Unit economics are the heartbeat of a startup. Revenue growth tells you how fast you are moving. Unit economics tell you whether that movement is building something valuable or quietly destroying it. This is the master guide: it covers the 3 universal metrics every startup must track, then links to a dedicated deep-dive for each of the 12 industries where Indian startups operate. Find your industry, read the full guide, and build your dashboard from there.
Key Takeaways
- CAC, LTV:CAC, and Gross Margin are the three metrics every startup must track regardless of industry or stage
- Each industry has 4 to 6 additional sector-specific metrics that investors will expect by Series A
- Gross margin is the foundation of all downstream metrics: LTV, CAC payback, and contribution margin all depend on it being structurally sound
- Unit economics must be tracked monthly, not only at fundraising — problems caught at 50 customers are fixable; at 50,000 they are crises
- The same metric means something different across industries: “contribution margin” in D2C is not the same calculation as in Food Tech or Logistics
- This series has 12 full industry guides — each covers 13 to 18 metrics specific to that business model with formulas and India-specific benchmarks

What Are Unit Economics and Why Every Startup Must Track Them
Unit economics measure the revenue and costs tied to a single unit of your business, usually one customer or one transaction. The core question they answer is: does acquiring and serving one customer generate more value than it costs? If the answer is yes, scaling accelerates value creation. If no, every new customer deepens the problem.
This distinction matters more than any other number in a startup. A company can grow 150% year-on-year while quietly destroying value at the customer level — burning through reserves, acquiring customers at twice what they ever return. Unit economics cut through that illusion. They measure the business at its most fundamental level, one customer at a time.
The second reason unit economics matter is compounding. Good unit economics improve with scale: acquisition costs fall as brand recognition grows, and revenue per customer rises as the product matures. Bad unit economics worsen with scale: every new customer at a loss deepens the hole. Catching this early, at 50 customers rather than 50,000, is the difference between a course correction and a crisis.
The 3 Universal Metrics Every Startup Tracks Regardless of Industry
Whether you are building a SaaS platform, a D2C brand, a marketplace, or a lending startup, three unit economics metrics apply to every business model. These are the foundation on which all industry-specific metrics are built.
CAC — Customer Acquisition Cost
The fully loaded cost of acquiring one new customer, including sales salaries, marketing spend, events, tools, and any referral fees. Not just ad spend.
LTV:CAC Ratio
The ratio that tells you whether your customer relationships are worth more than they cost to create. Below 3:1 means the business model needs structural work. Above 5:1 means you may be under-investing in growth.
Gross Margin
The percentage of revenue remaining after the direct costs of delivering your product or service. Every downstream metric — LTV, CAC payback, contribution margin — depends on gross margin being structurally sound. A low gross margin is not a stage-of-startup problem; it is a business model problem.
SaaS and B2B Software Unit Economics
SaaS is built on recurring revenue. The critical insight is that existing customer revenue — not new bookings — determines long-term viability. NRR above 100% means the installed base is growing on its own.
NRR Net Revenue Retention: are existing customers growing? | CAC Payback Period How many months to recover the cost of acquiring one customer? | Burn Multiple How much net burn does each rupee of new ARR cost? |
SaaS unit economics have 18 key metrics, including MRR, ARR, Gross Churn, NRR, CAC Payback, LTV:CAC, Rule of 40, Burn Multiple, and more. The full guide covers each with India-specific benchmarks.
Read the SaaS Unit Economics Guide →Fintech and Lending Unit Economics
Fintech unit economics are governed by credit quality as much as growth. NIM measures your spread. Gross NPA tells you if the book is healthy. Collection efficiency tells you whether you are actually collecting what you have lent.
NIM Net Interest Margin: the spread between what you earn and what you pay to borrow. | Gross NPA Non-Performing Assets as % of loan book. RBI scrutiny above 3%. | Collection Efficiency Amount collected vs. amount due. Target 95%+ for a healthy portfolio. |
The full Fintech guide covers 16 metrics including Yield on Portfolio, Net NPA, EMI Bounce Rate, DPD buckets, Cost per Loan, and Opex Ratio, with benchmarks for Indian NBFCs and digital lenders.
Read the Fintech Unit Economics Guide →D2C and E-commerce Unit Economics
D2C unit economics live or die on the contribution margin per order. After subtracting COGS, shipping, payment gateway fees, and returns from revenue, is there anything left? CAC and repeat purchase rate determine whether that margin is recovered over the customer lifecycle.
Contribution Margin per Order Revenue minus COGS, shipping, payment, and returns. The real profitability test. | CAC Blended CAC across all channels: Meta, Google, influencer, and organic. | Repeat Purchase Rate % of customers who order again. Target 30%+ for brand-level economics. |
The full D2C guide covers 16 metrics including AOV, ROAS, Return Rate, Inventory Turnover, LTV:CAC, Cart Abandonment Rate, and First Order Profitability.
