Perpetuity Calculator - Infinite Cash Flow Value

A perpetuity is a stream of payments expected to continue without a scheduled end. The calculation provides a compact present-value estimate for fixed dividend policies, endowments, long-lived income rights, and simplified valuation models. The calculator uses the displayed inputs and formula to produce a transparent estimate. Level perpetuity value = payment ÷ periodic discount rate. Growing perpetuity value = payment ÷ (periodic discount rate − periodic growth rate). The result is most useful when every input refers to the same period, currency, and definition. Enter values from a current statement, quote, market source, or scenario assumption rather than relying on a remembered approximation. Recalculate whenever an important rate, date, balance, fee, or underlying condition changes. Use the result to compare realistic alternatives, not to reduce a financial choice to a single figure. Change one assumption at a time and note how the outcome responds. That approach makes it easier to distinguish a change caused by price, rate, timing, allocation, or an operating assumption. The worked examples illustrate the calculation mechanics, but your own situation may use different terms, taxes, fees, contract rules, or market conditions. Financial estimates are not promises of a future outcome. Providers may use their own pricing schedules, rounding rules, payment dates, eligibility checks, or legal definitions. Investment and economic measures also depend on uncertain inputs and can change quickly. Treat this tool as an educational planning aid and verify critical figures against official documents, current program terms, a lender disclosure, processor schedule, court order, or other authoritative source. A careful review also considers factors outside the formula. Cash-flow capacity, risk tolerance, taxes, liquidity, penalties, required insurance, and alternative uses of money can matter as much as the calculated output. Save the assumptions with the result when comparing options, then revisit the scenario before making a commitment. This calculator provides a repeatable starting point for that conversation and helps make the arithmetic clear.
