How to read this estimate
Comparing a nearby value on the same standard schedule isolates the effect of the pay change without mixing in different working hours.
Comparing nearby annual salaries by month and hour makes a proposed raise easier to evaluate across more than one time period.
A raise can be viewed as an annual difference, a monthly average, or a change in the implied hourly rate. The nearby table holds the work schedule constant so those views remain comparable. If the new role also changes weekly hours, recalculate that schedule instead of attributing the entire difference to salary.