Read the D2C Unit Economics Guide →Marketplace and Platform Startups
Marketplace economics require tracking both sides simultaneously. GMV is volume, not revenue. Take rate converts volume to revenue. Liquidity tells you whether buyers and sellers can consistently find each other — the metric that determines whether the platform actually works.
Take Rate Net revenue as % of GMV. The bridge between volume and actual revenue. | Liquidity Rate % of listings that result in a transaction. Below 15% signals supply-demand mismatch. | Buyer Retention Repeat buyers month-over-month. Target 40%+ for sustainable marketplace LTV. |
The full Marketplace guide covers 15 metrics including GMV, Supply CAC, Demand CAC, Order Fill Rate, Seller Retention, Dispute Rate, and Gross Profit per Transaction.
Read the Marketplace Unit Economics Guide →Logistics and Delivery Unit Economics
Logistics is an operations game. Cost per delivery determines whether the model is structurally profitable. FADR measures whether deliveries succeed on the first attempt, since re-deliveries destroy contribution margin. Vehicle utilization determines whether fixed assets are being used efficiently.
Cost per Delivery Total variable operating cost divided by deliveries. Must be below revenue per delivery. | FADR First Attempt Delivery Rate. Below 85% means re-delivery costs eat contribution margin. | Vehicle Utilization Actual trips vs. capacity. Below 70% means idle assets absorbing fixed cost. |
The full Logistics guide covers 15 metrics including Contribution Margin per Delivery, Fuel Cost per KM, On-Time Delivery Rate, SLA Adherence, Fleet Uptime, and Orders per Vehicle per Day.
Read the Logistics Unit Economics Guide →Edtech Unit Economics
Post-BYJU’s, Indian edtech has shifted from growth-at-all-costs to per-learner economics. Investors now ask for Outcome Rate alongside CAC. Course Completion Rate tells you whether the product works. LTV depends heavily on whether learners achieve the promised outcome and return for more.
Course Completion Rate % of enrolled learners who finish the course. Below 10% signals engagement failure. | Outcome Rate % achieving the stated outcome: placement, salary hike, certification. The new trust metric. | Trial-to-Paid Conversion Free users who convert to paid. Below 10% signals the trial is not demonstrating value. |
The full Edtech guide covers 15 metrics including CAC, LTV:CAC, Cohort Retention, ARPU, Instructor Utilization, Refund Rate, Content Production Cost per Hour, and more.
Read the Edtech Unit Economics Guide →Food Tech and Cloud Kitchens
Food tech unit economics must survive a 20-30% aggregator commission before contribution margin can even be calculated. Kitchen utilization determines whether fixed kitchen costs are spread across enough orders. Most cloud kitchens are profitable on paper until you account for Swiggy and Zomato commissions.
Contribution Margin per Order AOV minus food cost, packaging, delivery, and aggregator commission. | Kitchen Utilization Rate Actual orders vs. capacity. Below 60% means fixed costs per order are unsustainably high. | Aggregator Commission Rate Swiggy/Zomato commission as % of GMV. Typically 20-30%. Non-negotiable for most brands. |
The full Food Tech guide covers 15 metrics including AOV, Revenue per Kitchen, Food Cost Percentage, Packaging Cost, Repeat Order Rate, Order Cancellation Rate, and Customer LTV on platforms.
Read the Food Tech Unit Economics Guide →Healthtech and Telemedicine
Healthtech unit economics revolve around supply-side efficiency and patient retention. Doctor utilization determines whether the platform’s supply costs are covered. Patient retention is the proxy for trust: patients who return without being re-acquired have effectively zero marginal CAC.
Doctor Utilization Rate Consultation hours filled vs. available hours. Below 60% means supply cost exceeds revenue. | Patient Retention Rate Patients consulting again within 90 days. Repeat patients have near-zero marginal CAC. | Cost per Consultation Total platform cost per completed consultation. Sets the floor for sustainable pricing. |
The full Healthtech guide covers 14 metrics including ARPU, Consult-to-Repeat Rate, Patient Acquisition Cost, Prescription Fulfillment Rate, Diagnostic Order Rate, and more.
Read the Healthtech Unit Economics Guide →AgriTech
AgriTech unit economics are distorted by seasonality. Metrics spike during harvest season and collapse in the off-season, making monthly comparisons misleading without normalization. Working capital days is often the metric that kills agritech startups: procurement cash is tied up for 60-90 days before it can be recovered.
Farmer LTV Revenue per farmer x gross margin / annual churn. Seasonality makes this annual, not monthly. | Procurement Margin Selling price minus procurement price as % of selling price. Target 8-15% for commodity models. | Working Capital Days Days cash is tied up in crop inventory. High working capital days sink agritech cash flow. |
The full AgriTech guide covers 13 metrics including Farmer CAC, Revenue per Farmer, Farmer Retention Rate, Price Realization vs MSP, Advisory-to-Purchase Conversion, and Collection Efficiency.
