Conversion Rate Calculator
Calculates the additional monthly revenue you would generate by raising your conversion rate to a target level. Use it to quantify the business case for CRO investments and A/B testing programs.
About this calculator
Conversion rate is the percentage of website visitors who complete a purchase, and even a small improvement compounds into significant revenue at scale. This calculator computes the incremental revenue gain from reaching a target conversion rate. The formula is: Revenue Uplift = (visitors × (targetConversionRate / 100) × averageOrderValue) − (currentConversions × averageOrderValue). The first term calculates the revenue you would earn if all current visitors converted at your target rate. The second term represents your current revenue baseline. The difference is the additional monthly revenue achievable through optimization. This approach isolates the pure conversion rate effect, keeping traffic and order value constant so you can evaluate CRO initiatives independently from acquisition or pricing changes.
How to use
Say your store gets 20,000 monthly visitors, currently converts 400 orders, has a $75 average order value, and you want to target a 3% conversion rate. Step 1 — Target revenue: 20,000 × (3 / 100) × $75 = $45,000. Step 2 — Current revenue: 400 × $75 = $30,000. Step 3 — Uplift: $45,000 − $30,000 = $15,000 per month. A single percentage-point improvement in conversion rate is worth $15,000 in additional monthly revenue without spending a dollar more on traffic.
Frequently asked questions
What is a good ecommerce conversion rate to target for my store?
The average ecommerce conversion rate sits between 1% and 4%, with the top quartile of stores converting at 3–5% and category leaders reaching 6–8%. Your realistic target depends on your traffic source, product category, and average order value — higher-priced items typically convert at lower rates. Rather than chasing an industry benchmark, set your target as a modest improvement over your own baseline (e.g., 0.5–1 percentage point) and use this calculator to quantify the revenue impact of reaching it.
How does average order value affect the impact of conversion rate improvements?
Average order value (AOV) acts as a multiplier on every incremental conversion you generate. If your AOV is $50, each additional conversion is worth $50 in revenue; at $200 AOV, the same conversion is worth four times as much. This means CRO investments have dramatically higher returns for stores with high AOV products, even if the absolute number of additional conversions is small. Stores should consider optimizing AOV (through bundles, upsells, or free shipping thresholds) alongside conversion rate to maximize the combined revenue impact.
Why should I calculate revenue uplift before starting A/B testing?
Running A/B tests requires time, traffic, and often development resources. Before committing to a testing program, you need to know whether the potential upside justifies the investment. This calculator gives you a clear dollar figure for what a specific conversion rate improvement is worth monthly, which helps prioritize which pages or flows to test first. If a 0.5% conversion rate improvement is worth $8,000/month, even a modest test that takes six weeks to reach significance is obviously worthwhile.
