Calculation note
Pay-raise arithmetic is simple, but the practical comparison is often muddied by pay period, hourly versus annual basis and one-time bonuses. A useful raise record keeps the old rate, percentage, new rate and recurring yearly value visible together.
A raise changes the recurring base
A percentage raise is not only this week’s extra money. It changes the salary or hourly rate used in future pay-period, overtime, budget and negotiation comparisons. That is why the report shows both the immediate increase and the annualised effect.
Hourly and salary raises need different denominators
A salary raise can be compared directly as an annual amount. An hourly raise needs hours per week and paid weeks per year before it can be annualised. Keeping those assumptions visible prevents an hourly result from being overstated.
Bonus money should stay separate
A one-time bonus may be valuable, but it does not usually compound into future base pay. The calculator includes it as a separate comparison so a pay-review note does not confuse temporary and recurring compensation.
