Frequently Asked Questions
Plug in your dividend and discount rate — our perpetuity calculator reveals the lump sum behind your passive income. Rethink your savings plan today.
A: A perpetuity calculator computes the present value (PV) of an infinite stream of equal cash flows. It uses the formula PV = Dividend ÷ Discount Rate. Enter your annual cash flow and discount rate — the tool returns your result instantly.
A: Use the formula: Present Value = Annual Cash Flow ÷ Discount Rate. Example: a $10,000 annual dividend at a 12% discount rate equals a present value of $83,333.33. Our calculator handles this in one click.
A: It depends on your context. Investors typically use the expected rate of return or weighted average cost of capital (WACC). For personal FIRE planning, a 4%–7% discount rate is common, reflecting long-term market return assumptions.
A: Present value moves inversely with the discount rate. When rates rise, PV falls — and vice versa. A jump from 8% to 12% on a $10,000 dividend drops PV from $125,000 to $83,333. Use the calculator to test different rate scenarios instantly.
A: An annuity pays cash flows for a fixed period. A perpetuity pays forever — no end date. The perpetuity calculator is simpler: no term variable needed. Annuity calculations require both a time horizon and a discount rate.
A: Yes. The 4% Rule — a cornerstone of FIRE (Financial Independence, Retire Early) — is essentially a perpetuity model. Divide your annual expenses by 0.04 to find your target nest egg. Our calculator makes that math immediate and visual.
A: Yes. A growing perpetuity (also called Gordon Growth Model) adds a constant growth rate (g) to the formula: PV = Dividend ÷ (Discount Rate − Growth Rate). If your dividends grow at 3% annually and your discount rate is 10%, the effective rate is just 7%. Look for a calculator that supports the growth rate input for more realistic projections.
A: Mathematically, it is 100% accurate — the formula has no ambiguity. The real variable is your assumed discount rate. Choose it carefully. A 1% difference in rate can shift your present value by tens of thousands of dollars. Run multiple scenarios to stress-test your plan.
