August 13 planning update
Match the calculator to controls, failures, and boss pressure
Start with the new Tips & Tricks page to identify the first repeatable failure. If the problem is an input or missing prompt, use Controls before changing the build. If the run fails during a breach, open the Bosses hub and enable Boss breach soon here. Only then change one allocation category and compare the next run. This model still does not claim official upgrade prices, boss thresholds, or hidden reward formulas.
Cash Farm
Use this after your checkpoint order is stable. Add throughput gradually and watch whether danger starts outrunning detection.
Boss Prep
Use this before breach pressure or final-threat attempts. Defense and detection should be ahead of raw passenger volume.
How to read the upgrade plan
- Readiness shows whether your current balance can support the selected pressure level.
- Risk rises when passenger volume, danger level, or boss pressure gets ahead of detection and defense.
- Recommended Plan spends estimated upgrade points on the category with the best current improvement value.
- Warnings explain why a speed-heavy or defense-light build may collapse even when cash velocity looks good.
Secure the Airport calculator FAQ
What does the Secure the Airport calculator do?
It reserves Cash for a selected class, then turns your remaining budget, upgrade levels, passenger pace, and danger pressure into an editorial readiness score and suggested next upgrade focus.
Are the calculator numbers official Roblox formulas?
No. The calculator is an editorial planning model. Enter current in-game costs and use the result as a decision aid rather than a hidden formula.
Which upgrade should beginners prioritize?
Beginners usually benefit from scanner reliability and luggage control before increasing passenger throughput.
How should I use the calculator before bosses?
Switch to the boss prep scenario, check whether defense and detection are behind, and stop pushing speed if the risk score is high.
Can the calculator help with fast cash farming?
Yes. Use the cash farm scenario after your scan, luggage, and document checks are reliable enough to handle more passenger volume.
