Staying or Switching: The Income Math of a Job Change

Changing employers is often the fastest way to raise pay, and also one of the easiest ways to lose money without noticing: an unvested match left behind, a bonus forfeited a month before it pays, a retirement account cashed out in the move. Staying has its own hidden cost when pay drifts below the market year after year. This chapter compares the two with numbers: why switching often pays more, when staying is the better financial choice, how to handle a counteroffer, and how to leave without leaving money on the table.

Why switching often pays more

Inside most organizations, raises come from a pool set as a percentage of the current payroll. Your raise is a slice of that pool, applied to what you earn now. A new employer has no such anchor: it prices the role at today's market rate to attract the person it wants. When market pay for your skills has risen faster than your employer's raise budget, an outside offer captures the difference all at once.

The Federal Reserve Bank of Atlanta's Wage Growth Tracker splits wage growth into people who changed jobs and people who stayed. In most periods it has shown faster median wage growth for job switchers than for stayers, with the gap widening when the labour market is tight and narrowing when hiring slows. The premium is real but not guaranteed, and it depends on timing.

An offer's headline number also overstates what it adds to take-home pay. The example takes an offer 10% above a current salary.

At $90,000, federal income tax is about $10,970; at $99,000 it is about $12,950, because the extra pay is taxed at 22.0%. Social Security and Medicare taxes and any state tax take more. That is still a real gain, but it should be compared with everything the move changes, not just the salary line. The raise calculator shows the take-home difference with your own numbers.

When staying makes financial sense

Leaving at the wrong moment can cost more than the raise is worth. Before accepting an offer, check what you would give up.

Unvested money. Employer 401(k) contributions may vest over several years; federal rules allow up to three years for all-at-once vesting or up to six for gradual vesting. RSUs and options usually vest on a schedule too, and anything unvested on your last day is generally forfeited. Know the dollar amount that vests in the next six to twelve months.

A bonus or retention payment due soon. Many plans pay only to people still employed on the payout date.

A pending promotion. If a well-supported promotion is weeks away, it may change the comparison, and it raises the base any future employer will start from.

Learning and stability. A role where you are still growing quickly, or an employer that is stable when the job market is weak, can be worth more than a modest pay difference.

Tenure-based benefits. Pensions, extra leave, sabbaticals or retiree health coverage that build with years of service.

A new employer can sometimes cover what you would lose. Signing bonuses and replacement equity grants exist for exactly this, so put the number on the table when you negotiate (chapter 3).

When switching accelerates your career

The outside route deserves serious attention when several of these are true: your pay sits near the top of your range or well below posted ranges for similar roles; your manager cannot describe a path to the next level; your skills have stopped growing; the organization is shrinking or cutting raise budgets; or you have heard "not this cycle" more than once without specific gaps to close. A move can also be the most practical way into a new field or a larger role, because a new employer is hiring for what you can do next, not only for what you did before.

Counteroffers

When you resign, your employer may offer more money to keep you. It can be tempting, and occasionally it is right, especially if pay was the only problem and the new role is a lateral step. But a counteroffer usually raises pay without fixing the other reasons you started looking: scope, management, growth or culture. It can also change how you are seen, as someone who may leave again, which can affect future projects and promotions.

Ask yourself one question before accepting: if they had paid this from the start, would I have looked? If the answer is yes, the counteroffer does not solve the problem.

Tenure, patterns and the job-hopper question

Hiring managers do notice short stays, but they care less about tenure itself than about the story it tells. A series of moves that each brought more responsibility reads as growth. Several stays of under a year with no clear progression reads as risk. Staying long enough in each role to deliver and show a result, often two years or more, keeps your record easy to explain, and the brag document from chapter 4 gives you the results to talk about. Be straightforward about why you moved; a clear, honest reason is more convincing than a defensive one.

Leaving without leaving money behind

Once you decide to go, the timing of your last day and what you do with your accounts matter.

1. Check dates. Vesting dates, bonus payout dates and the date your health coverage ends. Moving your last day by a few weeks can be worth more than a negotiation.
2. Plan health coverage. If the new employer's coverage starts later, COBRA usually lets you keep your old group plan for a period, at full cost. Compare it with a marketplace plan.
3. Keep your retirement savings invested. Leave the old 401(k) where it is if the plan allows it, or move it with a direct rollover to the new plan or an IRA. Cashing out before 59½ generally means income tax plus an additional 10% tax, and it ends decades of tax-sheltered growth.

A balance of $20,000 that stays invested at an assumed 7.0% a year grows to about $108,549 over 25 years with no further contributions. Cashed out instead, it shrinks immediately by taxes and the penalty, and the growth never happens.

4. Leave well. Hand over your work cleanly and thank the people who helped you. Former colleagues are a large part of the network that brings the next opportunity.
