Common questions about the DB function usually involve error handling, result checking, and reuse across multiple cells; this section includes 3 FAQs and a 3-item glossary.
FAQ
What should I do if the DB function returns an error value?
- Check whether
cost,salvage,life, andperiodare valid numeric values. - Confirm that the correct parameter separator is used and that there are no extra spaces or incompatible punctuation marks.
- If the parameters come from cell references, check whether the referenced cells contain text, blanks, or unexpected formatting.
What should I do if the DB result does not match my expectation?
- Review whether the asset cost, salvage value, useful life, and period were entered correctly.
- Check whether the optional
[month]parameter is needed for your scenario. - Recheck the meaning of each parameter in the function guidance, then calculate again.
How can I use the DB function in multiple cells?
- Enter the
=DB(...)formula in the first target cell. - Drag the fill handle or copy and paste the formula into other cells.
- After filling, check whether relative and absolute references behave as expected.
