How to Compare Software Engineer Job Offers (2026 Calculator)

To compare software engineer job offers, model each one year by year for four years: base salary, expected bonus, sign-on cash, and the equity that actually vests each year, including refreshers. Then discount private equity for risk and score non-financial factors with fixed weights. The best offer is the one that wins on risk-adjusted four-year compensation and on the things you care about, not the one with the biggest headline number.

Recruiters quote total compensation as a single annual figure. That number hides vesting schedules, one-time cash, and equity that may never be worth what the offer letter suggests. This guide gives you a repeatable model, a worked three-offer example, and a scorecard you can copy into a spreadsheet tonight.

Key Takeaways

• Compare four separate years, not one average. Back-loaded vesting and sign-on bonuses can make year 1 and year 4 look very different for the same "total comp."
• A dollar of public RSUs is not a dollar of startup options. Discount private equity by stage, then account for strike price, dilution, and liquidation preferences.
• Refreshers decide years 3 and 4. Model a conservative refresher estimate instead of ignoring them or assuming the best case.
• Score non-financial factors with weights you set before you look at the offers. Fixed weights keep you from rationalizing the exciting choice.
• Put a price on the gap. If the lower-paying offer scores higher, compute how much per year you are paying for that difference and decide if it is worth it.
• Most exploding offers bend. Ask for a short extension with a specific date before you accept under pressure.

What Counts as Total Compensation?

Total compensation (TC) is every form of pay you receive from an employer in a given year. For software engineers it usually has five parts, and each one carries a different level of certainty.

Benefits also count. A 401(k) match, an ESPP discount, and health premiums can add several thousand dollars a year. Add them as one line per offer.

Watch the sign-on clawback. Many sign-on bonuses must be repaid, fully or pro rata, if you leave within 12 to 24 months. That cash is real, but it also reduces your flexibility in year 1.

RSUs vs Stock Options vs Private Equity

Equity is where offers diverge the most, so you need to know exactly what kind you are being offered before you can value it.

RSUs (restricted stock units) are promises to deliver shares as they vest. At a public company, each vested RSU is worth the current share price, and you pay nothing to receive it. In the US, vested RSUs are taxed as ordinary income at vest, and employers often withhold federal tax at the flat 22% supplemental rate on amounts under $1 million, which can be lower than your actual bracket.

Stock options give you the right to buy shares at a fixed strike price. They only have value if the share price rises above the strike. You pay to exercise them, and taxes depend on the type:

• ISOs (incentive stock options) have no regular income tax at exercise, but the spread can trigger alternative minimum tax (AMT). Holding the shares more than two years from grant and one year from exercise can qualify the gain for long-term capital gains treatment.
• NSOs (non-qualified stock options) are taxed as ordinary income on the spread at exercise.

Private-company RSUs are common at late-stage startups. They often use double-trigger vesting, meaning shares are not delivered (or taxed) until both the time-based vesting and a liquidity event such as an IPO or acquisition have happened. Until then, you cannot sell them.

Ask these questions about any startup equity offer:

1. How many shares or options, and how many shares are outstanding in total? A share count without the denominator tells you nothing.
2. What is the strike price, and what was the last 409A valuation?
3. What was the price per share in the last preferred round?
4. How long is the post-termination exercise window? The standard is 90 days, and ISOs generally lose ISO tax status if exercised more than three months after you leave. Some companies offer longer windows.
5. Is early exercise allowed? If so, an 83(b) election must be filed with the IRS within 30 days of exercising, which can reduce future taxes but means paying upfront for shares that could become worthless.

If your offer includes options or private RSUs, a one-hour session with a tax professional who knows startup equity is usually worth the fee.

How Do Vesting Schedules and Cliffs Change an Offer?

A vesting schedule is the timeline on which your equity grant becomes yours. Two offers with identical four-year grants can pay out very differently depending on how that grant is spread.

The common patterns, based on self-reported offers on sites like levels.fyi:

Vesting policies change, so confirm the exact schedule in writing with your recruiter. Our salary negotiation guide covers how companies use sign-on bonuses to smooth out back-loaded schedules, and which parts of the offer you can move.

A cliff is a waiting period before any equity vests. The usual setup is a one-year cliff: zero vesting for 12 months, then 25% at once. If there is a real chance you leave in year 1, for example because of a planned relocation or an uncertain visa situation, treat pre-cliff equity as worth zero in your model.

How to Discount Startup Equity for Risk

Startup equity should be discounted because most of its value depends on an exit that may never happen, and because your common stock sits behind investors' preferred stock. A startup offer vs big tech offer comparison is meaningless until you apply that discount.

Start by calculating the paper value correctly:

Paper value of options = number of options x (last preferred price per share - your strike price)

That formula already overstates value. Preferred shares carry liquidation preferences, so in a modest acquisition investors get paid first and common holders can receive far less than the preferred price suggests. Future funding rounds also dilute your percentage.

Then apply a risk factor. There is no industry standard; the ranges below are a rule of thumb used in this model, not a statistic:

If you want more rigor, build scenarios: estimate a probability for failure, a modest exit, and a strong exit, and calculate the expected payout to common shareholders in each. Either way, write down your risk factor before you compare offers, so you do not adjust it to justify a favorite.

The final step is liquidity. A tender offer or secondary sale program lets employees sell private shares before an IPO. Ask whether the company has run one and how often. Equity you can partly sell is worth more than equity you cannot touch.

Build a 4-Year Total Compensation Model

A 4-year model is a table with one row per offer and one column per year, where each cell contains the cash and equity that actually reach you in that year. It is the core of any offer comparison spreadsheet.

