Margin: Measuring Profitability

Margins tell you how much of every rupee you bring in actually turns into profit. They're one of the clearest signs of whether your business model actually works. You need to watch two types.

Gross Margin shows how efficiently you're making or delivering your product. Calculate it by taking what it costs to make your stuff away from your revenue, then dividing by revenue.

• If you're selling software, your gross margins should be really high because once it's built, adding another customer costs basically nothing.

• If you're in manufacturing or retail, your margins will be tighter because every sale comes with real costs attached.

Net Margin is the whole story. It's your net profit divided by revenue, times 100. This includes absolutely everything:

• What you pay your team

• Rent and utilities

• Marketing costs

• Taxes and interest

• Every other expense that comes up

Good margins show everyone, especially investors, that you've got spending under control and you're building something sustainable. If your margins are razor thin or negative, that's a red flag. Maybe you're not charging enough, maybe operations are eating too much cash, or maybe your suppliers are overcharging you. Whatever it is, thin margins mean you need to act fast before things get worse.

Equity: Ownership and Control

Equity shows who owns what piece of your startup. It's split between founders, early team members (usually through stock options), and investors who've backed you. Your equity percentage tells you how much of the company is yours and how much control you have over the big calls.

Here's where it gets complicated. When you raise money, you're pretty much always giving up some ownership. You're trading a piece of your company for the cash you need to scale.

• Say you own 100% at the start and sell 20% to investors. Now you're at 80%.

• Raise another round and that percentage drops further.

This isn't automatically bad. A smaller piece of something way bigger beats owning everything of something that goes nowhere. But you need to understand what you're trading off:

• Give away too much too soon, especially when your valuation is low, and you might end up without enough ownership to stay fired up

• Lose too much control and you can't run the company the way you want

• Get it right and you've got the money you need while still calling the shots

Understanding equity helps you work out funding deals that get you growth capital without losing what matters most.

Return on Investment (ROI): Measuring Efficiency

ROI is one of the most useful numbers you'll track. It tells you if what you're spending is actually worth it. The math is straightforward: take your profit from something, divide it by what you spent on it, multiply by 100 for a percentage.

Say you drop ₹50,000 on a marketing campaign and it brings in ₹2,00,000 in revenue with ₹1,00,000 profit. Your ROI is 200%. Clear winner. But if you spend ₹1,00,000 on some new tool that barely does anything, that's a red flag telling you to rethink that choice.

ROI helps you decide about everything:

• Marketing campaigns and where to advertise

• New product features and what to build

• Hiring decisions and growing your team

• Tech investments and which tools to buy

• Which types of customers to go after

It keeps you honest. Startups don't have money to waste, so every rupee needs to pull its weight. Tracking ROI makes sure you're putting money where it actually brings results instead of just crossing your fingers and hoping.

Gross and Net Profit: Understanding the Bottom Line

These two numbers together show you the real story of how your business is doing.

Gross profit is your revenue minus what it directly costs to make or deliver your product or service. It shows how efficient your operations are:

• If your gross profit is strong, you're good at what you do and pricing things right

• If it's weak, you've got issues with either how much it costs to produce or your pricing strategy

Net profit is the number that matters most. It's revenue minus absolutely everything:

• What it costs to make your product

• Salaries and what you pay your team

• Rent and your space

• Marketing and promotion

• Software and subscriptions

• Taxes and interest

• Every other expense that comes up

This is what you actually keep. This is what's left to put back into growing, save for rough patches, or eventually pay out to owners.

Understanding the difference between the two helps you pinpoint exactly what's broken:

Maybe your gross profit is strong but your net profit is terrible. That means your core business works fine, you're just bleeding money on overhead.

Or maybe both are weak. That's telling you to rethink how you price things and what you're spending.

Either way, these numbers show you where you really stand and what needs to change.

Burn Rate: Tracking Your Cash Consumption

Burn rate is how fast you're going through your cash. For most startups, especially early on, you're spending more than you're making while you build and grow. That's normal. What's not okay is burning through cash without knowing how long you've got left.

Your runway gets calculated by taking your cash in the bank and dividing it by what you spend each month:

• If you've got ₹10,00,000 sitting there and you're spending ₹2,00,000 every month, you've got five months of runway.

