Business Finance Calculators
Time-value-of-money and financial-statement-analysis calculators. Distinct from the consumer-/finance/ cluster of mortgages and loans.
Business Finance
10Present Value Calculator
PV = FV / (1 + r)^n. The current worth of a future cash flow.
Future Value Calculator
FV = PV × (1 + r)^n. What today's amount grows to over time.
Annuity Payment Calculator
PMT = P · r / (1 − (1+r)^(−n)). Payment that fully amortizes a principal over n periods at rate r.
Perpetuity Value Calculator
V = C / r — present value of an infinite stream of equal cash flows.
NPV (Net Present Value) Calculator
NPV = sum of discounted future cash flows minus initial investment. Positive NPV = accept project.
IRR (Internal Rate of Return) Calculator
IRR = the discount rate that makes NPV = 0. Solved numerically via Newton's method.
Payback Period Calculator
How many years until cumulative cash flows equal the initial investment.
Discounted Payback Period Calculator
Years for discounted cash flows to recoup initial investment. Time-value-aware variant of payback.
MIRR (Modified IRR) Calculator
IRR with explicit reinvestment-rate assumption. Avoids the multiple-IRR problem.
Profitability Index Calculator
PI = (NPV + initial) / initial = PV of future flows / initial investment. >1 = accept.
