What this means
Lower salary + bonus comes out ahead on after-tax cash, but this comparison only measures the money side of the trade-off.
The take-home gap is about GBP 2,938 a year, or GBP 245 a month.
If the bonuses are uncertain, the more reliable package can still be the safer real-world choice even when the projected net pay is close.
- Bonus certainty, payment timing, and non-cash benefits are not included in this comparison.
- The calculator compares after-tax cash value, not the reliability of a bonus actually being paid.
Lower salary + bonus is ahead by £2,938 of estimated annual take-home pay in this fixed-versus-variable pay comparison.
FAQ
Short answers to the questions that usually matter once you have the first result.
Does this tell me which package is safer?
No. It compares after-tax cash value, not the certainty of a bonus being paid.
What is excluded?
Non-cash benefits, commute, equity, and timing risk are outside this calculator.
Key assumptions and limitations
This compares after-tax cash rather than certainty. Bonus timing, payout conditions, and non-cash benefits still matter when two structures look close on the net-pay numbers alone.
