Financial calculators might give incorrect results due to several factors like incorrect inputs, user error, battery issues, malfunctioning buttons, firmware bugs, wrong settings, calculation errors, incorrect format, device damage, or being in the incorrect mode.

Starting with the simplest explanation, user error or incorrect inputs could be the reason behind the problem. You might have entered the wrong numbers or used the wrong functions. This is a common occurrence especially among new users who are not yet familiar with the specific operations of financial calculators.

Battery issues can also affect the performance of your calculator. Weak or dying batteries might not provide enough power for the device to function properly, leading to errors. Similarly, if there are any malfunctioning buttons, they could lead to incorrect data entry and thus, wrong results. In more serious cases, your calculator might be damaged. For instance, if it was dropped or exposed to water, some internal components might have been affected causing it to give wrong answers.

Firmware bugs can cause calculation errors. The software running on your calculator might have some faults that could result in wrong computations. This might require a software update or, in some instances, the intervention of a professional to rectify.

The calculator can also be set in an incorrect mode which would affect the accuracy of its computations. Some calculators have various modes for different types of calculations. If the calculator is set to the wrong mode, it could be using the wrong formula for your computations.
