How should an early-stage startup think about its costs?
Quick answer
Put every rupee you spend into five buckets, and know which costs stay the same and which grow as you grow. This one exercise tells you more about your business than your P&L does.
The mistake most founders make
They track *how much* they spend, but not the *shape* of it. So they can't tell you their margin on a single sale, because fixed and variable costs are all mixed together. That means they don't actually know if growing makes them healthier or just bleeds cash faster.
The five buckets
Every business spends in the same five places. — what it takes to deliver one unit: cloud, materials, delivery people, transaction fees. These usually grow with sales. — rent, tools, upkeep. These mostly stay the same. Sales & marketing — your growth engine; this is where your cost to win a customer lives. R&D — money spent on the future, not on running today. Admin (G&A) — legal, finance, HR; needed, but keep it lean. What changes from business to business is *which* bucket is the biggest. A software company spends most on sales and R&D; a factory on materials and overheads; a services firm on people.
Why it matters when you raise
Once you split costs into “stays the same” and “grows with sales,” you can answer the questions an investor will ask: how much do you make on one sale, at what point do you break even, and what happens to your margin as you scale? ₹100 of spend that's mostly variable behaves very differently in a tough month than ₹100 that's mostly fixed.
Our honest take
You can't price, plan, or value a business until you've broken its costs apart. It's boring work, but it's what makes every other number believable. Do it first.
