You can build a credible SaaS metrics dashboard in a spreadsheet in an afternoon — if you get the structure right the first time. Most home-grown dashboards break because the raw data and the calculations live in the same place, so every refresh means re-deriving formulas by hand. Here is the structure that holds up.
Use three layers. A raw tab where you paste the export untouched. A model tab that references the raw tab with formulas. A dashboard tab that only shows the finished charts and numbers. When you refresh next month you replace the raw tab and everything downstream recalculates. Never type a number directly onto the dashboard.
From Stripe (or your biller) you want, per subscription: customer ID, plan amount, billing interval, status, started date, canceled date. Normalize everything to a monthly amount first — divide annual plans by 12 — or your MRR will be wildly overstated the month an annual deal closes. This single normalization step is where most DIY dashboards go wrong.
Total MRR is easy; the useful view is the bridge. For each month compute: starting MRR, + new MRR, + expansion, − contraction, − churn, + reactivation = ending MRR. This requires comparing each customer's amount this month vs. last month. A pivot or a keyed lookup (customer ID + month) does it. The bridge is what lets you answer "are we growing because of new logos or because existing customers expand?"
From the bridge you derive the rest:
Pull cash balance and average net burn (cash out − cash in per month). Runway = cash ÷ net burn. Put it top-left on the dashboard in months. It is the number you will look at most.
If you would rather not rebuild this each time, a ready-made template already encodes the layered structure, the MRR bridge, and the retention math — paste your export and it fills in.
From scratch, expect roughly 6–20 hours including debugging cohort and retention formulas. A pre-built template gets you the same output in the time it takes to paste one export.
Failing to normalize annual plans to a monthly amount, which overstates MRR, and treating downgrades as churn instead of contraction, which corrupts your retention numbers.
Yes. Use three layers — a raw paste tab, a formula model tab, and a display dashboard tab — so monthly refreshes are a single paste. SaaSDash ships exactly this structure.
