10 Business Metrics Every Nepali Entrepreneur Should Know: CAC, LTV, Churn, ROAS, NPS & More

CAC, Customer Lifetime Value, LTV:CAC, Churn, ARPU, ROAS, Payback Period, Dilution, Market Cap and NPS explained with simple formulas and Nepali business examples.

Whether you run a small café in Kathmandu, an online store in Lalitpur, a software startup in Baneshwor, or a growing company serving customers across Nepal, business numbers eventually become impossible to ignore.

But financial and startup terminology can sound complicated.

What exactly is CAC? Why does every startup talk about LTV? What does a 4:1 LTV:CAC ratio mean? Why can a company grow rapidly while still losing customers? What is ROAS? What happens to a founder's ownership when investors put money into a company? And how can a company have a large market capitalization without having the same amount of cash in its bank account?

To make these ideas easier to remember, let's follow Suman, a fictional Nepali entrepreneur who starts a coffee-subscription business called Himalayan Brew Club in Kathmandu.

The numbers are fictional and are used only to explain the concepts.

By following Suman's business from customer acquisition to fundraising and, later, a hypothetical stock-market listing, we can see how ten important business metrics connect with one another.

The 10 Business Metrics at a Glance

1. CAC — Customer Acquisition Cost

Customer Acquisition Cost (CAC) measures the average amount a business spends to acquire a new customer.

In simple language:

CAC tells Suman how much it costs him to win one new customer.

Suppose Suman spends NPR 600,000 on Instagram and Facebook advertising, sales activities and other direct customer-acquisition expenses during one month.

During that period, he gains 300 new subscribers.

The basic calculation is:

CAC = Total Acquisition Cost ÷ Number of New Customers

Therefore:

NPR 600,000 ÷ 300 = NPR 2,000

Suman's CAC is NPR 2,000 per new customer.

CAC calculations can vary depending on which sales and marketing costs a company includes, so consistency is important when comparing months or customer segments. The American Marketing Association's CAC guidance similarly emphasizes agreeing on what belongs in the calculation.

2. LTV — Customer Lifetime Value

LTV stands for Customer Lifetime Value.

It estimates how much economic value a customer generates during their relationship with a company.

Suppose a Himalayan Brew Club customer pays NPR 1,500 per month and remains a customer for an average of 10 months.

A simple revenue-based calculation is:

LTV = Average Monthly Revenue × Average Customer Lifespan

NPR 1,500 × 10 = NPR 15,000

The customer generates approximately NPR 15,000 in revenue during the relationship.

But there is an important distinction: revenue is not profit.

Suppose Himalayan Brew Club has a 60% gross margin after the direct cost of coffee, packaging and delivery.

Then an approximate gross-profit-based LTV would be:

NPR 15,000 × 60% = NPR 9,000

That difference matters when Suman compares LTV with CAC.

Stripe notes that there are multiple ways to calculate customer lifetime value and that gross margin, retention and customer behavior can materially change the result.

3. LTV:CAC Ratio — Customer Value Compared With Acquisition Cost

Now Suman has two important numbers:

LTV = NPR 9,000

CAC = NPR 2,000

So:

LTV:CAC = 9,000 ÷ 2,000 = 4.5

Himalayan Brew Club has an estimated 4.5:1 LTV:CAC ratio on this calculation.

In practical terms, the estimated gross-profit value of the average customer is 4.5 times the acquisition cost.

However, this should not be described as “the company makes 4.5 times its money” or as proof that the entire business is profitable. LTV:CAC focuses on customer economics; the business still has salaries, rent, technology, taxes, administration and other costs.

Stripe describes LTV:CAC as a ratio used alongside CAC payback to understand customer acquisition economics, while noting that benchmarks vary by business.

4. Payback Period — How Quickly Does Suman Recover CAC?

A company might have good customer economics but still face cash-flow pressure.

Suman spends NPR 2,000 to acquire one customer.

That customer produces:

NPR 1,500 monthly revenue

With a 60% gross margin:

NPR 1,500 × 60% = NPR 900 monthly gross profit

Now calculate CAC payback:

Payback Period = CAC ÷ Monthly Gross Profit per Customer

NPR 2,000 ÷ NPR 900 = 2.22 months

So Suman recovers the acquisition cost in approximately 2.2 months, assuming the customer continues generating the expected gross profit.

