The direct answer
A cell tower lease buyout scenario discounts future lease income to a present value, using stated growth, timing and discount assumptions. Contract rights, counterparty risk and transaction terms can make an actual offer differ from the arithmetic value.
Map the cash flows you are valuing
Identify the first-year lease payment, escalation and modeled horizon. The calculator assumes first payment at the end of year one, with growth beginning in year two. It does not assess renewal rights, early termination, assignment restrictions or other lease provisions. Those terms can change the cash flows available to the owner and need review before entering a simplified schedule.

Discount consistently and test the rates
The growing-annuity relationship values the selected income stream at the chosen discount rate. If growth equals the discount rate, the calculation uses a mathematical limit rather than dividing by zero. A lower discount rate raises present value for the same positive payments. The rate is a scenario input, not a market quotation or a measure automatically derived from contract risk.
Keep terminal value explicit
The linked model adds a terminal value only when the user enters one. It does not infer a sale multiple, perpetual income or a guaranteed renewal beyond the horizon. Gross present value is also different from after-tax or after-transaction-cost proceeds. Compare the scope of an actual buyout offer with the income rights modeled here instead of treating the tool as a contract recommendation.
Worked example
For a small timing illustration, $1,000 at year one and $1,020 at year two discounted at 8% have a combined PV of $1,800.41. The linked default $36,000 first-year lease, 2% growth, 15 years and 8% discount rate produces about $345,435.70 before any terminal value.

Common mistakes and limitations
Do not assume that all scheduled payments are guaranteed or that the lease continues after the modeled horizon. Avoid adding an exit multiple unless its basis is explicitly defined.
Scenario valuation only. Renewal probability, easement rights, taxes, legal terms and tower-company credit are not modeled automatically.
Frequently asked questions
What if growth and discount rates are equal?
The tool uses the growing-annuity limit, so the present value remains defined for the valid scenario.
Does the indicated PV determine an acceptable offer?
No. It values the supplied cash schedule and does not evaluate all contract, risk, tax or transaction terms.
