FAQ

Senior Full Stack Engineer salary

On a median base salary of $153,370, a Senior Full Stack Engineer at a US SaaS company makes about $12,781 a month, $5,899 every two weeks, or $73.74 an hour over 2,080 working hours a year. The middle half of salaries (25th–75th percentile) works out to $12,000–$13,333 a month. These are base-pay equivalents before tax, and they leave out bonus, commission, and equity.

Expect the lower half of this benchmark. Across 25 verified SaaS Senior Full Stack Engineer salaries, the 25th percentile is $144,000 and the median is $153,370. A Senior Full Stack Engineer at a seed or Series A startup, or at a bootstrapped company under roughly $10M ARR, will often land between those two figures. Base pay typically moves toward and past the $160,000 75th percentile as the company adds headcount and ARR. Those stage bands are a rule of thumb applied to this benchmark, not a breakdown by company size, which the dataset does not report.

Budget for more than base salary. On a median base of $153,370, the fully loaded cost of a US Senior Full Stack Engineer is roughly $191,713–$214,718 per year once employer payroll taxes (~7.65% FICA plus federal and state unemployment), health and retirement benefits, software seats, and equipment are added. That 1.25–1.4x multiplier is a planning rule of thumb applied to the benchmark on this page, not a surveyed cost figure. Commission, bonuses, and equity sit on top where the role carries them. Also budget one-off hiring costs: agency recruiting fees commonly run 15–25% of first-year base, and a new hire takes weeks to months to reach full productivity.