Read the AgriTech Unit Economics Guide →PropTech and Real Estate
PropTech has the longest sales cycle of any consumer transaction: 30-90 days from first lead to booking. Agent productivity and the lead-to-booking funnel determine whether the operation is sustainable. Ancillary revenue from loans, interior, and insurance often adds 30-50% on top of core commission.
Site Visit-to-Booking Rate Bookings divided by site visits. Benchmark 5-15% for residential projects. | Revenue per Transaction Brokerage plus ancillary per deal closed. Core unit of proptech economics. | Agent Productivity Transactions per agent per month. Benchmark 1-2 for residential, lower for commercial. |
The full PropTech guide covers 13 metrics including Lead-to-Booking Rate, Cost per Lead, Commission Rate, Time to Close, Listing Inventory Turnover, Repeat Client Rate, and NPS.
Read the PropTech Unit Economics Guide →Consumer Apps and Gaming
Consumer app economics are driven by three things: do users come back (D1 retention), do they form a habit (DAU/MAU), and does a small percentage pay enough to fund the rest (ARPPU and conversion to paid). A high DAU/MAU with low ARPPU means a popular but un-monetized product.
DAU/MAU Ratio Daily vs. monthly active users. 20%+ is good, 40%+ signals habitual use. | D7 Retention Rate % of users returning on Day 7. Benchmark 10-20% for consumer apps. | ARPPU Average Revenue per Paying User. Reveals true monetization depth in the paying segment. |
The full Consumer Apps guide covers 15 metrics including ARPU, D1/D30 Retention, Churn Rate, K-factor, UA Cost, ROAS, Conversion to Paid, Session Length, and App Store Rating.
Read the Consumer Apps Unit Economics Guide →Travel Tech and OTAs
Travel tech economics require separating GBV from revenue. An OTA processing Rs.500 crore in GBV at a 6% take rate earns Rs.30 crore — before cancellations and refunds. Net Revenue Margin after all those leakages is the true picture. Repeat booking rate determines whether LTV justifies the high CAC of this category.
Take Rate Net revenue as % of GBV. Flights: 3-5%. Hotels: 10-15%. Holiday packages: 15-20%. | Net Revenue Margin Net revenue after cancellations and refunds divided by GBV. Benchmark 6-12%. | Repeat Booking Rate Customers booking again annually. Target 30-40%. Determines LTV vs. high CAC. |
The full Travel Tech guide covers 13 metrics including GBV, Ancillary Revenue per Booking, Cancellation Rate, Search-to-Book Conversion Rate, Customer Service Cost per Booking, and LTV:CAC.

Frequently Asked Questions
What are unit economics for startups?
Unit economics measure the revenue and costs associated with a single unit of your business, usually one customer or one transaction. They answer: does acquiring and serving one customer generate more value than it costs? The three universal unit economics metrics are CAC (Customer Acquisition Cost), LTV:CAC ratio, and Gross Margin. Every other industry-specific metric is built on top of these three.
Why do unit economics matter more than revenue growth?
Revenue growth tells you how fast you are moving. Unit economics tell you whether that movement is creating value or destroying it. A startup growing 100% year-on-year with a negative LTV:CAC ratio is building a larger loss with every customer it adds. By contrast, a startup growing at 60% with strong gross margins and a 5:1 LTV:CAC ratio is compounding value at scale. Investors at Series A and beyond now ask for cohort-level unit economics before any other number.
What is a healthy LTV:CAC ratio for Indian startups?
3:1 is the minimum acceptable threshold across most business models. For B2B and SaaS startups targeting Series A, 4:1 to 5:1 is the expected benchmark. For D2C and consumer businesses with lower gross margins, 2:1 to 3:1 may be acceptable if CAC payback periods are short. Ratios below 2:1 signal that the business model needs structural changes before you scale further.
Which metrics do investors look at first when reviewing unit economics?
Most investors start with gross margin, LTV:CAC ratio, and CAC payback period. These three together tell them whether the business can eventually be profitable, whether customer acquisition is economically rational, and how long cash is tied up before it is recovered. For specific industries, they then add sector-specific metrics: NRR for SaaS, NIM and Gross NPA for Fintech, Contribution Margin per Order for D2C and Food Tech, and FADR for Logistics.
At what stage should a startup start tracking unit economics?
From the first paying customer. At pre-Seed, track 3 to 5 core metrics. By Seed, have a full unit economics dashboard updated monthly. By Series A, investors will expect historical trends across multiple cohorts, not just a point-in-time snapshot. Founders who wait until fundraising to build this often discover structural problems with too little time and capital to fix them.
Is the same unit economics metric calculated the same way in every industry?
No. The same term often means something quite different across industries. Contribution Margin per Order in D2C (revenue minus COGS, shipping, payment, returns) is not the same calculation as Contribution Margin per Order in Food Tech (where aggregator commissions of 20-30% must also be subtracted). CAC in a SaaS business includes SDR salaries and marketing software; CAC in a marketplace must be calculated separately for the supply side and demand side. Always define what is included in your metric before comparing to benchmarks.
