Spot runway compression before it becomes a crisis.
3-month averaged burn rate, trend direction, payroll concentration, and burn multiple. The metrics that predict survival. You know your burn rate matters, but a single number isn't enough. You need a breakdown of where money goes, how fast the rate is changing, and what it means for your timeline. RunwayCal gives you the composition, the trend, and the impact so you can act before compression becomes critical.
You know your burn rate matters but don't have a clear, continuously updated view. You need a breakdown of where money goes, trend detection for cost creep, and anomaly alerts, all connected to runway impact. RunwayCal gives founders, business owners, and finance teams burn rate management that is deterministic, transparent, and always current. Whether you're pre-revenue or growing fast, burn composition and trend data keep you in control of your financial trajectory.
The challenge
Burn creeps up without warning
A new tool here, a salary increase there. Individual costs seem small, but compounded over months, they compress your runway significantly. You need to see the trend, not just the current number. RunwayCal's burn trend chart shows month-over-month changes with color-coded bars so you can spot the creep before it becomes a problem. What looks like a stable $50K/mo burn might actually be growing at 8% monthly. Catching that early gives you months to correct course.
Know the total but not the breakdown
Your bank shows money going out. But which category is driving it? Is it payroll at 86%? Tools growing faster than expected? Commitments you forgot about? Without a composition breakdown, you're cutting blind. RunwayCal splits burn into payroll, tools, cash commitments, and one-time expenses so you know exactly where to look. That breakdown changes every conversation about cost reduction from guesswork to precision. You cut what matters and keep what generates value.
Cost changes don't connect to runway
You cut a $3,000/mo tool and feel good about saving money. But how many months did that actually buy you? Without connecting costs to runway, savings feel abstract. RunwayCal shows exactly how each cost change affects your timeline. Cut that tool and watch your runway extend by 0.3 months. That's concrete. Now multiply that across every expense decision you make this quarter and the cumulative impact becomes clear.
How RunwayCal helps
Burn composition breakdown
See payroll, tools, and commitments split with donut chart and percentage bars. RunwayCal categorizes every outflow automatically based on your team, tools, and commitment data. The composition updates monthly. Compare this month's breakdown against last month. Spot when a single category is consuming a disproportionate share of your budget. Track how the ratios shift over time as your team grows and tool stack evolves. Use the breakdown to set category budgets based on actual patterns.

Expense anomaly detection
Deterministic rules flag cost spikes: payroll jumps more than 20%, tool spend increases more than 15%, or commitments exceed budget. No AI guessing. The thresholds are mathematical. If payroll went from $80K to $100K in one month, you'll see it flagged with the exact percentage change and the runway impact. These alerts surface in your weekly digest so nothing slips through during busy periods. Catch anomalies the week they happen, not the quarter they compound.

Model cost changes impact on runway
Adjust expense sliders and see how many months change in real time. Test: what if you reduce headcount by 1? What if you cut all non-essential tools? What if you renegotiate a commitment from $3,000/mo to $2,000/mo? Each adjustment shows the new burn rate, new runway, and the delta from your current position. Make cuts strategically, not desperately. Know exactly which changes give you the most runway per dollar saved. Save the scenarios that work and implement them with confidence.

Budget vs actual by category
Set monthly budgets for every burn category. RunwayCal tracks actual spending and flags variances automatically. See which categories are on track, which are over budget, and which are under. The budget runway impact shows what happens if you spend at budget pace versus actual pace. That's the difference between planned discipline and real discipline. Over time, you build a track record of financial control that matters to investors and partners. Budget tracking becomes a competitive advantage, not just an accounting exercise.
