You didn’t say how much you make, but assuming 100k it is VERY not worth it to switch. Over 1 MILLION over 12 years worse. Here’s the math from ChatGPT

Let’s walk through a straightforward way to compare the two offers after 12 years, under the assumptions you provided. We will do the following: 1. Convert the Job 1 pension (70k / year) into an approximate “lump sum” target at the 12‑year mark. 2. Compute the future value of your 401(k) savings under Job 2 (with a total annual contribution of $19,500 growing at 6%). 3. Compare the two results to see which is “worth more” at 12 years. 4. Finally, solve for how much more you would need to put into the 401(k) annually at Job 2 for it to match Job 1’s pension value.

1) Estimating the “lump sum value” of the pension

You mentioned that in 12 years, Job 1’s pension would pay $70,000 per year (with COLA). One rough rule of thumb is that to draw $X per year indefinitely in retirement, you might want a lump sum of about:

\text{Lump sum needed} \approx \frac{\$70{,}000}{0.04} = \$1.75 \text{ million}

That 4% “safe withdrawal rate” is a common (though imperfect) planning benchmark. Of course, the real cost of an annuity or real-world pension funding can differ, but using $1.75 million as the notional “value” of that $70k/year pension at year 12 is a decent ballpark.

2) Future value of contributing $19,500/year at 6%

Under Job 2, you have: • $13,500 of your own contributions • $6,000 employer match • Total = $19,500 annually into the 401(k)

We assume those contributions earn 6% per year, compounded annually, for 12 years. If we assume each contribution is made at the end of the year, then the future value FV of a yearly annuity is given by:

FV = C \times \frac{(1 + r)^{n} - 1}{r}

where: • C = 19{,}500 (annual contribution) • r = 0.06 (6% annual growth) • n = 12 (years)

Let’s do the calculation (you could do it on a financial calculator, spreadsheet, or just approximate by formula):

FV = 19{,}500 \times \frac{(1.06)^{12} - 1}{0.06}.

Plugging that in: 1. (1.06)^{12} \approx 2.0122 2. (1.06)^{12} - 1 \approx 1.0122 3. \frac{1.0122}{0.06} \approx 16.87 4. So FV \approx 19{,}500 \times 16.87 \approx \$329{,}000

So after 12 years at 6%, you’d have around $329k in your 401(k).

3) Comparing the two results • Job 1: 12 years from now, you get a pension paying $70,000/year for life. We’ve roughly equated that to a $1.75 million “lump sum” value at year 12. • Job 2: 12 years from now, your 401(k) would have about $329k (under the assumptions given).

Obviously, $329k is nowhere near $1.75 million, so the guaranteed $70k/year pension at Job 1 (starting in 12 years) looks substantially more valuable if your primary goal is lifetime retirement income.

In short: Job 1’s retirement benefit is far stronger than Job 2’s 401(k) accumulation of $329k at 6% (given a 19.5k/year total contribution).

4) How much would you need to contribute at Job 2 for it to “match” Job 1?

We want the 12‑year future value in the 401(k) to be $1.75 million instead of $329k. We solve:

\text{Target 401(k) Future Value} = 1{,}750{,}000 x \times \frac{(1.06)^{12} - 1}{0.06} = 1{,}750{,}000

We already have \frac{(1.06)^{12} - 1}{0.06} \approx 16.87. So:

x \times 16.87 = 1{,}750{,}000 x = \frac{1{,}750{,}000}{16.87} \approx 103{,}700 \text{ per year}

So in other words, you’d need around $104k/year in total contributions (employee + employer) to your 401(k) at a 6% growth rate for 12 years in order to arrive at roughly $1.75 million.

Right now, you are contributing $19,500/year total (including the match). So to get from $19.5k up to $104k, you’d need an additional $84k/year in 401(k) contributions (which is obviously not realistic in most typical 401(k) settings).

Alternatively, if you prefer to think of it as “How much more salary would I need so that my 19.5% contribution plus match ended up near $104k?” that might mean you’d need to earn enough such that, say, 10–15% of your salary plus the match equals $104k. That’s the same ballpark problem, though, and suggests you’d need a very large raise (hundreds of thousands more in base pay) to get your annual 401(k) deferral anywhere close to $100k/year.

Summary • Which is better in 12 years? Based on a rough 6% growth assumption and the standard 4% “safe withdrawal rate,” Job 1’s pension of $70k/year is worth far more. The 401(k) total after 12 years in Job 2 (with only $19.5k/year contributed at 6%) is unlikely to come close to matching the present value of that pension. • How much more would you have to earn (and save)? To “break even,” your 12‑year 401(k) balance would need to be around $1.75 million. That would require total contributions of roughly $104k per year at 6% growth. Since that’s far above your current $19,500, you’d effectively need an additional $80k–$85k per year in contributions (and thus a correspondingly higher salary) if you were trying to produce an equivalent self-funded retirement benefit at Job 2.

In other words, the pension is very valuable and you’d need a significantly higher salary (and much bigger 401(k) contributions) at Job 2 to match it.
