How to Read a Paycheck Stub Line by Line

A paycheck stub is one of the most information-dense documents an employee receives, and most people glance only at the net figure at the bottom. The stub, however, shows exactly where the difference between gross pay and take-home pay goes, and errors in it are more common than many workers assume. Learning to read it line by line turns a piece of paper you file away into a monthly financial check.

You can verify the arithmetic yourself with the percentage calculator and confirm your true take-home rate against any deduction shown on the stub.

The Two Halves of Every Stub

Stubs divide into earnings and deductions. Earnings show gross pay for the period, broken into regular hours, overtime, bonuses, and any reimbursements. Deductions show everything subtracted, split into statutory items the law requires and elective items you signed up for. The net at the bottom is gross minus the sum of deductions.

Reading the stub means checking both halves. A missing overtime line and an extra benefit deduction look very different in the total, but both start as a single wrong entry.

Your Earning Lines

Line	What It Means	What to Check
Regular	Base hours at standard rate	Hours match your timesheet
Overtime	Hours above the threshold, at a premium rate	Rate is the legal multiplier, not base rate
Bonus or commission	Variable or incentive pay	Taxed differently in some cases
Reimbursement	Repayment of a work expense	Usually not taxable; should not be taxed

The overtime line is where errors cost the most. A missing premium, or hours recorded at the base rate rather than the multiplier, quietly shrinks every affected paycheck. If you are unsure whether your hours should attract a premium at all, the multiplier itself is a percentage rule you can check against the percentage calculator.

Your Deduction Lines

Statutory deductions include income tax withholding, social insurance contributions, and any state or local levies. Elective deductions include retirement contributions, health insurance premiums, and any benefit you enrolled in during open enrollment. Statutory lines change when the law changes; elective lines change only when you change them.

A deduction that appears unexpectedly is usually an elective item you forgot you enrolled in, such as a flexible spending account. A new statutory line, by contrast, follows a rate change and should match the published rate for the period.

The YTD Column

Year-to-date figures sit to the right of each line and accumulate from the first paycheck of the year. The YTD column is the single most useful check on the stub because it should be monotonic: each pay period adds to the previous total, never subtracts, and never jumps by more than expected.

Compare the YTD gross against the sum of your gross pay across the year. If they disagree, a period was missed, duplicated, or corrected without your knowledge. Ask payroll for a reconciliation rather than guessing.

Common Errors to Look For

The most frequent mistakes are an out-of-date tax withholding election after a life change, an overtime rate applied to the wrong hours, a benefit premium charged after you cancelled it, and a name or national ID digit transcribed incorrectly. Each is small on a single stub and large across a year.

Check every stub as it arrives rather than at tax time, when corrections become harder. The payroll department can fix an error in the period it occurred; a discrepancy discovered a year later is a much longer process to unwind.

Turning the Stub Into a Habit

Reading a stub takes two minutes once you know the layout. Keep the prior period’s stub alongside the current one, so year-to-date figures can be compared side by side and any line that moved for no reason stands out immediately. A quiet record of your pay history also settles disputes months later, when memory has faded but the paperwork has not.
