Lease versus own
The question every business owner in leased space eventually asks. Escalating rent on one side; a payment, an owner's costs and an asset you keep on the other. The honest answer is a year number, and sometimes it is never.
- Break-even year
- Cumulative rent against net ownership cost
- Equity built
- Every assumption on screen
Illustrative only. Bollard is a fictional business built as a website demonstration — the figures below are worked examples, not an offer, a quote or a rate sheet.
The answer
—
Rent paid over the horizon
—
Net cost of owning
—
Equity at the horizon
—
Cumulative
Rent against the net cost of ownership
RentOwn, net of equity
The ownership line credits back the equity you would hold if you sold at that year, after selling costs. That is why it can fall below the rent line even while the payments are larger.

Assumptions and limits
What this model does and does not do
Rent escalates annually at the rate you set and the tenant pays the NNN load in both scenarios, because an owner pays those costs too. Owner ops is what an owner carries that a tenant does not — roof, structure, capital repairs, management.
Ownership equity is the property value at that year, less selling costs, less the loan balance. Crediting it back is what makes this a like-for-like comparison rather than a payment comparison.
No tax treatment is modelled — no depreciation, no interest deduction, no capital gains, no 1031 exchange. Those effects are real, they are specific to your situation, and they belong with your accountant rather than in a public calculator.
Appreciation is an assumption, not a forecast, and it can be set negative. If a small change in that one slider flips the answer, the answer was never robust.

Model it, then let someone check it
Calculators answer the arithmetic. What they cannot tell you is whether a lender will believe your net operating income, or which programme your equity actually supports.
