A$ AUD

CAC, LTV & SaaS Growth Calculators for Australian Businesses

Currency-aware calculators in AUD (A$) for Australia businesses. Model your customer acquisition cost, lifetime value, ROAS, and more — with example scenarios in your local currency.

Australia's SaaS market is growing rapidly, with Sydney and Melbourne emerging as Asia-Pacific startup hubs. Operating in Australian dollars (A$) means your unit economics should reflect local pricing, GST considerations (10%), and the cost structures unique to the ANZ market — including higher average salaries for tech talent.

Australian founders often sell into both domestic and US markets simultaneously. Tracking metrics in A$ for local operations keeps your domestic P&L clean, while separate channel-level CAC analysis reveals whether offshore acquisition is cost-effective after currency conversion and time-zone overhead.

These calculators let you model everything in A$ so your numbers match what flows through your Xero or MYOB accounts — practical, local-currency metrics you can act on immediately.

Example Scenarios in AUD

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

A Sydney SaaS spending A$25,000/month on paid channels acquires 40 customers — a CAC of A$625. With A$110 ARPU, 80% margin, and 2.5% churn, LTV is approximately A$3,520, delivering a 5.6:1 LTV:CAC ratio.
A Melbourne DTC brand runs A$10,000 in Google Ads generating A$42,000 in revenue: a 4.2:1 ROAS. At 48% margin, break-even ROAS is 2.08:1 — profitable with room to scale.
An ANZ fintech at A$2M ARR with NRR of 108% retains and expands existing customers well, reducing reliance on new acquisition to sustain growth.

All Calculators in AUD (A$)

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
