MRR is the most-used SaaS metric — but Excel makes it harder than it should be. Here are 3 ways to calculate MRR in Excel, plus how Talon does it in one click.
Monthly Recurring Revenue (MRR) is the sum of all active monthly subscription revenue. For annual contracts, divide the annual amount by 12. MRR is the single most-tracked SaaS metric because it normalizes revenue across plan types and contract lengths.
If your data has columns for customer, plan, billing frequency, and amount, the simplest MRR formula is:
=SUMIF(billing_freq, "monthly", amount) + SUMIF(billing_freq, "annual", amount)/12
This works for clean data but breaks down when you have multi-currency, mid-month upgrades, or refunds.
Build a pivot table grouping by month (Insert → PivotTable, drag billing_month to Rows, normalized_amount to Values). Use SUM aggregation. This handles multi-currency if you pre-normalize, but loses expansion vs new MRR breakdown.
Power Query (Get Data → From Excel Workbook) handles the full MRR waterfall — Beginning MRR, New, Expansion, Contraction, Churn, Ending MRR. Best for serious analysis but takes 2 hours to set up.
Upload your Stripe export or any CSV with date + amount columns and ask: "Compute MRR with new/expansion/contraction/churn breakdown by month."
Talon's SaaS Metrics Analyst agent generates the full waterfall, charts the trend, and flags any month where NRR drops below 100%. Takes 30 seconds vs 2 hours in Excel.
Excel can calculate MRR with the right formulas and 2+ hours of setup. AI tools like Talon do it in 30 seconds. For monthly board reporting, the time savings compound.
