Call Tracking Breakeven Cost Calculator

Set defensible budgets for call tracking campaigns by aligning acquisition cost with actual profit per sale. Enter your close rate and contribution margin to reveal the breakeven cost per tracked call, then optionally layer in an ROI multiple and call volume to surface monthly spend caps and profit potential.

Share of tracked calls that convert into paying customers.
Net profit or contribution margin per closed deal.
Defaults to 4× return when blank.
Defaults to 0 and is used to show monthly spend caps and profit potential.

Use actual conversion and margin data when setting bid caps. Reconcile with finance before making large budget shifts.

Examples

  • 22% close rate, $650 margin, 4× ROI, 1,200 calls ⇒ Profit per tracked call: $143.00 USD • Maximum cost per call at 4.00× ROI: $35.75 USD • Close rate applied: 22.00% • Monthly spend cap: $42,900.00 USD • Monthly gross profit from tracked calls: $171,600.00 USD • Net profit after spend cap: $128,700.00 USD
  • 15% close rate, $420 margin, optional fields blank ⇒ Profit per tracked call: $63.00 USD • Maximum cost per call at 4.00× ROI: $15.75 USD • Close rate applied: 15.00%

FAQ

How should I handle multi-touch attribution?

Use the margin attributed to calls alone, or reduce the profit per sale to reflect other channels that share credit so the breakeven cost stays conservative.

Can I use revenue instead of profit?

Yes, but the calculator assumes the dollar input is contribution margin. If you enter revenue, the cost per call will be overstated relative to profit-based guardrails.

What if I target a different ROI by channel?

Change the optional ROI multiple to match the return threshold finance expects for paid search, display, or affiliate calls.

Does this factor in call center staffing?

Not directly. Add staffing costs to the per-sale margin or tighten the ROI multiple so your cost per call reflects the labor required to service inbound leads.

Additional Information

  • Profit per tracked call multiplies contribution margin by your close rate so cost limits stay tied to true unit economics.
  • ROI multiple defaults to 4×, a common benchmark for inbound marketing programs seeking strong payback on media and tooling.
  • Adding tracked call volume shows how acquisition caps translate into monthly budgets and net profit after spend.
