JavaScript is off. The results below show the fixed example. Enable JavaScript to calculate
your own scenario, or use the formulas below.

Advertising spend USD The advertising cost for the period you want to evaluate.

Other campaign costs USD Include allocated software, number usage, fees, or other costs. Avoid counting a cost twice.

Tracked calls calls The calls associated with that campaign and period. Use a whole number.

Calls that qualify % The share of tracked calls that meet your definition of a relevant inquiry.

Qualified inquiries that become customers % The share of qualified inquiries you expect to win. This is not a percentage of all calls.

Revenue per new customer USD Use a consistent revenue horizon, such as the first completed job. This is revenue, not profit.

Gross margin % Revenue left after the direct cost of delivering the product or service, before the campaign costs above.

Estimated campaign return

73.1%
Gross profit less campaign costs, divided by campaign costs.

Example return: 73.1%. Contribution after campaign costs: $3,800.00.

#### Cost per qualified inquiry

$43.33 Includes advertising and other campaign costs.

#### Cost per new customer

$173.33 Total campaign cost divided by estimated new customers.

#### Revenue return on ad spend

3× Estimated revenue divided by advertising spend only.

#### Customers to cover campaign costs

18 Rounded up, using the gross margin you entered.

The calculation, explained

### Follow the numbers from call to contribution.

Use figures for one campaign and one consistent period. The calculator starts with illustrative values; it does not read your account or predict the improvement that call tracking software will create. Changing an assumption shows how the arithmetic changes, not what your team is guaranteed to achieve.

Qualified inquiries Tracked calls × qualification rate. If 200 calls have a 60% qualification rate, the estimate is 120 qualified inquiries.

New customers Qualified inquiries × close rate. Winning 25% of 120 qualified inquiries produces an estimate of 30 customers.

Revenue New customers × revenue per customer. With $500 per customer, 30 customers produce $15,000 in estimated revenue.

Gross profit Revenue × gross margin. At a 60% margin, $15,000 in revenue leaves $9,000 before campaign costs.

Campaign return (Gross profit − total campaign costs) ÷ total campaign costs × 100. With $5,200 in campaign costs, the example return is about 73.1%.

Break-even customers Total campaign costs ÷ gross profit per customer, rounded up. This covers the campaign costs entered, not every expense in the business.

Make the assumptions useful

### Change one thing. Understand its effect.

- 01

#### Test call quality

Keep volume and spend fixed, then adjust the share of calls that qualify. Notice how inquiry cost changes.

- 02

#### Test the close rate

Keep qualified inquiries fixed and change the share that becomes customers. Separate sales handling from traffic quality.

- 03

#### Review customer value

Use a consistent revenue horizon. Compare the first completed job with another clearly defined period only when costs are also comparable.

- 04

#### Include the relevant costs

Add campaign expenses not already included in advertising spend or gross margin. Avoid double-counting the same cost.

Read the result in context

### An estimate you can question.

Fractional customer counts are expected values in a planning scenario. The break-even customer count is rounded up because an actual campaign needs whole customers to cover its entered costs. The tool shows Not available when a rate would divide by zero, and Not achievable when positive costs cannot be covered by the entered customer margin.

The calculator keeps your entered figures in the page while you use it. It does not send them to Lead Source or save them as account data. Reloading the page restores the illustrative example. For software subscription and usage charges, use the separate pricing estimator.

Frequently asked questions

### A few more things, explained.

Explore the details. Open a question for the answer.

What does this call tracking ROI calculator estimate? +

It estimates qualified inquiries, customers, revenue, gross profit, campaign contribution, and return from the assumptions you enter. It is a planning tool, not a forecast of product performance.

Does the calculator predict how much Lead Source will increase my revenue? +

No. It shows the arithmetic of your inputs. A change in the scenario does not prove that software will produce that change in your actual campaign.

What should I enter as advertising spend in the calculator? +

Enter the advertising cost for the campaign and period being evaluated. Use the same campaign and period for the call count and keep other allocated costs in their separate field.

Which expenses belong in the other campaign costs field? +

Include relevant allocated costs such as software, number usage, fees, or creative work when they are not already counted elsewhere. Avoid including the same expense twice.

Is the calculator's close rate a percentage of all calls? +

No. It is the percentage of qualified inquiries that become customers. The qualification rate first converts raw calls into qualified inquiries.

Why does this calculator ask for gross margin? +

Revenue alone does not account for the direct cost of delivering a product or service. Gross margin estimates what remains before the campaign costs are deducted.

What is the difference between the displayed ROI and ROAS? +

ROI here compares contribution after campaign costs with total campaign costs. ROAS compares estimated revenue with advertising spend only; it does not account for delivery costs or other campaign costs.

Does the calculator's contribution equal my company's net profit? +

No. It deducts the campaign costs entered from estimated gross profit. Other overhead, taxes, and expenses outside those assumptions are not included.

Why can the calculator show a fraction of a customer? +

A planning scenario uses expected values from percentages. Fractional customers express that expectation; the break-even customer count is separately rounded up to a whole customer.

Why might a calculator result say Not available? +

A rate cannot be calculated when its denominator is zero. For example, cost per qualified inquiry is unavailable when no inquiries qualify, and ROI is unavailable when total campaign cost is zero.

What does Not achievable mean for the break-even result? +

It means positive campaign costs cannot be covered when the entered revenue and margin provide no gross profit per customer. Change the assumptions or review the business model.

Can the ROI calculator display a negative return? +

Yes. A negative result means the estimated gross profit does not cover the entered campaign costs. The page labels the scenario as below campaign break-even.

Are the figures I enter into the calculator sent to Lead Source? +

No. The calculator performs its calculations in the page and does not submit the input values to Lead Source. Reloading restores the illustrative starting values.

Can I use lifetime customer revenue in this scenario? +

You can choose a longer revenue horizon, but use consistent costs and margin assumptions and label the horizon. Do not present that estimate as profit already earned during a short campaign period.

Where should I calculate my actual Lead Source software bill instead? +

Use the separate estimator on the Pricing page for the software plan and supported usage inputs. This ROI calculator evaluates campaign economics rather than generating an invoice.
