How to Calculate the ROI of a Shopify Redesign

Shopify redesign ROI compares the financial benefit attributable to a redesign with the cost of delivering it. Calculate it over a defined period, such as six or twelve months, and use profit contribution rather than revenue alone.

Return on investment expresses the net return relative to the investment:

Redesign ROI (%) = [(Incremental contribution profit + Operating savings − Total redesign costs) ÷ Total redesign costs] × 100

For this calculation:

• Incremental contribution profit is additional revenue attributable to the redesign, less the variable costs of generating and fulfilling those sales.
• Operating savings are verified reductions in existing expenses, such as discontinued software subscriptions.
• Total redesign costs include design, development, content, migration, testing, internal project work and additional ongoing expenses within the measurement period.

Count each expense or saving once. For example, if replacement software fees are deducted when calculating net app savings, do not also include them in project costs.

1. Revenue Lift from Conversion Rate Improvements

To estimate the effect of conversion changes alone, hold traffic and average order value constant:

Estimated additional revenue = Sessions × (New conversion rate − Baseline conversion rate) × Baseline AOV

Use conversion rates as decimals. For example, with 50,000 monthly sessions, an $80 average order value and conversion increasing from 2% to 2.2%:

50,000 × (0.022 − 0.020) × $80 = $8,000 in additional monthly revenue

That change is a 0.2 percentage-point increase, or a 10% relative improvement.

This is an illustrative estimate, not a promised result. At a 40% contribution margin, the additional revenue would contribute $3,200 before redesign costs and any additional operating expenses.

2. Revenue Lift from Increased Traffic

Estimate the effect of additional qualified traffic using:

Estimated additional revenue = Additional sessions × Expected conversion rate × Expected AOV

Use conversion and order-value assumptions appropriate to the traffic source. New organic visitors may behave differently from returning customers or paid campaign traffic.

Do not attribute every post-launch traffic increase to the redesign. Account for advertising changes, seasonality, promotions and other content work. A redesigned store does not automatically receive more organic traffic.

3. Revenue Lift from Higher Average Order Value

To isolate the effect of average order value, hold order volume constant:

Estimated additional revenue = Baseline orders × (New AOV − Baseline AOV)

Evaluate the margin on those larger orders. Discounts, additional shipping costs or a shift toward lower-margin products can reduce the benefit of higher AOV.

When traffic, conversion and AOV change together, calculate the combined revenue difference:

Estimated revenue lift = (New sessions × New conversion rate × New AOV) − (Baseline sessions × Baseline conversion rate × Baseline AOV)

Use this combined result instead of adding overlapping estimates from separate calculations. It captures the interaction between the three variables once. It still requires evidence to determine how much of the difference is attributable to the redesign.

4. Savings from App & Maintenance Changes

Compare actual costs before and after the project. Include app subscriptions, usage charges, maintenance retainers and replacement tools.

Our Shopify app audit guide explains how to assess overlapping functionality and check removal dependencies.

Only count savings when the expense ends or decreases. Annual commitments, migration work and replacement functionality can delay or offset the benefit.

Track staff time saved separately unless it produces a documented financial benefit, such as reduced contractor spending. There is no universal number of apps a redesign should remove or a fixed monthly saving every store can expect.

Step-by-Step: How to Calculate Shopify Redesign ROI

Step 1: Establish Your Baseline & Measurement Period

Record the metrics needed to model revenue, costs and customer behavior:

• Online store sessions and conversion rate.
• Orders and average order value.
• Discounts, refunds and returns.
• Contribution margin and variable fulfillment costs.
• Marketing spend and traffic sources.
• App and maintenance expenses.
• Add-to-cart and checkout completion rates.

Keep sales channels, reporting definitions and date ranges consistent. Segment by device and traffic source where useful, and document promotions or stockouts that affected the baseline.

Choose a period long enough to reflect your buying cycle and normal fluctuations. Preserve tracking through the redesign so apparent improvements do not simply reflect changed measurement.

Step 2: Build Downside, Base & Upside Scenarios

Use store-specific evidence to estimate outcomes: usability findings, previous experiments, observed performance problems and confirmed software savings.

Create three scenarios:

ScenarioWhat to modelDownsideNo improvement or a temporary decline, with potential delays or additional costsBaseModest changes supported by your strongest evidenceUpsideLarger improvements that remain plausible but less certain

Document the reason for each assumption. Avoid presenting unsupported percentage ranges as industry averages.

Also estimate what would happen without the redesign. This provides a more useful comparison than assuming the business would otherwise remain unchanged.

Step 3: Calculate ROI for the Selected Period

The following is a hypothetical six-month example, continuing the conversion scenario above. It assumes the improvement lasts throughout the period and is attributable to the redesign.

ItemSix-month amountAdditional revenue$48,000Contribution profit at a 40% margin$19,200Verified operating savings$1,800One-time redesign costs$15,000Additional ongoing project expenses$3,000Total redesign costs$18,000Net financial benefit after project costs$3,000

Six-month ROI = [($19,200 + $1,800 − $18,000) ÷ $18,000] × 100 = 16.7%

This calculation shows why revenue lift alone overstates the return: part of each additional sale pays for products, fulfillment and other variable expenses.

After launch, replace projections with measured results. Where feasible, use controlled tests to assess causation; a simple before-and-after comparison cannot isolate the redesign from every other business change.

Step 4: Track Payback & Longer-Term Results

Payback occurs when cumulative incremental contribution profit and operating savings, after additional ongoing expenses, cover the initial investment.

Track this month by month. Allow for launch disruption, uneven sales and maintenance costs rather than assuming the first month’s result continues indefinitely.

Longer-term benefits may include repeat purchases, lower support costs or more efficient content updates. Include them when you have evidence, and avoid counting repeat-order revenue again if it is already included in the sales model.

Report the measurement period alongside every ROI figure. A six-month return and a two-year return describe different outcomes, and a redesign’s benefits do not automatically compound over time.
