Frequently Asked Questions
Everything you need to know about Saasly
Yes — free forever. No signup, no credit card, no paid tiers, no trial. Saasly is a community resource for bootstrapped SaaS founders. The calculator, glossary, benchmark library, and printable cheatsheet are all open and free to use.
24+ SaaS metrics: MRR, ARR, ARPU, gross margin, CAC, ROAS, customer and revenue churn, NRR, GRR, Quick Ratio, Magic Number, payback period, LTV, LTV:CAC ratio, CLV, trial-to-paid conversion, activation rate, DAU, MAU, DAU/MAU ratio, CTR, CSAT, NPS, and more — calculated across three months with trend analysis per metric.
No. The calculator runs entirely in your browser — numbers you enter never leave your device. No accounts, no database, no tracking. Close the tab and the data is gone.
Five — SaaS B2B, SaaS B2C, Mobile Subscription, Fintech SaaS, and E-commerce SaaS — each split across three stages (early, growth, scale). 98 dedicated benchmark pages in total, with P25, P50, and P75 percentile bands per metric.
Synthesized from public sources: David Skok's SaaS Metrics 2.0, Adapty's 2025 mobile subscription report, OpenView's 2024 SaaS benchmarks, ChartMogul's 2024 segmentation data, and industry consensus reports for the vertical SaaS bands. Every benchmark page lists its source.
Not currently — Saasly is a calculator + reference library, not a tracking platform. Plug in numbers you already pull from Stripe, ChartMogul, Baremetrics, or your own dashboard. For full automated tracking, the comparison pages cover when each paid tool makes sense.
