Decision templates

Every template launches the real engine — no decorative cards. Guided templates open a numeric model with worked example inputs you replace with your own. Frame templates open the simulator with your question pre-filled and name the narrower question the model actually answers, so you can see what is being modelled and what is not before you run it.

Business

Powered by the runway and major-purchase models — seeded Monte-Carlo, evidence gates, honest bands.

Will my cash runway last?Survival probability over your horizon — not a flattering straight line.GUIDEDrunway model Can we afford to hire?Models the full monthly cost against cash survival — not the revenue a hire might create.GUIDEDrunway model What if revenue falls?Downside and stress scenarios are computed on every run.GUIDEDrunway model Equipment purchaseUpfront plus running costs against your buffer — affordability, not the benefit.GUIDEDmajor purchase model Price increase decisionModels the revenue scenarios you state — no model can know your customers’ response.FRAMErunway model Founder salary decisionYour pay is a cost line — see what the runway can carry.GUIDEDrunway model Marketing investmentModels the committed spend against cash; the return is your stated assumption, not a prediction.FRAMErunway model Expansion / new locationModels the upfront and recurring commitment against your buffer — not the new site’s revenue.FRAMEmajor purchase model Debt repayment strategyModels buffer resilience under committed repayments — not a product recommendation.FRAMEmajor purchase model

Work & career

Powered by the career model — buffer survival through an income transition. No fake "success rates": none defensibly exist.

Leave or stay in a job?Models whether your buffer survives the transition — not whether the new role works out.GUIDEDcareer model Accept this job offer?A written offer turns your biggest assumption into a fact.GUIDEDcareer model Start a business?Models whether your buffer survives the ramp — not whether the business succeeds.GUIDEDcareer model Retraining decisionModels training months as negative-income ramp — not your odds of employment after.GUIDEDcareer model Guide: can I afford to change careers?The four numbers that matter, with a reproducible worked example.GUIDE

Money & home

Powered by the major-purchase model — upfront cost plus real running costs against your buffer.

Can I afford this purchase?Car, renovation, any big commitment — buffer survival, honestly.GUIDEDmajor purchase model Move home?Deposit, fees and the new monthly commitment vs your buffer — not a house-price prediction.GUIDEDmajor purchase model Delay or act now?The engine prices what waiting actually changes — with its limits stated.GUIDEDmajor purchase model Compare two commitmentsRun each through the same model; compare the bands, not vibes.FRAMEmajor purchase model Guide: the honest affordability mathsWhy "I can cover the payment" fails, with a reproducible example.GUIDE
Boundaries. LEXUN models financial survivability — it is not a doctor, solicitor or regulated financial adviser, and refuses medical, legal and immigration questions rather than pretending. Crisis language routes to human help (Samaritans, 116 123). Every result shows its uncertainty, its assumptions and the strongest case against itself.
