Monthly ↔ Annual Revenue Converter
Annualise monthly revenue (MRR → ARR), break annual targets into monthly milestones, or forecast with seasonal growth. With GST-inclusive/exclusive toggle.
About this converter
This converter solves a tedious but important arithmetic problem for solopreneurs, SaaS founders, freelancers, and small businesses: switching cleanly between monthly and annual revenue, with optional growth rate compounding. Enter ₹5 lakh monthly and see ₹60 lakh annual; enter ₹50 lakh annual and see the implied ~₹4.17 lakh monthly.
Three places this matters for Indian businesses. First, GST registration thresholds: services hit mandatory GST at ₹20 lakh annual; goods at ₹40 lakh. Watch your monthly run-rate so you register on time and avoid penalties. Second, presumptive taxation (44AD/44ADA): if total gross receipts cross ₹50 lakh for professionals or ₹2 crore for business, you exit the presumptive scheme and must maintain full books. Third, SaaS valuations: investors quote ARR multiples (5-15× for Indian SaaS); MRR × 12 is the basis, with growth-adjusted projections for what next year looks like.
The converter’s growth-rate option also helps reverse-engineer feasibility. If you need ₹3 crore ARR and you’re at ₹15 lakh/month MRR today, you need ~7% MoM growth for 24 months — concrete, testable, planning-grade math.
ARR (Annual Recurring Revenue) is the annualised run-rate of monthly revenue — key for SaaS businesses and subscription models. In India, GST-registered businesses must separate taxable turnover from GST collected. Your actual revenue (turnover) is ex-GST; the GST is collected on behalf of the government.
Why Monthly ↔ Annual Conversion Matters
Operations run on monthly numbers. Investors, banks, and tax authorities want annual numbers. SaaS founders quote MRR (Monthly Recurring Revenue); equity raises happen on ARR (Annual Recurring Revenue). Translating cleanly between the two — especially with growth rates baked in — is the most common arithmetic in early-stage business planning.
Simple multiplication (monthly × 12) works only when revenue is flat. For growing businesses, the compound monthly growth rate (MoM) changes the math substantially. A 10% MoM growth from a ₹5 L starting month turns ₹60 L flat-projected ARR into ~₹106 L compound-projected ARR.
Growth Rate Impact on Annual Revenue
| Starting MRR | 0% MoM (Flat) | 5% MoM | 10% MoM | 15% MoM |
|---|---|---|---|---|
| ₹1 Lakh | ₹12 L | ₹15.9 L | ₹21.4 L | ₹29.0 L |
| ₹5 Lakh | ₹60 L | ₹79.6 L | ₹1.07 Cr | ₹1.45 Cr |
| ₹10 Lakh | ₹1.2 Cr | ₹1.59 Cr | ₹2.14 Cr | ₹2.90 Cr |
| ₹25 Lakh | ₹3 Cr | ₹3.98 Cr | ₹5.35 Cr | ₹7.25 Cr |
| ₹50 Lakh | ₹6 Cr | ₹7.97 Cr | ₹10.69 Cr | ₹14.50 Cr |
Compound annual = MRR × ((1+r)^12 − 1) / r, where r is monthly growth rate.
GST Threshold Watch: Services need GST registration above ₹20 L annual turnover; goods above ₹40 L. At 10% MoM growth from ₹1 L MRR, you cross ₹20 L total revenue in month 9. Track monthly run-rate so registration isn’t a surprise.
Real-World Indian Examples
Example 1: Early-Stage SaaS
Bootstrapped Indian SaaS at ₹2.5 L MRR (₹30 L ARR flat) growing 8% MoM. By month 12, MRR = ₹6.3 L (₹75.6 L ARR run-rate). Cumulative 12-month revenue ≈ ₹47.4 L. Investors quote the EXIT ARR (₹75.6 L), but cash collected is the cumulative figure.
Example 2: Freelance Consultant
Flat ₹2 L/month consulting revenue = ₹24 L/year. Above ₹20 L threshold → GST registration mandatory. 18% GST on ₹2 L invoices = ₹36,000 collected and remitted each month. Income tax under presumptive scheme 44ADA: 50% of receipts (₹12 L) taxable.
Example 3: D2C Brand Pre-Series A
₹8 L monthly revenue at 12% MoM growth. ARR (compounded) = ₹1.92 Cr. T2D3 trajectory: triple year-1 to ₹5.76 Cr, triple year-2 to ₹17.3 Cr. This compounding is what Series A investors price into 8-12× revenue multiples.
Tracking Metrics That Matter
- MRR vs ARR for SaaS: Investor pitches use ARR. Operational dashboards use MRR. Always know both.
- Net Revenue Retention (NRR): For subscription businesses, NRR > 110% means existing customers are growing faster than churn — best growth signal.
- Burn multiple: Cash burned ÷ net new ARR. Under 1.5× is excellent for early-stage, under 2.5× acceptable.
- GST + presumptive scheme thresholds: ₹20 L (services GST), ₹40 L (goods GST), ₹50 L (44ADA exit), ₹2 Cr (44AD exit) — annual revenue triggers compliance changes.
- Seasonal businesses: Use trailing 12-month average for annual figures, not last month × 12. Festive/winter spikes distort flat extrapolation.
