Different inputs or rules usually explain the discrepancy. Full reduction to a base number gives the same result for the same digits. Methods that preserve master numbers at intermediate steps can differ.
Find the point of difference
Write both calculations side by side. Are the day, month, and year reduced separately? At which point does reduction stop? Those details make the comparison meaningful.

Life path numbers: meaning and calculationWhich method is correct?
A numerological convention is not an empirically established personality measure. A fair comparison requires an explicit rule used consistently. Do not switch methods simply to obtain a preferred number.
Calculation and method
Use the day, month, and full birth year. For April 12, 1990, the digits add up to 1 + 2 + 0 + 4 + 1 + 9 + 9 + 0 = 26. Then 2 + 6 = 8. This example illustrates basic reduction. Master number cases also depend on the stated stopping rule.
