Plant-based diet cost vs omnivore varies by approach. Whole-food plant-based (beans, lentils, rice, vegetables) typically 20-40% cheaper than meat-heavy diet. Processed plant-based alternatives (faux meat, cheese substitutes) can be 20-40% more expensive. Most people's plant-based cost depends heavily on which category dominates.
What the result means
Positive value = plant-based saves money. Negative = costs more. Varies hugely by food choices. Whole-food plant eating saves most; alternative-heavy costs most.
Run it with sensible defaults
Using weekly meat/fish spend of 40, plant replacement weekly of 25, percentage switched of 100%, the calculation works out to 780.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Weekly Meat/Fish Spend, Plant Replacement Weekly, and Percentage Switched — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
How the math works
Weekly cost difference × switched fraction × 52 weeks. Positive value means plant-based saves money. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Why run the calculation
Utility bills creep. Small annual increases stack into meaningful differences over a decade. Running this once a year and switching providers when the gap widens is one of the easiest ways to keep household costs in check.
What this doesn't capture
Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.
