Enter your total fixed costs (e.g. rent, salaries, overhead).
Cost per unit that scales with volume (materials, direct labour, etc.).
Selling price per unit.
Break-even units = Fixed costs / (Price − Variable cost per unit)Upfront investment amount (use a positive number).
Expected constant annual net cash inflow.
Payback period = Initial investment / Annual cash flow.Upfront investment amount (capital you put in).
Final value or amount received (including payback of principal).
ROI = (Final value − Initial investment) / Initial investment.Enter an initial investment at t=0 and up to five annual cash flows. The initial investment will be treated as an outflow (negative).
IRR is the discount rate r such that NPV(r) = 0. Simple bisection search between -90% and +100%.Enter the discount rate used to discount future cash flows.
How much you invest today (enter as a positive number).
Expected annual net cash inflow generated by the investment.
Number of years until the investment begins generating cash flows.
Total economic lifetime of the investment (in years).
This calculator supports NPV, equivalent annual value, useful-life decisions, and timing of commissioning.Estimate how your investment grows with compound interest and regular contributions.
Uses monthly compounding. Regular contributions are assumed monthly at the end of each period.Total loan amount (principal borrowed).
Annual interest rate on the loan.
Loan term in years (used if no monthly principal is entered).
Optional: fixed monthly principal repayment amount.
Enter the total return generated by the company’s assets.
Interest rate applied to the company's debt capital.
Amount of equity invested by shareholders.
Total amount of borrowed capital.
Formula: rE = rG + (rG − i) · D/EEnter the nominal interest rate before adjusting for inflation.
Enter the inflation rate used to convert nominal to real interest.
Formula: ireal = (1 + inom) / (1 + π) − 1Define the lower bound for the discount rate range.
Define the upper bound for the discount rate range.
Choose how much the rate increases between rows in the table.
Enter the initial investment amount (today, as a positive number).
Expected constant annual net cash inflow.
Number of years until the investment starts generating cash flows.
Total economic lifetime of the investment (in years).
Enter up to three scenarios with their NPVs and probabilities to calculate expected NPV and risk metrics.
Best-case scenario with highest expected return.
Scenario 1Most realistic or average expected outcome.
Scenario 2Worst-case scenario for downside risk assessment.
Scenario 3Enter your total investment budget and up to four projects. The tool will select the combination with the highest total NPV that stays within the budget.
Maximum amount you are allowed to invest across all projects.
First project you are considering.
Project 1Second project you are considering.
Project 2Third project you are considering.
Project 3Fourth project you are considering.
Project 4Estimate the Baldwin interest rate as a risk-adjusted comparison rate based on present worth and equivalent annual worth.
Optional: base comparison interest rate (e.g. WACC, discount rate) to show the spread.
Simplified definition: Baldwin interest rate ≈ EAW / PW (per year). Use when PW and EAW already reflect depreciation, replacements, maintenance and salvage effects.Compute the weighted average cost of capital (WACC) based on the mix of equity, debt, and tax rate.
Corporate tax rate to adjust the cost of debt (optional, defaults to 0% if left empty).
Formula: WACC = (E / (D + E)) × Re + (D / (D + E)) × Rd × (1 − T).
