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. Each uses conservative industry benchmarks — the estimates are designed to be defensible in a board meeting, not to inflate the number.
1. OTB accuracy lift
Industry average OTB accuracy is 65–78%. Every 1pp improvement in accuracy reduces stockout-driven lost sales by approximately 0.25%. The calculator closes the gap from your current accuracy toward an 85% benchmark (capped at 12pp improvement). Revenue lift = gap closed × 0.0025 × net sales.
2. Markdown margin recovery
The floor benchmark for markdown rate is 12% (efficient, well-planned brands). The calculator models a maximum 4pp reduction from your current rate toward this floor. Margin recovery = reduction pp × net sales × gross margin %.
3. Planning time savings
Planners at spreadsheet-dependent brands spend approximately 50% of their time on data maintenance. The calculator models a 40% reduction in maintenance time (consistent with connected planning implementations), applied to fully-loaded salary cost.
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 uses deliberately conservative assumptions: a 12pp OTB accuracy improvement (not the full gap to benchmark), a maximum 4pp markdown rate reduction, and a 40% planning cycle reduction. Many brands see higher improvements. The intent is to provide 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 calculator estimates that each 1pp improvement in OTB accuracy drives approximately 0.25% incremental revenue — from better timing and fewer stockouts.
How is the markdown margin recovery calculated?
The calculator estimates how much gross margin is recovered by reducing your markdown rate toward a 12% benchmark floor. For 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. This is the margin dollars that were previously given away through markdowns you could have avoided with a better-planned receipt flow.
What counts as planning time savings?
Planners at brands without connected systems typically spend 40–60% of their time on data gathering, spreadsheet maintenance, and manual consolidation — not analysis. The calculator assumes 50% is maintenance, a 40% reduction in that time, and converts the freed capacity to dollar value at the average fully-loaded salary entered. This time can be redirected to analysis, scenario planning, and cross-functional alignment.
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.
