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
