Use Google Ads Performance Planner to forecast spend, conversions, CPA, and revenue scenarios without treating Google’s estimate as a guarantee.
Google Ads Performance Planner estimates how changes to budgets and bidding targets could affect spend, conversions, cost per conversion, and conversion value. Use it to compare scenarios before changing live campaigns.
Treat the output as a forecast, not a promise. The planner cannot know future competitor behavior, lead quality, closing rates, business capacity, or changes to the website.
What is Google Ads Performance Planner?
Performance Planner is a forecasting tool inside Google Ads. It uses recent campaign performance, simulated auctions, seasonality, competition, landing-page information, and other signals to estimate what may happen under different budget or bidding choices.
It can help answer questions such as:
- What might happen if daily budgets increase?
- Could the same spend be distributed more efficiently?
- How could a different CPA or ROAS target affect volume?
- Which campaigns appear able to use more budget?
- What might happen if budget moves from one campaign to another?
It cannot answer whether the resulting leads will be qualified or whether the sales team will close them.
What changed in Performance Planner in 2026?
Google states that, effective March 9, 2026, Performance Planner no longer supports Display and Video campaign plans or plans based on impression-share metrics.
Google’s current eligibility guidance covers supported Search, Standard Shopping, and Performance Max planning, subject to campaign-history and activity requirements. Eligibility can vary by campaign type, bid strategy, recent clicks, conversions, and how recently bidding changed.
If a campaign is missing, check eligibility before assuming the tool is broken.
What you need before creating a plan
Performance Planner is only as useful as the account measurement beneath it.
Confirm that:
- The right conversion actions are primary
- Duplicate or weak actions are not inflating the Conversions column
- Revenue values are reasonably accurate
- Recent tracking outages are documented
- Campaigns have enough stable history
- Conversion lag is understood
- The forecast period reflects real business capacity
Read primary versus secondary conversions before forecasting if every form open, page view, and phone-click currently counts as a primary result.
How to create a Performance Planner forecast
- Open Tools in Google Ads.
- Select Performance Planner.
- Create a new plan.
- Choose the supported campaign type.
- Select the campaigns or portfolio to include.
- Choose the date range.
- Select the conversion goal or metric that matters.
- Review Google’s forecast at the current settings.
- Adjust the spend, CPA, ROAS, or other available target.
- Compare multiple scenarios before applying any change.
Save the current-state forecast as the baseline. Without a baseline, the larger-budget scenario has nothing useful to compare against.
Read the forecast in business terms
The tool may show spend and conversions. A business owner still needs to translate that into qualified leads, customers, and revenue.
Suppose the planner forecasts this monthly change:
| Scenario | Ad spend | Reported leads | Cost per lead |
|---|---|---|---|
| Current | $12,000 | 160 | $75 |
| Proposed | $15,000 | 180 | $83.33 |
Check the math:
$12,000 ÷ 160 = $75 per lead
$15,000 ÷ 180 = $83.33 per lead
The proposed scenario adds 20 leads for $3,000 of additional spend:
180 − 160 = 20 additional leads
$15,000 − $12,000 = $3,000 additional spend
The marginal cost per additional lead is:
$3,000 ÷ 20 = $150 per additional lead
That marginal number is often more useful than the blended cost per lead. The business is not deciding whether to buy all 180 leads from zero. It is deciding whether the next 20 leads are worth $3,000.
Add lead quality and sales data
Now suppose 60% of reported leads are qualified and 25% of qualified leads become customers.
For the proposed scenario:
180 × 60% = 108 qualified leads
108 × 25% = 27 customers
If the business can serve only 20 additional customers, the forecast may exceed capacity. If the projected leads come from a weaker campaign or geography, the historical qualification rate may not apply.
Use CRM and call data to pressure-test the model. Do not assume every Google Ads conversion has equal value.
How to compare Performance Planner scenarios
Build at least three:
| Scenario | Purpose |
|---|---|
| Hold | Shows what current settings may produce |
| Controlled increase | Tests a modest budget or target change |
| Upper bound | Shows the point where marginal efficiency becomes unattractive |
Compare:
- Total spend
- Total useful conversions
- Cost per useful conversion
- Marginal cost for added conversions
- Expected customers and revenue
- Operational capacity
- Downside if the forecast is wrong
The best forecast is not automatically the one with the most conversions. It is the scenario that fits cash flow, capacity, and customer value.
Why the forecast can be wrong
Performance Planner is based partly on recent conditions. Results may differ because of:
- A competitor increasing or reducing spend
- A new promotion
- Tracking changes
- Website changes
- A service-area or inventory constraint
- A change in lead quality
- Weather or unusual demand
- Sales-team performance
- A bid-strategy learning period
- A future event not represented in recent data
Google says forecasts are refreshed daily and typically use recent auction information from the previous 7–10 days, adjusted for seasonality. This makes them responsive, but it also means a short abnormal period can influence the view.
Performance Planner versus budget recommendations
Performance Planner is a scenario tool. A budget recommendation is a suggested account action. Neither should replace business judgment.
The planner may even propose a budget of zero for a campaign if its model sees a more efficient allocation elsewhere. Before acting, ask whether that campaign serves a protected brand, location, product, or customer goal that the model does not understand.
Review the Google Ads daily-budget rules before implementing a plan. An average daily budget is not a strict daily spending cap.
When to use Performance Planner
Use it for:
- Monthly or quarterly budget discussions
- A planned seasonal increase
- Comparing CPA or ROAS targets
- Finding the likely point of diminishing returns
- Reallocating spend among mature campaigns
- Creating a range for a business forecast
Google recommends planning weekly during unstable market conditions rather than relying on a monthly or quarterly forecast.
When not to trust it alone
Do not rely on it alone when:
- Conversion tracking recently broke
- Campaigns were just launched or restructured
- Primary conversion goals are wrong
- A major promotion has no comparable history
- The business cannot handle more calls or orders
- Lead quality varies sharply by campaign
- The decision depends on profit rather than reported conversion value
A practical decision rule
Use Performance Planner to define a range, then make a smaller live change and measure the actual result.
For example:
- Model a 25% increase.
- Review marginal cost and capacity.
- Apply a smaller controlled increase.
- Allow for conversion lag.
- Compare actual qualified leads and revenue with the forecast.
- Continue, hold, or reverse based on business results.
Frequently asked questions
Is Google Ads Performance Planner accurate?
It can provide a useful directional forecast, but it is not a guarantee. Accuracy depends on stable campaigns, correct measurement, recent data, and how closely future conditions resemble the modeled period.
Does Performance Planner change campaigns automatically?
Creating and editing a plan does not itself change live campaigns. Google currently provides an option to apply suggested changes, so review every proposed budget and bid change before confirming it.
Why is a campaign missing from Performance Planner?
It may be an unsupported type or fail requirements involving recent activity, conversions, bidding, or recent strategy changes. Check Google’s current eligibility table for that campaign type.
Does Performance Planner include conversion lag?
Google says the planner includes conversion-delay estimates for supported forecasts. The business should still compare results only after enough time has passed for customers to convert.
Should I use the forecasted cost per lead as my budget target?
Not by itself. Add qualification rate, close rate, customer value, profit, and capacity. A forecasted lead that does not become a customer has limited business value.
