Salary Negotiation Calculator

Calculate first-year compensation change across salary, bonus, equity and benefits.

Compare recurring and one-time elements separately. Enter current base salary in dollars, offered base salary in dollars, annual bonus-value change in dollars, annualized equity-value change in dollars and annual benefit-value change in dollars. At the worked-example inputs, the first-year compensation increase is $25,000. The total first-year compensation change shows what the new offer is really worth compared with your current job. On the example, a $10,000 raise plus $5,000 of bonus, $8,000 of equity and $2,000 of benefits is a $25,000, or 27.8%, increase, worth about $2,083 more a month. It returns first-year compensation increase, percentage compensation increase, monthly gross-value increase.

The formula

Total first-year compensation change = salary increase + bonus change + equity change + benefit-value change

Worked example

First-year compensation increase$25,000
Percentage compensation increase27.8%
Monthly gross-value increase$2,083

Example inputs

Current base salary$90,000
Offered base salary$100,000
Annual bonus-value change$5,000
Annualized equity-value change$8,000
Annual benefit-value change$2,000

How to interpret the result

Comparing a counteroffer against a current offer only makes sense when recurring elements, salary, and one-time elements, a signing bonus, are kept clearly separate, since a large one-time bonus can make a counteroffer look dramatically better in year one while barely changing the ongoing annual compensation that actually compounds over a multi-year career.

Before you rely on it

What to check

Separate the recurring annual compensation change from any one-time signing bonus or similar payment before judging how much a counteroffer actually improved the deal.

The common error

Where people go wrong with salary negotiation calculator

Evaluating a counteroffer's total first-year value without separating out a one-time signing bonus from the ongoing salary change. A large bonus can make year one look much better while the recurring compensation, the part that compounds over a career, barely moved.

Where the inputs come from

Current base salary and offered base salary give the pay change. Annual bonus-value change, annualized equity-value change and annual benefit-value change capture the rest of the package: a higher bonus target, more equity or better benefits such as a larger 401(k) match or lower premiums. Value each item realistically, discounting equity and bonuses that are not guaranteed. Get the offer terms in writing.

Using the first-year compensation increase in a real decision

Use it to decide how much to negotiate for and which items matter: a higher base salary compounds into future raises and bonuses, so it is usually the most valuable to push on.

When the result stops applying

Equity and bonuses are uncertain and often overvalued at the offer stage. Non-financial factors such as flexibility, growth, commute and culture do not appear here. Higher salary can push you into higher taxes, and the cost of living in a new city can offset it. A raise from a job change should also be compared with what you could earn by negotiating where you are.

What to compare it with

Compare multiple offers on the job offer comparison calculator, and see the take-home effect on the take-home pay page. The raise and real wage calculators judge pay changes, and the cost of living calculator adjusts for location. Prepare with market salary data for your role and region.

Frequently asked questions

How much should I ask for in a salary negotiation?

Base salary, since it compounds into bonuses, raises and retirement match. Signing bonuses and equity are also negotiable, and benefits sometimes are.

Should I disclose my current salary?

In some places employers are prohibited from asking. You can redirect the conversation to the market rate for the role instead.