This does not mean every rupee after month 2.2 is “pure profit.” The business still has overhead and other expenses.

Stripe defines CAC payback as the time required to recover customer acquisition cost and notes that shorter payback can reduce pressure on cash flow.

5. Churn Rate — The Customers Who Leave

Churn rate measures the percentage of customers who leave during a particular period.

Imagine Himalayan Brew Club starts July with 1,200 subscribers.

During July, 60 customers cancel.

The simplified customer churn calculation is:

Churn Rate = Customers Lost ÷ Customers at Start × 100

60 ÷ 1,200 × 100 = 5%

Suman's monthly customer churn is therefore 5%.

Churn matters because losing customers can reduce future revenue and customer lifetime value. Stripe also distinguishes customer churn from revenue churn, which measures lost recurring revenue rather than simply the number of customers lost.

A useful question for Suman is not simply, “How many customers left?”

He should also ask:

Why did they leave?

Maybe the coffee was delivered late, the subscription was too expensive, the product quality changed, or customers simply no longer needed the service.

6. ARPU — Average Revenue Per User

ARPU means Average Revenue Per User.

It tells Suman how much revenue the average user generates during a specific period.

Suppose Himalayan Brew Club has 1,200 active paying subscribers and generates NPR 1.8 million in monthly revenue.

Then:

ARPU = Total Revenue ÷ Number of Users

NPR 1,800,000 ÷ 1,200 = NPR 1,500

The monthly ARPU is NPR 1,500.

ARPU is especially useful when a business changes pricing or introduces premium plans.

For example, Suman could have:

• Basic plan: NPR 1,200

• Premium plan: NPR 1,800

• Family plan: NPR 2,500

If more customers move to premium plans, ARPU may increase even when the total number of customers stays the same.

Stripe describes ARPU as a period-specific measure of average revenue generated per user or customer and recommends consistent definitions and segmentation when comparing ARPU.

7. ROAS — Return on Ad Spend

ROAS stands for Return on Ad Spend.

It measures revenue attributed to advertising compared with advertising expenditure.

Suppose Suman spends:

NPR 100,000 on Facebook advertising

and the campaign generates:

NPR 450,000 in attributed sales

The calculation is:

ROAS = Advertising Revenue ÷ Advertising Spend

NPR 450,000 ÷ NPR 100,000 = 4.5

So the campaign generated 4.5:1 ROAS, or NPR 4.50 in attributed revenue for every NPR 1 spent on advertising.

But ROAS is not the same as profit.

If Suman's coffee, packaging, delivery, payment fees and other variable costs consume most of that revenue, a high ROAS does not automatically mean a high profit margin.

Shopify's current guidance also emphasizes that an acceptable ROAS depends on factors such as margins and operating costs, while advertising platforms can use different attribution methods.

8. Dilution — What Happens When Investors Buy New Shares?

Two years later, Suman wants to expand Himalayan Brew Club beyond Kathmandu.

Before fundraising, the company has:

1,000,000 shares

Suman owns:

400,000 shares

So his ownership is:

400,000 ÷ 1,000,000 = 40%

An investor agrees to invest in exchange for 250,000 new shares.

The company's total shares become:

1,250,000

Suman still owns 400,000 shares.

But his percentage is now:

400,000 ÷ 1,250,000 = 32%

So his ownership falls from 40% to 32%.

That is share dilution.

Importantly, dilution does not automatically mean that Suman's investment became less valuable. The company may use the new capital to expand, hire employees, open new stores or develop technology. His percentage becomes smaller, but the value of the overall company may change.

Carta defines share dilution as a reduction in an existing shareholder's ownership percentage when new shares are issued.

9. Market Cap — How Much Is a Public Company Worth?

Market Cap is short for Market Capitalization.

Unlike the private-company fundraising example above, market capitalization is primarily used for companies whose shares trade publicly.

Imagine that, after major expansion and a hypothetical future listing on the Nepal Stock Exchange, Himalayan Brew Limited has:

10 million outstanding shares

and each share trades at:

NPR 50

Then:

Market Cap = Share Price × Outstanding Shares

NPR 50 × 10,000,000 = NPR 500,000,000

The company's market capitalization would be:

NPR 500 million

That does not mean the company has NPR 500 million sitting in its bank account.

