Why a low payment does not prove a cheap loan

Short answer #

A payment can fall through a longer term, larger upfront sum or balloon. This changes payment timing, not automatically total cost. Compare APR, total payments and remaining balance.

Important variables #

• Loan after upfront payment
• Effective APR
• Term and balloon
• All mandatory fees

Worked example #

€400 for 84 months totals €33,600 while €520 for 60 months totals €31,200, before any balloon and fees. The lower payment can cost more.

Break-even: What changes the result? #

A shorter term usually raises payment but often reduces total interest. An upfront payment reduces the loan but uses liquidity immediately.

Common mistakes #

• Comparing payment alone
• Ignoring the balloon
• Reading a term extension as saving
