Find the unit volume at which total revenue equals total cost — the threshold beyond which a business starts generating profit.
ROI Calculator
Calculate the percentage return on an investment as (Final Value − Initial Investment) / Initial Investment × 100.
Present Value Calculator
Discount a future cash amount back to today's value using PV = FV / (1 + r)ᵗ.

Compute the periodic payment for a fully amortising fixed-rate loan from the principal, annual interest rate, term in years, and payment frequency.
GDP Per Capita Calculator
Compute Gross Domestic Product per capita by dividing a country's total GDP by its population.

Compute the percentage change between two Consumer Price Index values, the standard measure of inflation between any two time periods.
Profit Margin Calculator
Compute the gross profit margin as a percentage from total revenue and total costs.
Tax Multiplier Calculator
Compute the Keynesian tax multiplier from the marginal propensity to consume (MPC), measuring how a tax change affects total economic output.

Debt-to-GDP Ratio Calculator
Compute a country's or entity's debt-to-GDP ratio to assess fiscal health and borrowing sustainability.
Economic Profit Calculator
Calculate true economic profit by subtracting both explicit and implicit (opportunity) costs from total revenue.
Money Multiplier Calculator
Calculate how much the banking system can expand the money supply from an initial deposit given a reserve ratio.
Gini Coefficient Calculator
Measure income inequality within a population using the Gini coefficient.
Cost-Benefit Ratio Calculator
Determine whether a project or investment is financially worthwhile by comparing total benefits to total costs.
Exchange Rate Impact Calculator

Inflation Impact Calculator
Calculate how much your money's purchasing power will shrink (or has shrunk) over time at a given annual inflation rate, in either direction.

Finds the optimal number of units to order at a time, minimizing combined ordering and inventory-holding costs.
GDP Growth Rate Calculator
Calculate a country's or region's nominal or real GDP growth rate over any time horizon.
Cost-Benefit Analysis Calculator
Evaluate whether a project is financially worthwhile by computing its Net Present Value (NPV) and benefit-cost ratio.
Monopoly Profit Maximization Calculator
Determine the profit-maximizing price and output level for a monopolist facing a linear demand curve.
Net Present Value (NPV) Calculator
Calculates the net present value of a project with uniform annual cash flows and an optional terminal value.
Inflation-Adjusted Return Calculator
Find out what your investment actually earned after inflation erodes purchasing power.
Cost of Living Comparison Calculator
Estimate the salary you'd need in a new city to maintain your current standard of living.
Debt-to-Income Ratio Calculator
Calculate your debt-to-income (DTI) ratio to see how lenders view your borrowing capacity.
