Calculator guide

Understanding Social Advertising Budget Calculator

A target-customer media budget is a back-solved funnel, not a single CPM multiplication.

Back-solve landing visitors At 2.8%, every target customer requires about 35.714 landing visitors.
Back-solve clicks The arrival rate accounts for clicks that do not become recorded landing visits.
Back-solve impressions CTR is applied as a proportion, not the number 1.4.
Price media and fixed cost CPM is divided by 1,000 impressions before multiplication.

Calculation method

How the calculation works

Back-solve the complete impression-to-customer funnel, price impressions at the entered CPM, and add separately entered fixed campaign cost. Divide the customer target by each downstream rate in reverse order, price the required impressions at CPM, add fixed cost, and reconcile gross profit.

Detailed calculation process

Back-solve the complete paid-social acquisition funnel

The default targets 240 customers with 2.8% visitor conversion, 92% landing arrival, 1.4% CTR, $11 CPM, $310 revenue per customer, 60% margin, and $6,500 fixed cost.

General formula: Visitors = Customers/(r_v/100)Clicks = Visitors/(r_a/100)Impressions = Clicks/(CTR/100)Media = Impressions(CPM/1000)Budget = Media+FixedGrossProfit = Customers v(m/100)Contribution = GrossProfit-BudgetBudgetPerCustomer = Budget/Customers The funnel is solved backward from the target. Each rate increases the required upstream volume, and CPM prices impressions per thousand before fixed campaign cost is added.

Budget, Contribution Total campaign budget and gross contribution after campaign ($).

Worked substitution with the default inputs

1. Back-solve landing visitors Visitors = 240/(2.8/100)Visitors = 8,571.4286 At 2.8%, every target customer requires about 35.714 landing visitors.
2. Back-solve clicks Clicks = 8,571.4286/(92/100)Clicks = 9,316.7702 The arrival rate accounts for clicks that do not become recorded landing visits.
3. Back-solve impressions Impressions = 9,316.7702/(1.4/100)Impressions = 665,483.5847 CTR is applied as a proportion, not the number 1.4.
4. Price media and fixed cost Media = 665,483.5847(11/1000) = $7,320.3194Budget = 7,320.3194+6,500 = $13,820.3194 CPM is divided by 1,000 impressions before multiplication.
5. Reconcile campaign contribution GrossProfit = 240(310)(0.60) = $44,640Contribution = 44,640-13,820.3194 = $30,819.6806Budget/Customer = $57.5847 Gross profit less the complete campaign budget closes to the displayed contribution.

The default requires about 665,484 impressions and a $13,820.32 total budget, leaving $30,819.68 modeled contribution.

Worked situations

Practical examples

  • The default targets 240 customers with 2.8% visitor conversion, 92% landing arrival, 1.4% CTR, $11 CPM, $310 revenue per customer, 60% margin, and $6,500 fixed cost.
  • The default requires about 665,484 impressions and a $13,820.32 total budget, leaving $30,819.68 modeled contribution.

Better inputs

Useful tips

  • Change one input at a time and confirm both the result and visual move.
  • Keep the units stated beside every field.
  • Retain intermediate precision and round only the reported result.

Before relying on the result

Limitations and common mistakes

  • Platform forecasts can differ from delivery.
  • Attributed customers may include nonincremental conversions.
  • Taxes, refunds, agency fees, and downstream service costs are excluded.
