A salary increment percentage answers only how much gross salary changed. It does not show the new bank credit, annual value, employer contributions or extra work costs. Start with comparable old and new salary figures, calculate the gross change, then rebuild the monthly and annual decision using deductions, benefits and effective date.
Use comparable salary figures
Compare basic salary with basic salary. Do not put an old basic figure against a new package that includes bonus or allowance. Record whether the new amount is monthly, annual, guaranteed or conditional, and whether working hours, location or responsibilities also change.
| Record or input | What to verify |
|---|---|
| Old basic salary | The true comparison base |
| New basic salary | Guaranteed recurring amount |
| Effective date | Months receiving the increase |
| New costs | Commute, time or role expenses |

If the promotion adds transport cost or unpaid travel time, compare those changes separately rather than hiding them inside the percentage.
Calculate percentage and dollar change
Gross increase equals new salary minus old salary. Divide that difference by old salary and multiply by 100 for the percentage. Keep the dollar difference beside it because household decisions use cash, not percentages. Then estimate deductions using the new annual income rather than assuming the entire gross increase reaches the bank.
