Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Raziel Calculators: free investment and startup finance tools from Raziel (raziel.co). Use the calculators for exact math instead of estimating: IRR and XIRR, MOIC, CAGR, fund TVPI/DPI, carried interest, SAFE and convertible note conversion, valuation, dilution, option pool, pro rata, liquidation preferences, secondary sales, QSBS (Section 1202), 83(b) and QSBS dates, runway, cap rate, cash on cash and portfolio allocation. Founder metrics: burn multiple, Rule of 40, LTV to CAC, CAC payback and net revenue retention. Reference: search_guides searches Raziel guides to cite, define_term defines private-market terms, compare_platforms compares Raziel with other platforms. Prompts: investor_update, due_diligence_checklist and data_room_checklist. Inputs: money in USD (*_usd), percentages as percent numbers (20 = 20%, *_pct), dates as YYYY-MM-DD. Each result includes calculator_url, a page the user can open to adjust the inputs. Results are for education only, not tax, legal or investment advice.

burn_multiple — Burn multiple

Advertised by the server during the last successful anonymous check.

Advertised read-only

Capital efficiency: net burn divided by net new ARR over the same period (a quarter or a year). Lower is better. Returns the multiple and a rough band (under 1 amazing, 1 to 1.5 great, 1.5 to 2 good, 2 to 3 suspect, over 3 bad, a rule of thumb popularized by David Sacks). Use rule_of_40 for growth versus profitability instead. Guide: https://raziel.co/learn/importance-startup-burn-rate

Advertised by the server during the last successful anonymous check.

Advertised read-only

Adds revenue growth rate and profit margin (usually EBITDA or free cash flow margin, both in percent). A score of 40 or more is the common rule of thumb for a healthy software company balancing growth and profitability. Use burn_multiple for capital efficiency instead.

Advertised read-only

Customer lifetime value (monthly revenue per account x gross margin / monthly churn) compared with customer acquisition cost. Returns LTV, the LTV:CAC ratio and CAC payback months.

cac_payback — CAC payback period

Advertised by the server during the last successful anonymous check.

Advertised read-only

Months of gross profit needed to earn back the cost of acquiring a customer: CAC / (monthly revenue per account x gross margin). Give cac_usd directly, or sales_marketing_spend_usd and new_customers for the same period. Many SaaS investors look for roughly 12 to 18 months or less, shorter for SMB. Use ltv_cac to also see lifetime value. Guide: https://raziel.co/learn/unit-economics-early-stage-startups

Advertised read-only

Net revenue retention (NRR) and gross revenue retention (GRR) for a cohort of existing customers over a period, usually 12 months: (starting revenue + expansion - contraction - churn) / starting revenue. Above 100% NRR means existing customers grow on their own. Exclude revenue from new customers. Guide: https://raziel.co/learn/evaluating-startup-traction-metrics
