What is the Revenue Gain Wizard?

Think of this as your "show me the money" calculator. Instead of pulling numbers out of thin air, you can use real data to prove how much money your work will make for a client.

Why use it? Because "trust me, you'll make more money" isn't convincing. But "based on your data, you'll make $50,000" with the math to back it up? That sells.

There are 7 different ways to calculate revenue gain, each for different situations. Pick the one that matches your situation best.

1. A/B Testing 🧪 (When You Tested Something)

In Plain English: You tried something new with some customers and compared it to customers who got the old version. Now you want to know: "If I roll this out to everyone, how much money will we make?"

What you need:

• Treatment Revenue: Money made from customers who got the NEW thing
• Control Revenue: Money made from customers who got the OLD thing (for comparison)
• Scale Factor: How many times bigger is your full customer base vs the test?
  Example: Tested 100 people, have 1,000 total → Scale Factor = 10

Real example: You tested a faster checkout button with 1,000 customers who spent $120,000 total. Another 1,000 customers had the old slow checkout and spent $100,000. You have 10,000 total customers.

New checkout made: $120,000
Old checkout made: $100,000
Difference per group: $20,000
Scale up to everyone (×10): $20,000 × 10 = $200,000 extra revenue

2. Difference-in-Differences 📊 (The Smart Comparison)

In Plain English: You changed something for Group A but not Group B. Both groups' sales went up (maybe the economy is good?). But Group A went up MORE. That extra "more" is what YOUR work did.

What you need:

• Treated Group - Before: What Group A made BEFORE you changed anything
• Treated Group - After: What Group A made AFTER your change
• Control Group - Before: What Group B made BEFORE (they didn't get the change)
• Control Group - After: What Group B made AFTER (still no change)

Real example: You improved Product A's listing. Product B stayed the same. The whole market is growing, so both went up. But Product A went up MORE because of your work.

Product A: $500k → $620k (up $120k) ✨ your improvement
Product B: $480k → $504k (up $24k) 📈 market growth
Your impact: $120k - $24k = $96,000
(This filters out "it just happened anyway" from "you actually did this")

3. Funnel Optimization 🎯 (More Visitors Buy Stuff)

In Plain English: You're getting more people to your website OR more of them are actually buying. Either way, more sales = more money. Let's calculate how much.

What you need:

• Leads: How many people visit/see your stuff now
• Δ Leads: How many MORE people will visit (if you're bringing more traffic)
• Δ Conversion Rate: The improvement in % who buy
  Example: Currently 2% buy, you'll make it 2.6% → Enter 0.006 (that's 0.6 percentage points better)
• AOV: Average amount each buyer spends

Real example: Your website gets 50,000 visitors per month. Currently 2% buy something ($120 average). You're going to redesign the site so 2.6% buy instead.

50,000 visitors
Current: 2% buy → 1,000 buyers
After: 2.6% buy → 1,300 buyers (300 more!)
Each spends $120
Extra revenue: 300 × $120 = $36,000/month

4. Pricing Uplift 💰 (Charge More)

In Plain English: You're raising the price. Super simple math: how much more per thing × how many things.

What you need:

• Units: How many things you'll sell at the new price
• Old Price: What you charge now
• New Price: What you'll charge after the increase

Real example: You have a SaaS app with 500 paying customers at $49/month. You're raising it to $59/month (they're getting new features, it's worth it!).

500 customers
Currently pay: $49/month
Will pay: $59/month
Difference: $10 more per customer
Extra revenue: 500 × $10 = $5,000/month

5. Upsell / Cross-sell 🎁 (Want Fries With That?)

In Plain English: You're offering something extra to people who already bought from you. Like "Want to add priority support for $99?" Some will say yes. Let's calculate how much they'll spend.

What you need:

• Customers: How many people you'll offer this to
• Take Rate: What % will say yes (be realistic!)
  Example: 20% say yes → Enter 0.20
• Upsell AOV: How much the add-on costs

Real example: You sell software to 1,000 companies. You create a "Premium Support" package for $200. You think 20% will buy it (because you surveyed them and they seemed interested).

1,000 customers see the offer
20% say "yes please!" → 200 buyers
Each pays $200
Extra revenue: 200 × $200 = $40,000

6. Churn Reduction 🔒 (Stop Customers From Leaving)

In Plain English: Right now, X% of your customers cancel every month. You're going to make fewer people cancel. That means you KEEP revenue that you would have lost. Keeping money is the same as making money!

What you need:

• Baseline MRR: Your monthly subscription revenue (how much comes in every month)
• Δ Retention: How much better you're keeping customers
  Example: Currently 95% stay (5% leave), you'll make 97% stay → Enter 0.02
• Window: How many months to count (usually 12 for annual planning)

Real example: You have $100,000/month in subscriptions. Currently 5% cancel monthly (losing $5,000/month). You'll improve it so only 3% cancel (losing $3,000/month). You save $2,000/month.

$100,000 monthly revenue
Keep 2% more customers (was 95%, now 97%)
That's 0.02 × $100k = $2,000/month saved
Over 12 months: $2,000 × 12 = $24,000/year preserved

7. Capacity Unlock 🚀 (Fix The Bottleneck)

In Plain English: Right now you can't serve everyone who wants to buy because something is maxed out (servers, seats, hours, inventory). You're fixing that bottleneck. Now you CAN serve more people = more sales.

What you need:

• Extra Units: How many MORE things you can now sell/serve
• AOV: How much each one is worth
• Demand Constrained?: Important! Only select "Yes" if people DON'T actually want more.
  If you have a waitlist → "No". If nobody's asking → "Yes"

Real example: Your SaaS can only handle 1,000 users (server limit). You have 1,200 people wanting to sign up! You upgrade servers so you can serve the extra 200 people at $100/month each.

Currently maxed at 1,000 users
Can now serve 200 MORE
Each pays $100/month
Demand exists: Yes (people are waiting!)
Extra revenue: 200 × $100 = $20,000/month
(If no one wanted to buy, this would show $0 - fixing capacity only helps if demand exists)

⚖️ Adjustments (The Honest Stuff You Subtract)

Sometimes you make money but also lose some. Better to be honest upfront:

• Discounts: Did you offer 20% off? Subtract what you gave away
  Example: Made $10k but gave $2k in discounts → Subtract $2k
• Refunds: Some people will return stuff. How much usually?
  Example: Historically 5% ask for refunds → Subtract 5%
• Cannibalization: Does your new thing steal sales from your old thing?
  Example: New product makes $50k but old product loses $10k → Subtract $10k

Why bother? Because showing realistic numbers builds trust. Clients respect honesty.
