Stability Coefficient
Compare paying more rent for peace and privacy against the hours needed to afford it.
Premium = rent alone − rent with roommate. Peaceful days = 30 − monthly conflicts (roommate scenario). Labor % = premium ÷ monthly income. Under 10% green, under 20% amber, above = magenta.

Before you trust the result
Check the inputs that matter most: dates, rates, units, costs, and any optional fields you skipped. A calculator can only work with the numbers entered here, so use the result as a decision check rather than a final answer when money, health, tax, legal, or safety consequences are involved.
If the result feels surprising, change one input at a time and watch which number moves. That usually shows the real lever behind the decision.

› Is 10% green arbitrary? Trust & accuracy
It's a sane threshold for the sanity premium — under 10% of labor is absorbable; over 20% eats your runway.
