Model decisions before they become expensive.
Every strategic decision has a financial consequence. Hiring, fundraising, cutting costs, expanding to a new market, each path leads to a different financial outcome. RunwayCal's scenario engine lets you test each path and see the impact on your runway, burn rate, and cash position before you commit resources.
You face weekly decisions that affect your financial trajectory. Hire or wait? Cut or invest? Raise or extend? You need to see the consequences of each path before committing. RunwayCal's scenario engine starts from your confirmed data and lets you model any decision with slider-based adjustments, so you get answers in seconds instead of hours. Save up to 3 scenarios, compare them side by side, and share the comparison with your co-founder or board to align on the best path forward.

The challenge
Decisions feel irreversible
Hiring someone takes weeks and costs thousands in recruiting. Letting them go costs months in morale and severance. You can't easily undo a hiring decision, so you need to model it thoroughly before making it. The same applies to signing a lease, launching a new product line, or committing to a long-term partnership.
Spreadsheet scenarios are fragile
You can build a scenario in a spreadsheet, but it takes 2 hours and breaks when you change an assumption. Building 3 scenarios for comparison takes a full day. RunwayCal generates scenarios from your live data with slider adjustments. Build and compare 3 scenarios in 10 minutes.
No connection between scenarios and reality
A scenario is only useful if it's based on your actual numbers. If your baseline is wrong, every scenario built on top of it is wrong too. RunwayCal's scenarios start from your confirmed data, so the 'what if' calculations reflect your real financial position, not an idealized version of it.
How RunwayCal helps
9 pre-computed scenarios from your data
RunwayCal analyzes your current financial position and generates relevant scenarios automatically. 'Grow revenue 10% monthly' shows you reaching cash-flow positive in 17 months. 'Reduce team by 1' shows 0.3 months of additional runway. Each suggestion includes the runway impact so you can quickly evaluate which actions have the most effect. The suggestions update as your data changes, so they always reflect your current situation. One click to explore any suggestion and see the full financial projection.

Slider-based adjustments
Drag sliders to adjust monthly burn, headcount, cash inflows, one-time costs, tool spend, and revenue growth. See the scenario runway update in real time as you move each slider. The output panel shows scenario runway, hypothetical burn, adjusted cash, and cash-out month. Everything updates instantly. No formulas to write, no cells to configure. Move a slider and watch the numbers change. It's financial modeling that anyone on your team can use without spreadsheet expertise.

Compare up to 3 saved scenarios
Save scenarios with descriptive names. Compare them on a single chart showing cash balance projections over time. The comparison table highlights the best and worst values for each metric. See which scenario gives you the longest runway, lowest burn, and latest cash-out date. Toggle scenarios on and off the overlay chart to isolate specific comparisons. Share the comparison with your co-founder or board to align on the best path forward.

Burn sensitivity analysis
Adjust your overall burn rate from -50% to +50% and see how it affects runway. This answers the question: 'How sensitive is my survival to changes in spending?' If a 10% burn increase costs you 2 months of runway, that's important context for every spending decision. The sensitivity analysis shows you the relationship between spending changes and survival timeline. Use it to establish guardrails for your monthly burn and communicate those guardrails to your team.
