Simple compounding on your inputs. This is not a market-value estimate. It shows what closing a gap in your numbers is worth over time.
Not counted here: employer contributions like a 401(k) match, which are a percentage of base and move with it; equity refreshers that often scale with total comp; the stronger anchor this sets for every future offer; and one more thing money can't chart: negotiating calmly signals you value yourself, and companies typically read that as seniority.

Why one conversation compounds
In tech compensation, almost everything is calculated as a percentage of your base salary. Your annual bonus target is a percentage of base. Employer contributions like a 401(k) match are a percentage of base. And every future raise is a percentage of whatever your base is at the time. That's why a single negotiated lift doesn't stay a single number: it repeats in your salary every year, it widens your bonus every year, and it makes every future raise slightly larger, compounding quietly for a decade. The calculator counts the salary and the bonus and leaves the employer contributions out, which is one of several reasons the figure it gives you is a conservative one.
This calculator makes that visible with plain arithmetic on numbers you choose. It never estimates your market value and never claims what you should earn. That depends on your role, level, and market. What it shows is the mechanical consequence of closing a gap in your own numbers, over one, five, and ten years. Turning that gap into a number you can actually say is the free Ask Number sheet; the words that go around it are, end to end, in the complete system.
How is this calculated?
base_no(t) = B·(1+R)^t · base_yes(t) = B·(1+L)·(1+R)^t · each year's gap is (base_yes − base_no) · (1 + bonus%), summed over the horizon. Every variable is your input. Nothing else enters the math.
Is this a market-value estimate?
No, and it doesn't try to be. Inputs are yours; the math is just math.
