How banking works
Traditional calculators hand you one number and silently expect 365 identical days — which is exactly why diets die at the first birthday dinner. Banking is the coach's fix: estimate the event's extra calories, shave that amount in small slices off the days leading up to it, and spend the buffer guilt-free. The weekly total — and therefore your rate of progress — is mathematically identical to a perfect flat week. Saving up beforehand also beats “paying it off” afterwards: anticipation feels like discipline; debt feels like punishment.
The presets are honest ranges, not decoration
People are terrible at estimating event calories, so the menu uses realistic midpoints: a restaurant dinner runs roughly 600–1,000 extra once drinks join, pizza night 800–1,200, a full party 1,000–1,500. When in doubt, round up — an over-banked event just means a slightly better week.
The safety rails
The shave is shown as a percentage of your daily target, because “unnoticeable” is relative: 200 kcal is invisible at 2,400 a day and very noticeable at 1,500. Past ~15% the tool says so and suggests more days, a leaner estimate, or extra movement. And no banked day is ever printed below the 1,200/1,500 kcal safety floors — if the full buffer doesn't fit safely, the tool banks what fits and tells you plainly what the unbanked remainder costs (spoiler: a few weeks' patience, not your results).
And if you didn't bank at all?
The most useful number this page outputs may be the perspective line: a 1,000-kcal event, fully unplanned, erases roughly a third of one week's deficit — about 0.13 kg of theoretical fat. The damage was never the pizza; it's the “I ruined everything, restart Monday” spiral that follows. Run the math, eat the slice, carry on. If the event is actually weekly, that's a pattern — build it in permanently with the calorie cycling calculator, and set the baseline from your TDEE and deficit first.
Frequently asked questions
Does one cheat meal ruin a week of dieting?
Arithmetically, no — a 1,000 kcal event consumes roughly 30% of a standard week's deficit, slowing that week slightly. What ruins weeks is the all-or-nothing spiral afterwards. Bank for it, or just absorb it and continue.
Is it better to bank before an event or compensate after?
Before. The math is identical, but psychology isn't: pre-saving frames the event as earned, while post-event slashing feels like punishment and often triggers the restrict-binge loop. This tool deliberately banks forward.
How big a buffer can I safely bank?
Whatever fits above the safety floors (1,200 kcal/day women, 1,500 men) across your banking days, ideally keeping the daily shave under ~15% of your target. Bigger events than that fit better with more days or a little extra movement.
What's the difference between this and calorie cycling?
Banking handles a one-off event; cycling is a permanent weekly shape built around training days. Same invariant — the weekly total never changes — different problem. If your “one-off” happens every Saturday, switch to cycling.
