How It Works
Enter monthly recurring revenue components: new MRR, expansion MRR, contraction MRR, and churned MRR for the period. The tool computes net new MRR, ending MRR, annualized run rate, and growth rate versus prior month. Board decks quote ARR run rate as MRR times twelve at month end close. Investors annualize snapshot for valuation multiples. Investor update slide often shows MRR bridge waterfall from prior month to current with annotations on large logo wins and churn losses. Present MRR bridge in investor updates with narrative annotation on largest new logo wins contraction events and churn losses to explain net new MRR movement month over month. Investor deck MRR waterfall should annotate largest logo wins and churn losses explaining net new MRR bridge month over month clearly.
Review net new MRR, ending MRR, ARR run rate as MRR times twelve, and month over month growth percentage. Separate expansion from new logo MRR to diagnose growth quality. Net new MRR bridge explains whether growth came from new logos, expansion, or recovered churn. Net revenue retention above one hundred percent means expansion exceeds churn on installed base even before new logos. Annualize cautiously: ARR run rate assumes current MRR persists twelve months without churn expansion or new sales which rarely holds exactly in growing SaaS businesses. Expansion MRR from existing accounts signals product value delivery without proportional new logo acquisition cost. ARR run rate snapshot annualizes current MRR without assuming future churn expansion or new sales which rarely holds exactly twelve months. Contraction MRR without logo churn signals downgrade pressure requiring product analytics investigation separate from new logo acquisition performance review. Net revenue retention above one hundred percent implies expansion MRR offsets churn and contraction making run rate growth exceed new logo additions alone. Annual prepay discounts flatten recognized MRR versus cash collected requiring normalization before comparing to monthly billed competitors in same vertical. Logo churn versus revenue churn diverge when small customers cancel while enterprise expansions dominate net MRR movement in land and expand SaaS model. Sales commission accelerators tied to run rate milestones can inflate reported MRR with one time professional services bundled into first year contract value.

Common mistakes
Copying outputs without checking input units or stale market prices is a frequent error with MRR Run Rate Projector. Confirm tickers, percentages, and dates before acting.
Running a single baseline scenario ignores tail risks. Stress test with conservative inputs and compare against related tools listed below when the decision is material.
The Formula
currentARR = currentMrr × 12
rawMRR = currentMrr × (1 + growth)^months
churnAdjustedMRR = currentMrr × (1 + growth - churn)^months
ARR projection = churnAdjustedMRR × 12
breakEvenChurn = monthlyGrowthPct
Ending MRR equals starting plus new plus expansion minus contraction minus churn. ARR run rate equals ending MRR times twelve. ARR run rate is snapshot not forward contract value. Snapshot ARR run rate not contracted forward revenue. Churn after snapshot not reflected. Board reporting should show net new MRR bridge narrative alongside ARR run rate snapshot each month end close. Usage based MRR normalization divides quarterly overage by three before adding to base subscription run rate for apples to apples comparison against flat rate SaaS peer benchmarks in same vertical market segment analysis report. Educational estimates only not personalized advice consult qualified professional before major financial decisions.

FAQ
What is the difference between MRR and ARR?
MRR is contracted recurring revenue normalized to monthly amount. ARR run rate equals MRR times twelve. Net new MRR equals new plus expansion minus contraction minus churn. Contraction MRR without full churn signals downgrade pressure on product value. Annual contract paid upfront should be normalized to monthly MRR for run rate comparability. Normalize annual prepay contracts to monthly MRR by dividing contract value by twelve for run rate bridge comparability.
What growth rate should I enter?
Expansion MRR comes from existing customers upgrading seats or tiers. Contraction is downgrade without full churn. Separating components shows whether growth depends on new logos or land and expand motion. Logo MRR and revenue MRR bridges differ when ARPU shifts. Contraction without churn signals downgrade pressure worth product analytics investigation.
What is the break even churn rate?
Month over month growth rate equals net new MRR divided by starting MRR times one hundred. Seasonality in B2B can distort single month growth. Seasonal Q4 enterprise closes inflate single month growth. Seasonality in enterprise Q4 can inflate December net new MRR versus January slowdown. Contracted but not yet live MRR in implementation backlog should be footnoted separately from recognized run rate to avoid double counting pipeline as current period recurring revenue in investor update deck metrics slide.
Why show both raw and churn-adjusted MRR?
ARR run rate is snapshot metric not forward guarantee. Churn and contraction can reverse run rate quickly. Run rate assumes no future churn or expansion not realistic for long horizons. Burn multiple equals net burn divided by net new ARR for venture efficiency tracking. Burn multiple metric pairs net burn with net new ARR for venture efficiency tracking alongside MRR run rate snapshot reporting.
What related growth tools should I use?
Use Burn Rate Runway for cash planning alongside MRR growth. LTV CAC Ratio validates unit economics supporting MRR growth spend. Burn multiple equals net burn divided by net new ARR for venture efficiency metric. LTV CAC validates whether MRR growth spending is economically sustainable. LTV CAC ratio validates whether MRR growth spending level economically sustainable at current unit economics and churn profile assumptions.
How do I use this MRR run rate projector on phone or tablet?
Yes. MRR Run Rate Projector runs entirely in your mobile browser with the same formulas as desktop. Optional localStorage may remember inputs on your device when enabled in browser settings.
Where is my data stored when I use MRR Run Rate Projector?
