Somehow related to HP Calculators

Hi Everyone and Happy New Year to all of you !

This thread is not strictly related to calculators but somehow it could be interesting to code the solution
However, if it is not appropriated to be posted here the Administrators can remove it or move it
I'll try to make some examples, I apologize in advance if I'm not making this clear enough

Retention of the people in a company is a key aspect nowadays
We usually give to the best people a sort of bonus at the end of the year, let's say 500 €
The cost over a 6 years period is obviously 6 times the prize (excluding taxes but I'm more on the criteria here)

To motivate people to stay with the company, we want to modify this model toward
a "loyalty model", .i.e. the more you stay the more you gain

That would be something like this (on a 6 years plan)

for the first two years a 500 € pay raise each year
for the 3rd, 4th a 1000 € pay raise each year
for the 5th, 6th a 1500 € pay raise each year

Being a pay raise is sort of cumulative over the years and this change a lot the total company cost

My math is too rusty to get this straight, the question is, at the end of the 6th year what would it be the total of the pay raises ?

Eventually, can this be translated in a program (HP65) where these parameters can be changed
and the result can be foreseen playing with the parameters ?

Thanks in advance !
Take care
