Decision Analysis
Should I Sign This Lease?
A commercial lease is one of the largest fixed commitments a business makes. You are locked in for years regardless of how revenue performs. Incertive helps you understand whether the location pencils out across the range of realistic scenarios - not just the optimistic one.
The Lease Commitment Problem
A three-year commercial lease at $5,000 per month is a $180,000 commitment. A five-year lease at $8,000 per month is $480,000. These are not expenses you can turn off if business slows down. Unlike inventory you can discount or staff you can reduce, lease payments are fixed obligations that continue whether you have customers or not.
The decision to sign a lease typically hinges on a revenue projection. You estimate how much business the location will generate, subtract the rent and operating costs, and determine whether the location is profitable. But that projection is built on assumptions about foot traffic, conversion rates, average transaction size, and market conditions - all of which are uncertain. The question is not whether the location could be profitable, but how likely it is to be profitable under realistic conditions.
This is compounded by the asymmetry of the commitment. If the location does well, you benefit from the fixed cost - revenue grows while rent stays the same. If the location underperforms, you are trapped paying for space that does not generate enough revenue to cover its cost. Breaking a lease early usually means paying several months of remaining rent as a penalty, plus the cost of relocating. The downside is often more damaging than the upside is beneficial, which is why understanding the probability distribution of outcomes matters so much for lease decisions.
Key Uncertainties in a Lease Decision
Foot traffic and customer volume
The number of potential customers who pass by or visit your location varies by day, season, and year. New construction, road changes, competing businesses, and neighborhood development all affect traffic patterns in ways that are difficult to predict precisely.
Revenue ramp-up timing
A new location rarely reaches its full revenue potential immediately. It takes time for customers to discover you, for word of mouth to build, and for operations to stabilize. The ramp-up period could be 3 months or 12 months - and during that time, you are paying full rent.
Operating cost variability
Beyond rent, a location has utilities, maintenance, insurance, staffing, and other operating costs that fluctuate. Triple net leases add property tax and maintenance uncertainty on top of base rent. Total occupancy cost is rarely what you expect on day one.
Market and competitive changes
A competitor could open nearby. The neighborhood could change. A major employer could move in or out of the area. Economic downturns could reduce consumer spending. These external factors affect your revenue but are outside your control.
Break-even timeline
How long until the location covers its costs? The break-even point depends on all the other uncertainties - and it is the most important number for your cash flow planning. If break-even takes twice as long as expected, you need twice the cash reserves to survive the ramp.
How It Works With Incertive
You describe the lease decision in plain language. For example:
Incertive identifies the uncertain variables - foot traffic, conversion rate, ramp time, revenue range - and runs Monte Carlo simulation across thousands of scenarios. The output includes:
Interpreting the Results
The simulation might show that there is a 74% probability of the location being cash-flow positive within 12 months, but a 12% probability of still being cash-flow negative at 18 months. It might reveal that you need $80,000 to $110,000 in total capital - not just the build-out cost, but enough to cover the ramp period when rent exceeds revenue.
The sensitivity analysis might show that the ramp-up period is the single most important variable. A 3-month ramp versus an 8-month ramp is the difference between a profitable first year and a cash crisis. This insight directs your strategy: invest heavily in pre-opening marketing, negotiate a rent abatement for the first few months, or choose a location with established foot traffic rather than an up-and-coming area.
Plan variants might reveal that a 5-year lease at $5,500/month outperforms the 3-year lease at $6,200/month in most scenarios - even accounting for the longer commitment - because the lower monthly cost gives you more runway during the ramp. This is the kind of insight that comes from probabilistic go/no-go analysis and is nearly impossible to see in a simple spreadsheet comparison.
Frequently Asked Questions
How does Incertive help evaluate a commercial lease?
Incertive models the financial impact of a lease under uncertain conditions - revenue variability, foot traffic uncertainty, operating cost fluctuations, and the possibility that you might need to break the lease early. Instead of comparing lease options based on a single revenue projection, you see how each option performs across thousands of scenarios. This shows you the probability of the lease being affordable under different business conditions.
What lease terms can I compare using Incertive?
You can compare any combination of lease structures: shorter terms at higher monthly rates versus longer commitments at lower rates, triple net versus gross leases, leases with escalation clauses, options to renew, early termination penalties, and tenant improvement allowances. Each option gets modeled against your revenue uncertainty so you see which structure performs best across the range of likely outcomes.
Can Incertive model the risk of needing to break a lease?
Yes. If there is a possibility that business conditions could deteriorate enough to make the location unviable, Incertive models that scenario along with the financial impact of early termination - penalties, remaining obligations, and the cost of relocation. You see the probability of needing to exit and the total cost under those scenarios.
How does foot traffic uncertainty factor into the analysis?
Foot traffic is one of the key variables for retail and restaurant leases. You describe the range you expect - "500 to 1,200 people passing the location per day" - along with your conversion rate uncertainty. Incertive models how foot traffic variability translates into revenue variability, which directly affects whether the lease payments are sustainable.
Should I use Incertive before or after negotiating lease terms?
Both. Before negotiation, Incertive helps you understand which terms matter most for your specific situation - maybe the monthly rate matters less than the early termination clause, or maybe a tenant improvement allowance is worth more than a rent reduction. During negotiation, you can re-run the analysis with proposed terms to see how each counteroffer changes your risk profile.
