Merchandising ROI Calculator
The Merchandising ROI Calculator quantifies the annual financial value of connected planning for apparel brands — translating OTB accuracy improvements, markdown rate reductions, and planning efficiency gains into dollars, so you can build a credible business case for upgrading your planning infrastructure.
OTB Accuracy Lift
Revenue captured from fewer stockouts and better receipt timing
Markdown Recovery
Gross margin reclaimed from reducing avoidable markdown spend
Time Savings Value
Planner capacity freed from spreadsheet maintenance

How the ROI is calculated
The calculator models three value drivers independently and sums them. Every figure below is a stated model assumption — there is no survey behind these numbers — chosen so the estimate reads as a floor, not a ceiling. Where your own data disagrees with an assumption, trust your data.
1. OTB accuracy lift
The model assumes an 85% OTB accuracy reference point and closes the gap from your current accuracy toward it, capped at a 12pp improvement. It further assumes each 1pp of accuracy improvement recovers approximately 0.25% of net sales from stockout-driven lost sales. Revenue lift = gap closed × 0.0025 × net sales. Both figures are model assumptions, not industry averages.
2. Markdown margin recovery
The model assumes a 12% markdown-rate floor and models a maximum 4pp reduction from your current rate toward it. Margin recovery = reduction pp × net sales × gross margin %. The floor is a model assumption, not a published benchmark.
3. Planning time savings
The model assumes 50% of planner time goes to data maintenance and models a 40% reduction in that maintenance time, applied to fully-loaded salary cost. Both are model assumptions — if your team's split differs, scale the output accordingly.
Frequently asked questions
What does this calculator measure?
The Merchandising ROI Calculator estimates the annual financial value of improving three specific planning capabilities: OTB accuracy (which drives revenue capture), markdown rate reduction (which recovers gross margin), and planning cycle efficiency (which frees planner time for higher-value analysis). It generates a total annual ROI estimate, a 3-year cumulative value, a payback period, and an ROI multiple.
How conservative are the estimates?
The calculator caps each driver by assumption: a maximum 12pp OTB accuracy improvement, a maximum 4pp markdown rate reduction, and a 40% planning cycle reduction. These caps are stated model assumptions, not measured industry statistics — chosen so the output reads as a credible floor, not a best-case ceiling.
What is OTB accuracy and how does improving it drive revenue?
OTB accuracy measures how closely your planned receipts match what you actually land, when you planned to land them. Poor OTB accuracy means stockouts at peak demand (lost revenue) and overbuy at the wrong time (markdown spend). The model assumes each 1pp improvement in OTB accuracy drives approximately 0.25% incremental revenue from better timing and fewer stockouts — a stated model assumption, not a measured industry figure.
How is the markdown margin recovery calculated?
The model assumes a 12% markdown-rate floor as its reference point and models a maximum 4pp reduction from your current rate toward it. Worked example: if your current markdown rate is 18%, reducing it by 4pp to 14% on $8M revenue with a 52% gross margin recovers approximately $166K in gross margin annually. The floor is a model assumption, not a published benchmark — the example just shows the arithmetic.
What counts as planning time savings?
The model assumes 50% of planner time goes to data gathering, spreadsheet maintenance, and manual consolidation, models a 40% reduction in that time, and converts the freed capacity to dollar value at the average fully-loaded salary you enter. Both figures are model assumptions. The closest published reference point: a 2018 McKinsey survey of more than 30 retailers found merchants spent approximately two-thirds of their time gathering data, managing exceptions, firefighting, and participating in meetings to syndicate with colleagues — measured on merchants at retailers generally, not on apparel planners specifically.
Is this a RetailNorthstar cost-benefit calculator?
The calculator uses a generic $36K/year planning software cost estimate for payback calculation — it is not RetailNorthstar pricing. Actual pricing depends on team size and modules. The calculator is designed to help you build a business case for connected planning in general, not to justify a specific purchase. If your results suggest significant ROI, we are happy to show you how RetailNorthstar achieves those improvements.