Market capitalization represents the market value of the outstanding equity based on the current public share price.

10. NPS — Net Promoter Score

NPS stands for Net Promoter Score.

It is a customer-feedback metric based on a 0-to-10 recommendation question:

“How likely are you to recommend Himalayan Brew Club to a friend or colleague?”

Customers are divided into three groups:

Promoters: scores 9–10

Passives: scores 7–8

Detractors: scores 0–6

Imagine Suman receives 200 responses:

• 120 Promoters

• 50 Passives

• 30 Detractors

Promoters represent:

120 ÷ 200 = 60%

Detractors represent:

30 ÷ 200 = 15%

Therefore:

NPS = 60% − 15% = 45

Himalayan Brew Club's NPS is 45.

NPS ranges from -100 to +100. A company should interpret the result in context rather than treating one universal number as “good” for every industry.

The official Net Promoter methodology defines promoters as 9–10, passives as 7–8, and detractors as 0–6.

How These 10 Metrics Connect

The real value comes from looking at the numbers together.

Suman's business might look like this:

These metrics tell different parts of the same story.

CAC tells Suman what customer acquisition costs.

LTV estimates the value of keeping a customer.

LTV:CAC connects acquisition cost with customer economics.

Churn shows how quickly customers are leaving.

ARPU shows how much revenue the average customer generates.

ROAS evaluates advertising revenue relative to ad spend.

Payback Period tells Suman how quickly acquisition costs can be recovered.

Dilution becomes important when Suman raises outside capital.

Market Cap becomes relevant if the company eventually has publicly traded shares.

And NPS gives Suman another way to understand whether customers are willing to recommend the business.

No single number can tell the whole story.

A company may have strong sales but high churn. It may have impressive ROAS but poor margins. It may grow revenue while burning cash. A startup founder may own a smaller percentage after fundraising but have a stake in a much larger business.

That is why business metrics should be read as a system, not a collection of isolated numbers.

Frequently Asked Questions

What is CAC in business?

CAC, or Customer Acquisition Cost, is the average amount a company spends to acquire one new customer.

CAC = Acquisition Costs ÷ New Customers

What is LTV?

LTV, or Customer Lifetime Value, estimates the value a customer generates throughout the relationship with a business.

What is a good LTV:CAC ratio?

There is no universal ratio that is appropriate for every company. The economics depend on the business model, margins, retention, customer segment and growth stage. A frequently cited SaaS benchmark is around 3:1, but it should be treated as a benchmark rather than a universal rule.

What is churn rate?

Churn rate measures the percentage of customers or subscribers lost during a particular period.

What is ARPU?

ARPU means Average Revenue Per User. It shows the average revenue generated by each user over a specified period.

What is ROAS?

ROAS means Return on Ad Spend. It measures advertising-attributed revenue relative to advertising expenditure.

What is dilution in a startup?

Dilution occurs when new shares are issued and existing shareholders consequently own a smaller percentage of the company.

What is market capitalization?

Market capitalization is calculated by multiplying the current public share price by the number of outstanding shares.

What is NPS?

NPS, or Net Promoter Score, is calculated by subtracting the percentage of detractors from the percentage of promoters.

NPS = % Promoters − % Detractors

Final Takeaway

For a new entrepreneur in Nepal, these terms may initially look like investor jargon.

They are not.

They are simply different ways of answering practical business questions.

CAC: What does it cost me to get a customer?

LTV: What value does that customer generate?

LTV:CAC: Does the customer economics make sense relative to acquisition cost?

Churn: How many customers am I losing?

ARPU: How much revenue does an average customer generate?

ROAS: Is my advertising generating attributed revenue?

Payback Period: How quickly can I recover acquisition costs?

Dilution: What happens to my ownership when I issue new shares?

Market Cap: What is the public market value of the company's equity?

NPS: Are customers willing to recommend the business?

For someone building a business in Kathmandu, Pokhara, Biratnagar, Butwal, Nepalgunj or anywhere else in Nepal, learning these numbers can make conversations about marketing, startups, fundraising and company growth much easier to understand.

The goal should not be to chase one “perfect” number.

The goal is to understand the relationships between the numbers—and use them to make better business decisions.
