Bootstrapped SaaS MRR Tracker

What you get

A six-sheet Excel workbook built for bootstrapped SaaS founders tracking monthly recurring revenue from $0 to $50k MRR. It covers every core metric — MRR by plan, all four MRR movement types, cohort retention, ARPU, a simple P&L, and cash runway — without the overhead of a fundraising model. A dedicated reference tab explains every metric in plain English.

Who it's for

Indie hackers and bootstrapped SaaS founders who pull a Stripe revenue report once a month and want clean, reliable numbers without connecting an API or hiring an analyst. This is the right tool at the moment your spreadsheet feels too loose but a full analytics platform feels like overkill.

What's inside

• MRR by Plan sheet — monthly recurring revenue broken out by pricing tier, so you can see which plans are growing or stalling
• MRR Movement sheet — tracks all four movement types: new MRR, expansion MRR, contraction MRR, and churned MRR
• Cohort Retention sheet — retention curves by signup cohort, showing where customers drop off over time
• Customer Count and ARPU sheet — active customer totals alongside average revenue per user, updated from your monthly Stripe export
• Simple P&L sheet — revenue against operating costs, giving you a clear monthly profit and loss without accounting complexity
• Cash Runway sheet — current cash balance divided against your burn rate, with a rolling months-of-runway figure
• How To Read Your Numbers tab — plain-English definitions of every metric in the workbook so the data is always interpretable

How to use it

Open the file in Microsoft Excel or Google Sheets. At the end of each month, export your revenue report from Stripe and enter the figures manually into the designated input cells — no integrations, no API keys required. The formulas and charts update automatically from there, giving you a current snapshot of your business in under thirty minutes.
