If you're bootstrapped and spending 10 hours a week on your side project instead of freelancing, that's real burn. $50/hr × 10 hrs × 4.33 weeks = $2,165/month you're not earning. Most burn rate calculators don't account for this.
So I built one that does. Toggle opportunity cost on and your "zero burn" runway suddenly looks a lot shorter. Also does gross vs net burn, runway in months, zero-cash date, and a 20% expense reduction scenario showing exactly how many months you'd gain.
I also shipped a break-even calculator alongside it. This one does month-by-month growth modeling with churn factored in, not just a single break-even number. There's a price increase scenario that shows how many fewer customers you'd need at +20%.
I ran my own progressive pricing through it ($39 base, +$10 every 5 sales) and it reframed how I think about early months. At $49 I need 41 customers for $2K MRR, but after 40 customers the price hits $119, so only 17/month at that point.
Both free, no signup, no email gate. They join 5 other calculators (churn rate, CAC, LTV, revenue growth, client qualification) at beyondfolder.com/tools.
Building these as an SEO play for my distribution framework. 7 tools live, starting to see relevant queries on page 2 of Google after about 6 weeks. Slow but compounding.
