Paid Ads / PPC calculators

Find out exactly how much revenue you're generating for every dollar spent on ads.

ROAS = Revenue from Ads ÷ (Ad Spend + Other Campaign Costs)

Find the minimum ROAS you need just to avoid losing money — before chasing anything higher.

Break-Even ROAS = 1 ÷ Gross Margin

Find the maximum you can afford to pay per click without blowing your acquisition budget.

Target CPC = Allowable Cost per Customer × Conversion Rate

Turn a budget and CPM into a realistic estimate of how many people you'll actually reach.

Reach = (Budget ÷ CPM × 1,000) ÷ Average Frequency

Get a starting-point budget split across channels, weighted by which ones actually perform.

Channel A Budget = Total Budget × (ROAS A ÷ (ROAS A + ROAS B + ROAS C))

See how much a higher Google Ads Quality Score could lower what you actually pay per click.

Estimated CPC ≈ (Competitor's Ad Rank ÷ Your Quality Score) + $0.01

Work backward from a reach goal to find out how much budget you actually need.

Budget Needed = (Target Reach × Target Average Frequency ÷ 1,000) × CPM

Check your actual average frequency against the point where performance typically starts declining.

Average Frequency = Total Impressions ÷ Unique Reach

Find out what's actually left over after ad spend and product costs — not just the revenue headline.

PPC Profit Margin = (Revenue − Ad Spend − Cost of Goods Sold) ÷ Revenue × 100

Calculate a value-based max bid from conversion rate, order value, and your target ROAS.

Max Bid = (Conversion Rate × Average Order Value) ÷ Target ROAS

Model how much return your next dollar of spend actually generates, as a channel starts to saturate.

Marginal ROAS = [k × (Current Spend + Additional Spend)^α − Current Revenue] ÷ Additional Spend, where k = Current Revenue ÷ Current Spend^α

See what share of the people who saw your ad actually clicked it — the fastest read on whether your creative and targeting match.

CTR = (Clicks ÷ Impressions) × 100

Work out what a thousand impressions actually costs you — the common currency for comparing awareness spend across platforms.

CPM = (Total Ad Spend ÷ Impressions) × 1,000

Find what you're actually paying for each visit — and whether that price leaves room for a profit once they land.

CPC = Total Ad Spend ÷ Clicks Received

Price a lead honestly, then check it against what a lead is worth once your close rate is applied.

CPL = Total Campaign Spend ÷ Leads Generated

Work out what one completed conversion costs you — the number every bid strategy is ultimately steering toward.

CPA = (Total Ad Spend + Other Campaign Costs) ÷ Conversions
