How it's calculated
The ROAS formula
Step 1 — ROAS
ROAS = Revenue from ads ÷ Ad spend
$150 ÷ $35 = 4.3x
$150 ÷ $35 = 4.3x
Step 2 — Estimate weekly bookings
Weekly clicks = (Daily spend ÷ CPC) × 7
Bookings = Clicks × Conversion rate
($5 ÷ $1.20) × 7 = 29 clicks → 29 × 8% = 2 bookings
Bookings = Clicks × Conversion rate
($5 ÷ $1.20) × 7 = 29 clicks → 29 × 8% = 2 bookings
Step 3 — Cost per booking
CPB = Total weekly spend ÷ Bookings from ads
$35 ÷ 2 = $17.50 per booking
$35 ÷ 2 = $17.50 per booking
Step 4 — Break-even ROAS
Break-even ROAS = 1 ÷ Gross profit margin
Studio No. 4 gross margin ≈ 70%
Break-even = 1 ÷ 0.70 = 1.43x
Any ROAS above 1.43x is profitable. Target: 4x+
Studio No. 4 gross margin ≈ 70%
Break-even = 1 ÷ 0.70 = 1.43x
Any ROAS above 1.43x is profitable. Target: 4x+

| Spend tier | Daily | Monthly | Bookings/mo | Revenue/mo | ROAS |
|---|---|---|---|---|---|
| Starter — Meta only | $5 | $150 | 8–15 | $600–$1,125 | 4–7x |
| Growth — Meta + retargeting | $15 | $450 | 20–35 | $1,500–$2,625 | 3–6x |
| Scale — Meta + Google Ads | $30 | $900 | 45–65 | $3,375–$4,875 | 4–5x |
| Full funnel — all channels | $50 | $1,500 | 80–110 | $6,000–$8,250 | 4–6x |
Projections based on 2026 Sydney market CPCs (Meta: $0.90–$1.50, Google: $2.50–$4.50), average booking value of $75, and a 6–10% click-to-booking conversion rate with a direct Square booking link. Conservative mid-range estimates — strong Reel creative or a viral post can push ROAS significantly higher.

Scale rule: Never increase daily budget by more than 30% at a time. Going from $5 to $50 overnight resets Meta's learning phase and destroys performance. Scale in steps: $5 → $8 → $12 → $20, waiting 5 days between each increase.

If ads cost $20 to acquire one new client, the lifetime ROAS is $2,700 ÷ $20 = 135x. A first visit ROAS of 4x massively understates the real return. Every new client from ads is not a $75 transaction — it's a potential $2,700 relationship over three years.
