Treats management fees and landing page costs as first-class inputs instead of measuring return on raw ad spend alone, which is how ROAS overstates results.
Enter your numbers first, then use the niche guidance below to interpret the output against in-house marketers, ppc freelancers, and owners running google ads accounts between roughly $1,000 and $50,000 in monthly spend..
ROAS and ROI answer different questions. ROAS compares revenue to ad spend only; ROI also charges the campaign for setup, landing pages, management fees, and tools. An account can show a 4x ROAS and still lose money once a $1,500 monthly management fee and thin product margins enter the math.
Use the setup work as the initial investment, then enter attributed monthly revenue and the full monthly cost of running the account. The output shows real return, the month the setup cost pays back, and what the return annualizes to if performance holds.
Monthly net profit is attributed revenue minus total monthly cost, including ad spend, management, and tools. ROI divides cumulative net profit over the period by the initial setup investment. Payback period divides setup cost by monthly net profit, and the optional tax and discount rates adjust profit and NPV.
A home services company pays $3,500 for account setup, landing pages, and call tracking. The account attributes $14,000 in monthly revenue. Monthly costs are $8,500: $7,000 in ad spend and $1,500 in agency management. They model twelve months.
Net profit is $5,500 a month, so setup pays back in under one month and the year looks strong. The number to challenge is the $14,000: if it includes jobs that would have arrived organically, recompute with only incremental revenue before scaling the budget.

No. ROAS is revenue divided by ad spend. This model charges the account for setup, management, and tools, then shows return on the setup investment with full monthly costs included.
Into monthly costs, alongside ad spend. If you pay a percentage of spend, convert it to a dollar amount at your planned budget.
Model the steady state after ramp, then add the ramp months' losses to the initial investment. That keeps the payback estimate honest.
Run the same full-cost model for paid social spend.
Evaluate a multi-channel campaign as a single investment.
Confirm product margins can absorb acquisition costs before scaling ads.
Frames ROI around seasonality, lead cost, close rate, crew capacity, rework, safety, trucks, equipment, and material price volatility.
Connects ROI to patient volume, treatment mix, chair utilization, hygiene recall, insurance reimbursement timing, and equipment capacity.
