CAC, LTV & SaaS Growth Calculators for European Businesses

Currency-aware calculators in EUR (€) for European Union businesses. Model your customer acquisition cost, lifetime value, ROAS, and more — with example scenarios in your local currency.

The European Union spans diverse markets — from Germany's enterprise software sector to France's growing startup ecosystem and the Nordics' PLG-first culture. Pricing in euros (€) lets founders standardize metrics across eurozone countries without worrying about intra-European exchange rates.

European SaaS companies often face longer sales cycles in enterprise segments and more conservative buyer behavior compared to the US. This makes CAC payback period especially important: tying up capital for 18+ months in a market where follow-on funding may be smaller requires careful planning.

These calculators handle euros natively so you can model your unit economics, plan marketing budgets, and benchmark growth metrics in the currency your team and investors actually use — no awkward USD conversions cluttering your board deck.

Example Scenarios in EUR

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

A Berlin-based SaaS spending €40,000/month on a mix of LinkedIn ads and SDR outbound acquires 60 enterprise trials, converting 40 to paid — a CAC of €1,000. At €150 ARPU with 82% margin and 2% churn, LTV is roughly €6,150.
A Paris DTC brand runs €8,000 in Instagram ads generating €36,000 in revenue: a 4.5:1 ROAS. With 50% margin, break-even is 2.0:1, leaving healthy profit.
A Nordic PLG tool at €1.5M ARR with 4% monthly churn models churn impact: without improvement, only 61% of starting MRR remains after 12 months — reducing churn to 2% preserves 78%.

All Calculators in EUR (€)

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
