Write the proposed rent formula in plain language
A lower base rent can be attractive when opening a store, particularly if sales are uncertain. A percentage-rent clause may transfer part of that uncertainty into a higher payment once trading improves. Comparing only the minimum monthly rent misses the commercial trade-off. Finance needs to evaluate the actual formula across the sales levels the store could reasonably achieve.
Obtain the complete proposal and ask the lease adviser to confirm the base rent, percentage rate, sales breakpoint, measurement period and definition of eligible sales. Determine whether percentage rent is additional to base rent or whether the agreement uses another structure. A phrase such as eight percent rent is insufficient to build a dependable model.
A publicly filed 2023 San Marcos Premium Outlets lease illustrates the detail involved: it separately specifies minimum rent, percentage rent on adjusted sales above a breakpoint, partial-year adjustments and reporting obligations. It is an example of negotiated terms, not a standard form or a current price recommendation. Your model should follow the proposal being considered.

Calculate the threshold without inventing one
Consider an invented lease with $120,000 annual base rent plus 8% of eligible annual sales above $1.5 million. At $1.2 million of eligible sales, there is no percentage rent and total base-plus-percentage rent remains $120,000. At $1.8 million, the excess is $300,000, generating $24,000 additional rent and a $144,000 total.
At $2.5 million of eligible sales, the excess over the same breakpoint is $1 million. Additional rent is $80,000 and total rent is $200,000. Applying 8% to all $2.5 million and then adding the base would produce $320,000, which is not what the assumed clause says.
In this example, $120,000 divided by 8% happens to equal the stated $1.5 million breakpoint. That relationship should not be imposed on every proposal. If the agreed breakpoint were $1 million instead, $1.8 million of eligible sales would produce $64,000 additional rent and $184,000 total. The written breakpoint controls the calculation.
| Eligible annual sales | Base rent | 8% above the stated $1.5 million breakpoint | Total of these two rent components |
|---|---|---|---|
| $1,200,000 | $120,000 | $0 | $120,000 |
| $1,800,000 | $120,000 | $24,000 | $144,000 |
| $2,500,000 | $120,000 | $80,000 | $200,000 |
Compare both proposals at the same trading levels
Suppose a second hypothetical proposal has $100,000 base rent plus 10% of eligible sales above $1 million. Assume for this comparison that both proposals use the same sales definition and cover otherwise equivalent premises and periods. At $800,000 sales, the second costs $100,000 against the first proposal's $120,000.
At $1.2 million sales, the second costs $120,000 and the first also costs $120,000. At $1.8 million, the second costs $180,000 against the first's $144,000. The lower base is valuable in weak trading but does not remain the cheaper arrangement as sales rise. Show the range instead of choosing the proposal that looks best at a single convenient forecast.
Then restore the differences intentionally excluded from that comparison. Location, usable area, fit-out spending, opening date, service charges and customer access may differ. A cheaper formula in an unsuitable site is not a comparable alternative. Explain which benefits and obligations are already reflected in the store's sales and operating plan.
Bridge accounting sales to the lease's sales base
The rent calculation may use a contractual measure that differs from financial-statement revenue or cash deposits. Ask the lease adviser to resolve the treatment of refunds, taxes, delivery charges, gift cards and sales through connected channels. Finance should then identify the source data needed to implement that interpretation.
Pay particular attention to orders placed online but collected, fulfilled or assisted in the store. The commercial effect depends on the actual attribution terms. Do not exclude all online sales merely because a payment processor labels them ecommerce, or include them all because staff helped with delivery. The model needs the agreed population.
A change in channel mix can therefore change percentage rent even when total company sales are stable. Prepare a bridge from the proposed store forecast to the eligible lease base, with each material inclusion or exclusion shown. If the business cannot currently produce that information, include the cost and responsibility for reliable reporting in the proposal evaluation.
Forecast rent when cash actually becomes payable
Check whether the lease year matches the calendar year and how an opening partway through a year changes the breakpoint. A seasonal retailer cannot safely divide every annual amount by twelve without reading the terms. Some formulas depend on cumulative sales crossing a threshold, while others call for interim calculations and later reconciliation.
Place the expected payments on the store's cash calendar, alongside inventory purchases and customer receipts. The month with the strongest sales may also generate a later rent payment. Keep the annual cost calculation connected to that payment schedule so that a year-end cash surplus does not conceal an obligation already earned under the lease.
Review later years separately. Base rent and breakpoints may change on different schedules, and concessions may end. Ask whether the proposed model follows each year's actual terms rather than extending the first-year formula indefinitely. Accounting recognition should be reviewed under the applicable reporting framework; this commercial comparison does not establish the lease accounting entries.
Use contribution after variable rent to judge growth
Once sales exceed a breakpoint, additional eligible sales can create an additional rent cost. Reflect that cost when evaluating a promotion or channel expansion at the location. Under the first hypothetical formula, an extra $100,000 of eligible sales entirely above the breakpoint adds $8,000 of rent, before considering the promotion's other costs and contribution.
That does not mean extra sales are undesirable. It means their value should be measured after the payments they cause. ACCA's relevant-cost analysis provides the underlying discipline: identify the future cash flows changed by the decision. Avoid using the average rent percentage from a lower sales level when the next sales increment falls above the threshold.
Present the lease decision with the tested sales range, complete occupancy-cost assumptions, reporting requirements and lowest forecast cash balance. Name unresolved contract interpretations before approval. A useful comparison shows both what the business commits to in weak trading and what it shares with the landlord when the store performs well.
