Introduction: The financial burden of food expenditure on household budget varies according to socioeconomic context, and food cost plays a central role in food choices. Objective: To analyze food acquisition, expenditure share, and food costs within household budgets among Brazilian households, according to income level and geographic location. Method: This ecological study used data from the 2017/2018 Household Budget Survey. Foods were classified according to NOVA system, and total energy availability was estimated using the Brazilian Food Composition Table (TBCA). Per capita daily energy acquisition (Kcal/day) and food costs (R$/day) were calculated for each survey stratum. The impact of diet costs on the household budget (%) was calculated by multiplying daily costs by 30 days. Results: Households in the lowest income tertile and those located in rural areas allocated a greater share of their budget to food expenditures. Although diets were predominantly composed of unprocessed and minimally processed foods, fruits and vegetables accounted for a small proportion of food acquisition. In contrast, ultra-processed foods (UPF) were more frequently acquired by the highest income tertile. Discussion: The high budget burden observed among the lowest-income tertile and rural households highlights food costs as a structural barrier to healthy eating and reveals profound inequities within the food system. Conclusion: Ensuring population health requires making healthy diets more equitable and affordable. Therefore, public policies that promote the fruits and vegetables consumption and discourage the UPF consumption are essential.
