vast field with numerous concepts, tools, and formulas that aid in making informed financial decisions. By understanding the fundamentals of finance and familiarizing yourself with essential formulas like compound interest, present value, ROI, debt-to-equity ratio, and NPV, you can effectively manage personal finances or make sound business choices. Remember that seeking professional advice is crucial, especially for complex financial matters, to ensure your long-term financial success.
