Will the asset pay for itself?
Financing an asset only makes sense if it earns or saves more than it costs to repay. This calculator gives the monthly payment and the total cost of credit, so you can hold them against what the asset will bring in.
A fridge that lets you sell cold drinks, a vehicle that cuts delivery costs, or equipment that speeds production should generate more each month than its repayment. If it does not, the financing is a drain, not an investment.
