Formula Used
1) Net Successful Upgrades
Net Successful Upgrades = Successful Upgrades − Refunded Upgrades
2) Upgrade Rates
Visitor Upgrade Rate = Net Successful Upgrades ÷ Visitors Exposed × 100
Eligible Upgrade Rate = Net Successful Upgrades ÷ Eligible Users × 100
Click to Upgrade Rate = Net Successful Upgrades ÷ Upgrade Clicks × 100
3) Gross Incremental Revenue
Gross Incremental Revenue = Net Successful Upgrades × Retention Rate × (Upgraded Price − Current Price) × Billing Cycles
4) Net Incremental Revenue
Net Incremental Revenue = Gross Incremental Revenue − Discount Cost − Payment Fees − Variable Service Cost
5) Contribution Per Upgrade
Contribution Per Upgrade = Revenue Per Upgrade − Discount − Fees − Service Cost
6) Break Even Upgrades
Break Even Upgrades = Campaign Cost ÷ Contribution Per Upgrade

Frequently Asked Questions
1) What does this calculator measure?
It measures how efficiently users move from exposure to a paid upgrade. It also estimates retained revenue, cost per upgrade, contribution per upgrade, benchmark lift, and break-even volume.
2) Why is the eligible user rate important?
Eligible user rate isolates the people who could realistically upgrade. That makes campaign comparisons cleaner because it removes unqualified traffic and focuses on offer quality.
3) Should refunded upgrades be subtracted?
Yes. Refunds, reversals, and short-lived plan switches can overstate success. Removing them gives you a more trustworthy conversion rate and a more realistic revenue estimate.
4) How does retention affect revenue?
Retention scales the number of upgrades that stay active across the selected billing cycles. Lower retention reduces expected revenue and can quickly change a campaign from profitable to weak.
5) What benchmark should I enter?
Use your own historical eligible upgrade rate, a segment-specific target, or a controlled test baseline. The benchmark works best when it comes from similar audiences and pricing conditions.
6) Can this calculator handle annual plans?
Yes. Treat the prices as annual values and set billing cycles to the number of annual renewal periods you want to model. Keep the cost assumptions aligned with that horizon.
7) Why can conversion improve while revenue falls?
A campaign can create more upgrades but still lose money if discounts are deep, retention is weak, payment fees are high, or the price increase between plans is small.
8) What is a healthy upgrade result?
A healthy result usually beats your benchmark, generates positive net incremental revenue, and requires fewer break-even upgrades than you actually achieved. Healthy means scalable economics, not just a higher percentage.
