Finance
Finance calculators for runway, burn, cash flow, and valuation planning.
Best for Founders, finance teams, operators, and investors making cash and valuation decisions.
How to use this hub
Finance work usually starts with one of two questions: how much time do we have, or what is the asset actually worth under a stated set of assumptions.
Choose the task that matches the decision in front of you, then use the linked guide or calculator to go deeper.
Quick checks before you compare tools
- Match dates across cash balances, debt balances, share counts, and valuation outputs before comparing scenarios.
- Document which claims, costs, or debt-like items are included so your team can reconcile results later.
- Run downside and sensitivity cases whenever the decision depends on uncertain timing or market assumptions.
Choose a task
Start from the question you are trying to answer, then jump into the calculator or guide that gets you moving fastest.
Cash and operating risk
Use these when liquidity, burn, or debt-service pressure is changing faster than your static forecast.
Estimate runway and burn pressure
Translate burn into actual operating time, then test whether current cash and efficiency targets still give you enough room to act.
Check debt service and downside flexibility
Model payment burden and downside scenarios before you assume the current debt structure is operationally safe.
Valuation and fundraising
Use these when the question is about valuation range, financing mechanics, dilution, or exit outcomes.
Build or challenge a valuation range
Start with the modeling workflow, then move into the calculator that matches whether you need base-case value or sensitivity work.
Model dilution and financing terms
Compare round structure, SAFE and note conversion, and preference outcomes before negotiating or presenting scenarios.
