Getting a written job offer is a milestone, but it is rarely the final number. Most employers build a small slice of negotiating room into the first package, and the salary you actually accept is usually decided in one short conversation. This counteroffer calculator turns that conversation into numbers: you enter the base offer, the salary you researched and want, and the counter you plan to propose, then it shows exactly how big a bump you are asking for, how far you are from your target, and what the difference is worth over time in today's dollars.
The core idea is simple. A higher starting salary does not only pay you more this year. Because raises, bonuses, and sometimes equity are quoted as percentages of base pay, a stronger starting number compounds for every year you stay. Modeling that compounding effect — and discounting future dollars back to today — is what separates a confident negotiation from a guess.
How to Use
- Type the Employer's Base Offer — the annual base salary written in the offer letter. Ignore bonus, equity, and benefits for now; this calculator works on base pay so the comparison stays clean.
- Enter Your Target (Ask) Salary. This should come from market data (Glassdoor, Levels.fyi, Payscale, or recruiter conversations), not from how much you wish you made. A target supported by evidence is far harder for an employer to dismiss.
- Set Your Counter Offer — the number you will propose back. A common starting point is halfway between the offer and your target, rounded to a memorable figure.
- Adjust Expected Annual Raise if you know the company's typical merit increase; otherwise leave the 5% default, which is a reasonable US planning assumption.
- Optionally change the Discount Rate — use the return you could reasonably earn on invested money (often 4%–7%) — and the Comparison Horizon, usually how long you expect to stay in the role.
- Read the result card. The Counter vs Offer Bump tells you how aggressive your counter is; the NPV Advantage Over Horizon converts the lifetime gap into a single, present-day dollar figure.
If you are choosing between two counters, run the tool twice with different Your Counter Offer values. The NPV line will show you how much present value each extra thousand dollars of starting salary actually buys you.
How the Numbers Are Built
Two calculations drive the result. First, the bump you are requesting:
Counter Bump % = (Your Counter − Offer) ÷ Offer × 100
On an $80,000 offer with a $90,000 counter, that is ($90,000 − $80,000) ÷ $80,000 = 12.5%. Asking for more than about 15% over a first written offer is unusual for base salary and can put you at risk of walking away empty-handed; under 5% usually leaves money on the table.
Second, the lifetime value of the gap. If your counter wins, you earn an annual differential that grows each year with the expected raise. Each future year's differential is discounted back to today:
NPV = Σ (Annual Gain × (1 + raise%)^(t−1)) ÷ (1 + discount%)^t
For the $10,000 annual gain in the example, a 5% raise and a 5% discount rate over five years produce an NPV of about $47,619. The same figure without discounting totals roughly $55,256. The gap between those two numbers is the reason future raises matter: a stronger starting base is worth more the longer you stay.
Examples
Example 1 — The textbook counter. The employer offers $80,000, your research says the market is $95,000, and you propose $90,000. The bump is 12.5%, you are 5.3% below your ask, and the counter is worth about $47,619 in present value over five years versus accepting the offer. This is a clean, defensible ask: it sits just above the midpoint, cites market data, and leaves room for the employer to meet you at $88,000–$89,000.
Example 2 — A small counter with a long horizon. An offer of $90,000, a target of $95,000, and a counter of $93,000 looks like only a 3.3% bump. But on a 5-year horizon with a 4% raise and a 5% discount rate, that $3,000 of extra base is worth roughly $13,000 in present value — and it lifts every future percentage raise off a higher base. Small bumps compound.
Example 3 — Executive scale. An offer of $2,000,000, a target of $2,200,000, and a counter of $2,100,000 is only a 5% bump and a 4.5% gap to ask, but the annual gain is $100,000. Over five years with a 4% raise and a 6% discount rate, the NPV advantage is about $454,000. At senior levels the same percentage movements move millions, which is why negotiation effort scales with package size.
FAQ
What is a reasonable counteroffer percentage?
Aim for a counter that is roughly 5%–15% above the written offer for base salary. Countering 10%–12% above an $80,000 offer is normal and expected; countering 20%+ is usually only credible at senior levels or with a competing written offer in hand. The exact number should sit just above the midpoint between the offer and your researched target.
Should I counter above my target?
Not usually. Your target should already reflect the top of defensible market range. Countering slightly above your target can create negotiating room, but if the employer accepts immediately you may discover you left an easy compromise on the table. Most people counter at or just above target and let the employer pull the number down.
How much is a $1 salary raise actually worth?
About $2,000–$3,000 over five years in present value. Each extra $1,000 of starting base on a typical 5-year, 5% raise and 5% discount profile is worth roughly $4,760 in NPV — because every future percentage raise is also calculated off that higher base. Use the NPV line on this page to see your exact figure.
Is the NPV calculation important, or just the yearly bump?
Both matter, but the NPV is what catches people off guard. A $10,000 annual gain sounds like $50,000 over five years; discounted and grown with raises it is around $47,600 in present value. More importantly, raising your base by $10,000 also raises every future percentage increase, which is why starting salary has an outsized impact on lifetime earnings.
What if the employer says the offer is final?
Even when base salary is fixed, there is often room in signing bonus, annual bonus, PTO, remote days, title, review timing, or equity. If base pay truly cannot move, ask for a guaranteed six-month performance review with a written salary adjustment. A promised raise in six months can be worth most of what you wanted today.
Can I lose the offer by countering?
It is rare. Employers who make a written offer want you to accept, and a respectful, data-supported counter is expected. What can cost you the offer is an ultimatum, a demand with no market evidence, or going back and forth repeatedly. Make one clear counter, cite your data, and give the employer room to say yes.