• Five months to either start making enough to cover costs, raise more money, or make some serious cuts

This number should keep you up at night in a good way. It sharpens your focus:

• When you know you've got six months of runway, you're not messing around with projects that don't matter

• You'll focus hard on what actually brings in money or gets you closer to your next funding round

• You'll make tough calls faster because you know time's running out

Keep a close eye on your burn rate. Check it at least monthly, weekly if cash is tight. When your runway starts disappearing faster than planned, act quickly:

• Start talking to investors early

• Trim the fat without cutting into what actually drives your business

• Find ways to speed up revenue

• Don't wait until you're on your last month. By then, you're out of options.

EBITDA: Evaluating Operational Performance

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. Sounds complicated, but it's actually really helpful. It shows how your core business is doing without all the financial and accounting stuff muddying the water.

Why does this matter? Because two companies might show really different net profits even though their actual businesses are just as strong:

• One might have borrowed money, so they're paying interest

• Another might own expensive equipment, so they've got depreciation eating into things

• They could be in different tax situations depending on where they are or how they're set up

EBITDA cuts through all that and shows you purely how well the actual business runs day to day.

Investors love EBITDA because it lets them compare companies on equal footing, especially within the same industry. For you as a founder, it shows you how efficiently you're actually running things:

• Are you keeping operations lean?

• Do your core economics hold up?

• Is your business model profitable before debt and taxes come into play?

EBITDA cuts through the clutter and gives you straight answers without all the financial noise.

ARR (Annual Recurring Revenue): Predictable Growth for SaaS Startups

If you're running a subscription business or SaaS company, ARR is absolutely huge. It measures the predictable, recurring money you're bringing in every year from subscriptions.

Here's a quick example: you've got 100 customers each paying ₹1,000 a month. That's ₹1,00,000 monthly recurring revenue, which adds up to ₹12,00,000 in ARR.

Why does this matter so much? Because it lets you see what's coming:

• One-time sales are great but you never know when the next one's coming. You're always chasing.

• Recurring revenue means you wake up each month already knowing what's in the bank.

• It makes planning simpler, growth steadier, and your business worth more.

Tracking ARR also shows you how well you're keeping customers:

• If your ARR keeps climbing, you're not just signing people up, you're keeping them happy enough to stick around

• If it's flat or dropping even though you're getting new signups, you've got a churn problem

• People are bailing as fast as they're coming in, and you need to fix that right now

For investors, especially in SaaS, ARR is one of the first things they check. Strong, growing ARR shows you're building something people actually want and will keep paying for.

Customer Acquisition Cost (CAC): Measuring Marketing Efficiency

CAC shows you how much you're spending to get each new customer. You figure it out by taking everything you spend on sales and marketing over some period and dividing by how many new customers you got.

So if you spent ₹2,00,000 on marketing last month and got 20 customers, your CAC is ₹10,000 per customer.

This number only makes sense when you stack it up against Customer Lifetime Value, or LTV, which is how much money you expect to make from a customer over your whole relationship with them:

• The standard rule is LTV should be at least three times your CAC for growth that'll last

• If you're spending ₹10,000 to get a customer who only ever pays you ₹15,000, you're in trouble

• Your margins are way too thin and there's no room for operations costs, mistakes, or people leaving

• But if that customer pays you ₹50,000 over time, now you've got something that works

Watching CAC over time tells you if your marketing is getting better or worse:

• If CAC is going up, maybe your market's getting crowded, your ads are getting stale, or competition is pushing costs up

• If it's going down, you're getting better at finding and converting the right people

• Either way, it's info you need to adjust what you're doing

Conclusion

Finance can feel daunting, especially when you'd rather be working on your product or connecting with customers than analyzing numbers. But here's what matters: these ten terms aren't about becoming a financial expert. They're about knowing if you're actually making progress or just running in circles.

When you understand valuation, cash flow, margins, equity, ROI, profits, burn rate, EBITDA, ARR, and CAC, you can make smart decisions fast. You'll know when to spend and when to hold back. You'll spot warning signs before they become disasters. You'll talk the same language investors do, which means better conversations and better deals.

Financial literacy isn't a bonus for startup founders anymore. It's basic survival. The startups that make it aren't always the ones with the coolest ideas. They're usually the ones whose founders understand their numbers well enough to make the right calls when it matters.

Learn these terms. Check your numbers all the time. Make decisions based on what the data says, not what you hope will happen. That's how you take your startup from just an idea to something real that lasts.
