How to Use the Vegan Monthly Grocery Budget Calculator
One of the first questions people ask before switching to a vegan diet is whether groceries will get more expensive. This calculator takes your daily intake of tofu, beans, and mushrooms — the core plant-based protein staples — along with your household size, and estimates the monthly grocery cost.
Unit prices here are based on typical US grocery store pricing: roughly $0.60 per 100g of tofu, $0.30 per 100g of cooked beans, and $0.50 per 100g of mushrooms. For a one-person household eating 100g of tofu, 50g of beans, and 50g of mushrooms daily, the monthly grocery cost lands around $30 — often cheaper than a meat-centered diet.
Keep in mind this only covers the cost of protein staples — grains, vegetables, and seasonings are separate. If you lean heavily on meat substitutes or vegan cheese, actual costs will run higher than this estimate. Use this calculator as a reference for your core plant-protein budget rather than a full grocery bill. Prices vary by store, region, and season, so treat these as approximate figures.
Frequently Asked Questions
Basic plant protein staples like tofu, beans, and mushrooms are usually cheaper per 100g than meat, so grocery costs often go down. Costs can rise, though, if you rely heavily on meat substitutes or processed vegan products.
Eating a variety of tofu, beans, and mushrooms can cover your daily protein target with plant sources alone. Pairing grains with legumes helps round out the essential amino acid profile.
