How we calculate
In financing, the installment is fixed (Price table) and the asset is received immediately. In a consortium, the base installment (asset value plus fees, spread over the term) is adjusted once a year by the correction index, and the asset is only received at the contemplation month (draw or bid), which is not guaranteed.
Formula used
Financing: PMT = value × i / (1 − (1 + i)⁻ⁿ). Consortium: base installment = (asset value + fees) ÷ term, adjusted annually.
Custo total = parcela × prazo (ajustada por juros no financiamento, ou por taxas e reajuste anual no consórcio)
Practical example
A R$ 60,000 asset over 60 months: financed at 19% a year, or via consortium with an 18% admin fee, 2% reserve fund and 5% annual correction.
How to interpret the result
Compare the total cost paid at the end of the term in each option. Financing gives immediate access to the asset, while a consortium only delivers it at the contemplation month.
Limitations
A consortium has no interest, but the installment is corrected by an index that varies by contract; here it's simplified as a fixed annual rate. Contemplation timing by draw or bid is never guaranteed.
