A plan based on your assumptions. Actual campaign results can differ.
How it works
Daily budget compounds by your increase and respects your cap. CPA changes by your assumption at each step. Period spend / modeled CPA gives expected conversions.
Know the limits
These are user-defined planning scenarios, not predictions, guarantees, platform pacing limits or advice that an increase is safe. No paid API or account connection.

Plan a spend increase without hiding the trade-offs
A campaign can perform well at its current spend and behave differently when you increase the budget. This ad budget scaling calculator makes the proposed increase and CPA assumption visible at every step. Use it to review a staged spending plan, compare a flat budget with a larger one or see how a rising acquisition cost changes the expected contribution. It does not declare an increase safe.
How to use Ad Budget Scaling Calculator
Enter the current daily budget, percentage increase, number of steps, days per step and a daily spending cap. The first step applies the first increase immediately.
Add baseline CPA, average conversion value, pre-ad margin and the assumed CPA change per step. Enter zero CPA change only when that is the scenario you intend to test.
Build the schedule and inspect each period’s spend and modeled contribution. Review totals and the extra spend above a flat-budget plan before using the output.
What do the results mean?
Budget growth compounds until the cap is reached. The supplied CPA change still compounds in later periods at the cap. Expected results are averages; the schedule does not model platform learning, audience saturation or every auction effect. Contribution after ads excludes fixed costs and tax.
What to do next
Revisit the plan with measured campaign data after each real change. Use PPC Metrics Calculator to keep the observed metrics comparable with the assumptions.

Common questions about Ad Budget Scaling Calculator
Is increasing ad spend by 20% always safe?
No. There is no universal safe increase built into this tool. The percentage is your scenario input, and the calculator cannot observe the campaign conditions needed to judge risk.
Does the schedule include time at my original budget?
No. Step 1 applies the first planned increase. If you need a baseline period in a separate financial plan, account for it outside this schedule rather than assuming it is included.
