A loan comparison becomes meaningful when both offers are intended to solve the same problem. Different amounts, payout durations or repayment assumptions can reverse an apparently clear ranking. Start with a comparison case of your own and apply it to every offer.
Own the comparison assumptions
Record the amount actually needed each month, the number of payout months and the planned start of repayment. Add a manageable future monthly commitment based on a cautious budget. Do not assume an unusually high salary simply to make an offer look affordable. Where future income is uncertain, calculate several understandable versions.
Suppose an invented funding gap is €220 for ten months. That is €2,200 of required money before financing costs. An offer paying more or continuing for longer does not automatically meet the same need. Ask for a calculation based on your case, or clearly flag where a product cannot match it.
Use a table with several outcomes
Compare more than the instalment. Include usable money during study, ongoing interest, expected total repayment and the time until the final payment. A longer term can reduce the monthly burden while increasing overall cost. Both effects matter; no single figure decides what fits every situation.
Add columns for changes: can payouts be reduced, what rules apply to extra repayments, and what happens if study is interrupted? Use the contract information rather than a broad claim on a comparison website. Flexibility is useful only when its conditions and costs fit the particular case.
Keep uncertainty visible
Identify variable rates and the limitations of each cost illustration. Two offers can show the same payment today while responding differently to later changes. Run an additional calculation with higher costs. It tests affordability rather than claiming to forecast the market.
Save the dated versions you compared and list unresolved questions beside them. If an offer changes, update its row before making a decision. For an advice appointment, an incomplete table with honest labels is more useful than a seemingly exact result based on hidden assumptions. Include concrete alternatives that do not require new borrowing too: a useful comparison may show that the original loan amount can be reduced.
