Reading the RP maths behind your climb
Every ranked match settles into a single net RP swing between −44 and +44 — placement first, then kills, damage and survival on top — so the ladder above is really a map you can read forwards. Since Update 36.1 each division is roughly 100 RP and a full tier spans 400, so take the gap between where you sit now and your target tier's floor, divide by a realistic per-match gain, and you have an honest estimate of how many games the climb is worth. Season 42 pays extra for exactly the thing a booster is good at: back-to-back Top 4 finishes earn a +5 RP streak bonus and back-to-back wins +10, which compounds quickly across a disciplined session. That is also why the calculator prices by band rather than by a flat per-tier fee: each step up costs more per division than the one below it, because a Diamond lobby punishes a mistake at −44 where a Silver lobby forgives it. Reading the table this way tells you what you are buying before you buy it — the net points banked, not a vague promise of "a few ranks".
