Corporate Finance Calculators

Corporate finance answers three questions: which investments to make, how to finance them, and what the business is worth. These calculators cover capital budgeting, the cost of capital, valuation, debt capacity and the ratios lenders and investors use to judge financial health.

The calculations follow standard practice and match Excel’s financial functions wherever an equivalent exists, so results can be reconciled to your own models.

The 15 calculators

NPV & IRR Calculator

Evaluate a capital project or investment: net present value, internal rate of return, modified IRR, profitability index, and simple and discounted payback.

WACC Calculator

Estimate the weighted average cost of capital using market-value weights, a CAPM cost of equity and an after-tax cost of debt.

Loan Amortization Schedule

Calculate the periodic payment on a fully amortizing loan, build the schedule, and measure the effect of extra principal payments.

Financial Ratio Analyzer

Enter key balance sheet and income statement lines to calculate liquidity, leverage, efficiency and profitability ratios in one view.

DCF Valuation Calculator

Value a business by discounting projected free cash flow to the firm and a Gordon-growth terminal value at the weighted average cost of capital.

Time Value of Money (PV / FV / PMT)

Solve any time-value-of-money problem — future value, present value, payment, number of periods or interest rate — using Excel-compatible conventions.

CAPM Cost of Equity Calculator

Estimate the cost of equity with the capital asset pricing model, using either an equity risk premium or an expected market return, with optional beta relevering and size or company-specific premiums.

Debt Service Coverage Ratio (DSCR) Calculator

Test whether cash flow covers scheduled principal and interest, measure the cushion against a covenant minimum, and size the maximum loan the cash flow can support.

Working Capital & Cash Conversion Cycle

Measure how many days cash is tied up between paying suppliers and collecting from customers, and how much cash each day of improvement would release.

DuPont Analysis (3- and 5-Step)

Break return on equity into the profitability, efficiency and leverage components that drive it, using both the three-step and five-step DuPont models.

Comparable Company Multiples Valuation

Value a company from the trading multiples of comparable peers: EV/EBITDA, P/E and EV/Revenue, with interquartile ranges and a blended value per share.

Lease vs. Buy Analyzer

Compare the after-tax present-value cost of leasing an asset with borrowing to buy it, including depreciation tax shields, maintenance and residual value.

Bond Price & Yield Calculator

Price a fixed-rate bond from its yield, or solve the yield to maturity from its price, and measure current yield, Macaulay and modified duration, convexity and price sensitivity.

Altman Z-Score Calculator

Calculate the Altman Z-Score from five balance sheet and income statement ratios, using the original model for public manufacturers or the Z′ and Z″ variants for private and non-manufacturing companies.

LBO Quick Model

Model a leveraged buyout in minutes: entry valuation and debt, annual EBITDA growth and cash sweep, exit value, and the sponsor’s IRR and multiple of invested capital, with a value-creation bridge.

Choosing the right calculator

  • Evaluating an investment: use the NPV & IRR Calculator with a discount rate from the WACC and CAPM calculators; compare financing options with Lease vs. Buy.
  • Valuing a business: build a DCF valuation, cross-check it with Comparable Company Multiples, and test a sponsor’s perspective with the LBO Quick Model.
  • Assessing debt: size borrowing with the DSCR Calculator and Loan Amortization Schedule, and price fixed-income securities with the Bond Price & Yield Calculator.
  • Diagnosing financial health: combine the Financial Ratio Analyzer, DuPont Analysis, Working Capital & Cash Conversion Cycle and the Altman Z-Score.

Frequently asked questions

What discount rate should I use for NPV?

Use the weighted average cost of capital for projects with the same risk as the overall business. Riskier projects warrant a higher rate. The WACC and CAPM calculators on this site estimate the inputs.

What is the difference between enterprise value and equity value?

Enterprise value is the value of the whole business to all capital providers. Equity value is what belongs to shareholders, equal to enterprise value minus net debt. Valuation multiples must be applied on a consistent basis.

Which ratios do lenders focus on?

Lenders focus on debt service coverage, leverage (debt to EBITDA or debt to capitalization), liquidity measures such as the current ratio and days cash on hand, and interest coverage. Loan agreements define each covenant precisely.
