CAC, LTV & SaaS Growth Calculators for Indian Businesses

Currency-aware calculators in INR (₹) for India businesses. Model your customer acquisition cost, lifetime value, ROAS, and more — with example scenarios in your local currency.

India's SaaS ecosystem has exploded, with companies in Bangalore, Chennai, Hyderabad, and Delhi NCR building products for both domestic and global markets. Pricing in rupees (₹) is essential for founders serving Indian SMBs and mid-market customers, where price sensitivity is high and average contract values are lower than in Western markets.

Indian SaaS companies often achieve remarkably low CAC thanks to cost-effective engineering and digital marketing talent, but must pair that with proportionally lower LTV expectations. The key metric to watch is CAC payback period — keeping it under 6 months is critical when operating on tighter margins and smaller round sizes common in India.

These calculators work natively in INR so you can model your unit economics in the currency your customers pay, plan marketing budgets that align with Indian ad-spend costs, and present clear ₹-denominated metrics to domestic investors.

Example Scenarios in INR

These are illustrative examples using realistic numbers in INR — not benchmarks. Use the calculators below with your own data.

A Bangalore SaaS spending ₹8,00,000/month on Google and LinkedIn acquires 200 customers — a CAC of ₹4,000. With ₹1,500 ARPU, 70% margin, and 4% churn, LTV is approximately ₹26,250, yielding a strong 6.6:1 ratio.
A Delhi e-commerce brand runs ₹3,00,000 in Meta ads generating ₹15,00,000 in revenue: a 5:1 ROAS. At 35% margin, break-even ROAS is 2.86:1 — solidly profitable.
A Chennai HR-tech startup at ₹1.5 Cr ARR adds ₹8L net new ARR on ₹6L quarterly S&M spend — a 1.33 Magic Number, indicating efficient growth worth accelerating.

All Calculators in INR (₹)

CAC Calculator

Measure how much you spend to acquire each new customer by dividing total acquisition spend by new customers acquired.

CAC = Total Acquisition Spend ÷ New Customers Acquired

LTV Calculator

Estimate the total revenue a customer generates over their relationship with your business.

LTV = (ARPU × Gross Margin) ÷ Churn Rate

LTV:CAC Ratio

Compare customer lifetime value to acquisition cost to assess whether your growth is profitable and sustainable.

LTV:CAC Ratio = LTV ÷ CAC

ROAS Calculator

Measure how much revenue your advertising generates for every dollar spent.

ROAS = Revenue from Ads ÷ Ad Spend

CAC Payback Period

Find how many months it takes to recover the cost of acquiring a customer through their gross margin contribution.

Payback Period = CAC ÷ (ARPU × Gross Margin)

Break-even ROAS

Determine the minimum ROAS required to break even after accounting for gross margin and other variable costs.

Break-even ROAS = 1 ÷ Gross Margin

Budget Planner

A free marketing budget calculator that reverse-engineers the spend you need to hit revenue targets from CAC and funnel metrics.

Budget = Target Customers × CAC

Churn Impact

Quantify how monthly churn affects revenue, LTV, and the value of retention improvements.

Revenue at Month N = Starting MRR × (1 − Churn)^N

Funnel Planner

Model conversion rates at each funnel stage to forecast leads, opportunities, and closed revenue.

Customers = Traffic × Visit-to-Lead × Lead-to-Opp × Opp-to-Close

MRR Calculator

Calculate monthly recurring revenue (MRR) instantly: Active Customers × ARPU, with growth and churn context for SaaS.

MRR = Active Customers × ARPU

ARR Calculator

Calculate annual recurring revenue (ARR) instantly: MRR × 12, the investor-standard SaaS scale metric.

ARR = MRR × 12

Magic Number

Measure how efficiently your sales and marketing spend generates new annual recurring revenue.

Magic Number = New Bookings (ARR) ÷ Prior Quarter S&M Spend

Burn Multiple

Calculate your SaaS Burn Multiple with the standard formula (Net Burn ÷ Net New ARR) to measure capital efficiency.

Burn Multiple = Net Burn ÷ Net New ARR

Rule of 40

Combine revenue growth rate and EBITDA margin to measure overall SaaS business health.

Rule of 40 = Revenue Growth % + EBITDA Margin %

ASP Calculator

Find the average revenue per closed deal to benchmark pricing and sales performance.

ASP = Total Revenue ÷ Number of Deals

AOV Calculator

Calculate the average amount customers spend per order to optimize pricing and promotions.

AOV = Total Revenue ÷ Number of Orders

NRR Calculator

Calculate NRR (Net Revenue Retention), also called NDR (Net Dollar Retention), including expansion, contraction, and churn.

NRR = (Starting MRR + Expansion − Contraction − Churn) ÷ Starting MRR × 100

CPA Calculator

Measure how much you spend for each conversion (lead, signup, or purchase) in a campaign or channel.

CPA = Total Ad Spend ÷ Conversions

CPC Calculator

Calculate cost per click (CPC) instantly: divide ad spend by clicks to see how much you pay for each visit from paid ads.

CPC = Total Ad Spend ÷ Clicks

CPM Calculator

Calculate CPM (cost per mille / cost per thousand impressions) with the standard formula: (Ad Spend ÷ Impressions) × 1,000.

CPM = (Total Ad Spend ÷ Impressions) × 1,000

CTR Calculator

Calculate click-through rate (CTR) as a percentage: divide clicks by impressions and multiply by 100.

CTR = (Clicks ÷ Impressions) × 100

ROI Calculator

Measure profitability of an investment as net profit divided by cost.

ROI = ((Revenue - Cost) ÷ Cost) × 100
