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 and assists 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 harder than a Silver one — the −44 to +44 swing dates from Season 36, and Season 42 has since reduced RP losses at the higher tiers without restating that range. 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".
