Sedentary against very active

Sedentary — desk job, no training gives 2,077 kcal/day. Very active — 6–7 sessions/week gives 2,985 kcal/day — a difference of 909 kcal/day more (+43.8%).

The activity multiplier alone moves maintenance calories by hundreds a day.

Questions people actually ask

Does lowering activity level change the answer in proportion?
The two sides differ by 43.8% in the answer. Read the step table below to see which line moves and which does not — that is where a formula stops being a black box.
What is held constant between the two columns?
Everything except activity level: weight, height, age, sex at birth. That is what makes the difference attributable — change two things at once and neither column tells you which one moved the answer.
Can I compare my own two numbers?
Yes, from the address bar: add ?a.activity=… and &b.activity=… to set each side, and a parameter without a prefix sets both at once. The page is computed per request, so any pair works — these two are only the ones worth a link.

Change either side by adding query parameters — ?a.activity=… and b.activity=…. A parameter without a prefix sets both sides at once. Source: Mifflin MD et al., A new predictive equation for resting energy expenditure (Am J Clin Nutr, 1990), NIH — dietary reference intakes for energy
