Formulas
Insurance Premium = Total Insured Value x Risk Rate
Where 'Insurance Premium' is the amount paid (in money), 'Total Insured Value' is the total value of the asset being insured, and 'Risk Rate' is the insurance rate applicable (in percentage). This formula calculates how much an entity needs to pay to cover the risk of loss.
Earnings Before Interest and Tax (EBIT) = Sales - Expenses
Where 'Sales' is the total revenue generated before deductions and 'Expenses' refer to all costs associated with the operation. EBIT provides a look at profitability from core operations excluding the effects of capital structure.
Return on Investment (ROI) = (Net Profit / Cost of Investment) x 100
ROI measures the gain or loss generated relative to the investment cost. A high ROI indicates efficient investment, useful for comparing profitability across different businesses.
Compensatory Rate = Insured Amount / Number of Premium Payments
Where 'Insured Amount' is the total payout in case of a claim and 'Number of Premium Payments' is the total contributions made. This calculates the average risk taken per payment.
Break-even Point (BEP) = Fixed Costs / (Selling Price per Unit - Variable Cost per Unit)
The BEP tells how many units must be sold to cover fixed and variable costs. Useful for assessing profitability and pricing strategies.
Net Present Value (NPV) = Σ (Cash inflow / (1+r)^t) - Initial Investment
Where 'r' is the discount rate and 't' is the time period in years. NPV assesses the profitability of an investment by considering the present value of expected future cash inflows.
Debt-to-Equity Ratio = Total Liabilities / Shareholder's Equity
This ratio indicates what proportion of equity and debt is used to finance a company's assets, highlighting financial leverage and risks.
Annual Percentage Rate (APR) = (Interest / Principal) x (365 / Number of Days)
APR defines the yearly interest generated by a sum charged on a loan or earned on an investment, making it easier to compare different financing options.
Current Ratio = Current Assets / Current Liabilities
This liquidity ratio indicates a company’s ability to pay short-term obligations; a ratio above 1 suggests good short-term financial health.
Operating Expense Ratio (OER) = Operating Expenses / Gross Revenue
OER indicates the efficiency of the company in controlling expenses relative to revenue generated. A lower ratio is better indicative of operational efficiency.
Equations
Total Insurance Claims = (Claim Amount + Out-of-Pocket Expenses)
Calculates total claims an insurer needs to settle by adding both direct claim payouts and any additional expenses incurred by the insured.
Future Value = Present Value x (1 + r)^n
Where 'r' is the interest rate and 'n' is the number of periods. This formula shows how much an amount will grow over time at a specific interest rate.
Cash Flow = Cash Inflows - Cash Outflows
Cash Flow reflects the net amount of cash moving into and out of a company which is vital for maintaining operations, paying bills, and investing.
Gross Profit = Revenue - Cost of Goods Sold (COGS)
The gross profit shows the efficiency of a company in managing its production or labor costs associated with producing its products.
Loan Payment = [Principal x (r(1+r)^n)] / [(1+r)^n - 1]
This equation calculates the monthly payments needed to pay off a loan, incorporating principal, interest, and number of payments.
Cost-Volume-Profit (CVP) Analysis: Contribution Margin = Selling Price - Variable Cost
The contribution margin shows how much revenue is left over after variable costs to cover fixed costs. Useful for decision-making.
Total Revenue = Quantity Sold x Price per Unit
This equation shows total sales revenue generated from selling a specific quantity of goods or services at a set price.
Depreciation Expense = (Cost of Asset - Salvage Value) / Useful Life
Calculates the annual depreciation expense of an asset based on its cost, expected salvage value, and lifespan.
Account Receivables Turnover Ratio = Net Credit Sales / Average Accounts Receivable
This ratio measures how efficiently a business manages its account receivables by showing how many times accounts are collected in a period.
Employee Turnover Rate = (Number of Employees Leaving / Average Number of Employees) x 100
This percentage shows how many employees leave the organization over a specific period, important for assessing HR strategies.
