Seasonal Adjustment Calculator
Model how seasonal revenue fluctuations affect MCA payments and merchant cash flow across 12 months.
Why Does Seasonality Matter for MCA?
Many businesses experience significant revenue variation across the year. A beachside restaurant may do $85K in July but only $40K in January. If the MCA holdback is set at 15% based on peak-season revenue, the daily payment during off-season consumes a much larger share of available cash. A holdback that represents 15% of July revenue represents 32% of January revenue -- well above the sustainability threshold. Map revenue across all 12 months, find the worst-case month, and set a holdback percentage that the merchant can handle year-round. This prevents the classic mistake of sizing a deal during peak season that crushes the merchant during the slow months.
How to Use This Calculator
Enter 12 months of revenue
Use actual historical data from bank statements. If the merchant is new, use industry seasonal patterns as a proxy. This is the most data-intensive input but produces the most valuable output.
Set the holdback percentage
The proposed holdback from the funder. The calculator tests this against every month's revenue to find the worst-case scenario.
Review the seasonal risk profile
The worst month analysis shows the peak cash flow burden. If the burden exceeds 25% in the worst month, reduce the holdback or reduce the deal size. The recommended holdback ensures sustainability across all 12 months.
Key Concepts
Seasonal Variance
The difference between the highest and lowest revenue months, expressed as a percentage. A variance above 40% indicates a highly seasonal business that requires careful MCA structuring.
Worst-Case Burden
The MCA payment as a percentage of revenue in the lowest-revenue month. This is the stress point -- if the merchant can survive this month, they can survive all months.
Off-Season Default Risk
The elevated probability of default during a merchant's low-revenue period. MCA deals funded during peak season with terms extending into off-season have structurally higher default risk.
Expert Insights
Fund With the Trough, Not the Peak: The cardinal rule of seasonal MCA underwriting: size the deal based on the merchant's worst month, not their average or best month. If a merchant does $40K in January and $85K in July, size the deal as if every month is $40K. The peak months will accelerate repayment. The trough months will not trigger default. Every deal that defaults during off-season was sized using the wrong revenue baseline.
Timing the Advance Strategically: For seasonal businesses, fund at the beginning of peak season. A restaurant funded in May with an 8-month term repays most of the advance during the strong summer months and finishes during a moderate fall. The same restaurant funded in October with an 8-month term must repay through the worst winter months. Same merchant, same deal, dramatically different default probability based on funding timing.