Here is a small total compensation calculator in Python you can adapt, or translate into spreadsheet formulas:

def four_year_tc(base, bonus_pct, grant, vest, sign_on,
                 refresher=0, refresher_years=4, equity_factor=1.0):
    years = []
    for y in range(4):
        equity = grant * vest[y] * equity_factor
        equity += y * (refresher / refresher_years) * equity_factor
        cash = base + base * bonus_pct + sign_on[y]
        years.append(round(cash + equity))
    return years, sum(years)

offer_a = four_year_tc(195_000, 0.10, 360_000, [0.25] * 4,
                       [30_000, 0, 0, 0], refresher=60_000)
offer_b = four_year_tc(185_000, 0.0, 400_000, [0.05, 0.15, 0.40, 0.40],
                       [60_000, 45_000, 0, 0])
offer_c = four_year_tc(175_000, 0.0, 600_000, [0.25] * 4,
                       [0] * 4, equity_factor=0.25)

The refresher line assumes one grant of the same size at the end of each year, each vesting evenly over four years. In a spreadsheet, the same logic is one column per year with separate rows for base, bonus, sign-on, initial grant, and each refresher grant.

Keep assumptions simple and visible: flat base, target bonus, current share price, conservative refreshers. The goal is a fair comparison, not a forecast.

Worked Example: Comparing Three Offers

This example uses hypothetical numbers in the general range of senior engineer offers seen in public self-reported data on sites like levels.fyi. Your numbers will differ; the method is what matters.

• Offer A, public big tech (even vesting): $195,000 base, 10% target bonus, $360,000 RSUs over 4 years at 25% per year, $30,000 sign-on, and an assumed $60,000 refresher each year from year 2.
• Offer B, public company (back-loaded vesting): $185,000 base, no bonus, $400,000 RSUs vesting 5/15/40/40, $60,000 sign-on in year 1 and $45,000 in year 2. No refreshers modeled.
• Offer C, Series B startup: $175,000 base, no bonus, 40,000 ISOs with a $5 strike and a $20 last preferred price, one-year cliff then monthly. Paper value is $600,000; risk factor 25%.

Three things stand out. First, Offer B has the largest public-company grant, yet it is the lowest public offer over four years, and its first year is about $70,000 behind Offer A. Second, Offer C looks competitive on paper, nearly matching Offer A. Third, once the startup equity is discounted, Offer C trails Offer A by $488,000 over four years, or about $122,000 per year.

Exercise cost also matters for Offer C. Exercising all 40,000 options at a $5 strike costs $200,000 in cash, plus possible AMT. If you leave before an exit and your window is 90 days, you may have to choose between paying that or walking away from vested options.

The Non-Financial Scorecard

A non-financial scorecard is a weighted list of the things money does not capture, scored the same way for every offer. Set the weights before you score anything, and make them sum to 100.

Each score is 1 to 5. The weighted score is the sum of weight times score, divided by 100.

How to fill it in honestly:

• Manager and team: ask to talk with your future manager and one teammate before you decide. Ask how projects get assigned, how promotions happened recently, and what the on-call load looks like.
• Level: a higher level at one company can be worth more than extra money at another, because future raises and refreshers scale with level. Our staff engineer interview guide explains what the jump to senior and staff usually involves.
• Stability: look at funding runway, recent layoffs, and how dependent the team is on one product. If you have been through a layoff, the laid-off engineer job search guide is a reminder of why this weight deserves respect.
• Visa: for engineers on a work visa, sponsorship policy and the company's track record can outweigh everything else. See our guide to H-1B sponsorship for software engineers.

How to Make the Final Decision

The decision rule is simple: put a price on the scorecard gap. When one offer wins on both money and score, take it. When they split, divide the money gap by the score gap and ask whether that price is acceptable.

In the example, Offer B loses to Offer A on both four-year money and score, so it drops out. Offer A beats Offer C by about $122,000 a year in risk-adjusted pay, while Offer C scores 0.35 points higher. Choosing C means paying roughly $122,000 a year for more growth, scope, and mission, with a real chance that the equity ends up worth its full paper value or more.

That can be the right call, especially with savings, low fixed costs, and early-career years where scope compounds. It is a worse call if you need predictable cash or have visa risk.

Before you sign, take the best competing numbers back to your preferred company. The negotiation guide has email templates for using a competing offer without burning goodwill, and if you still have loops in progress, our job search strategy guide covers how to line up timelines so offers land together.

How to Handle Exploding Offers and Deadlines

An exploding offer is an offer with a short acceptance deadline, often a few days to a week, meant to stop you from collecting competing offers. Deadlines are common, but many are softer than they sound.

Ask for an extension with a reason and a specific date:

Hi [Recruiter],

Thank you again for the offer. I'm genuinely excited about the team.
I'm finishing final rounds with two other companies and want to make a
decision I can fully commit to. Would it be possible to extend the
deadline to [specific date, about 1-2 weeks out]? I'm happy to share
updates as soon as I have them.

Thanks,
[Name]

Some practical rules:

• Ask early. Request the extension as soon as you receive the offer, not the day before it expires.
• Speed up the other side. Tell your other companies you have an offer with a deadline. Many will accelerate. Our article on how long FAANG interview processes take shows which stages can usually be compressed.
• Expect less flexibility for new grads. Campus offers often have firmer deadlines tied to hiring cycles. The new grad interview guide covers that recruiting calendar.
• Read a hard refusal as data. A company that will not move a few days for a final decision may be similarly rigid after you join.

Never accept an offer you plan to back out of. Recruiters move between companies, and reneging follows you.
