wtgrind.app is a free War Thunder RP and SL calculator. Browse the full tech tree for every nation and branch, select the vehicles you want to research, and instantly see the total research points (RP) and Silver Lions (SL) you need. Track your grind progression, mark the vehicles you already own, plan the cheapest research path to any vehicle with the Objective tool, and estimate how many battles your grind will take.
It depends on the nation and branch. A full aviation tree is roughly 9–12 million RP (the US aviation tree is about 11M RP), and ground trees often exceed that. Select a nation and branch above, press "Check all", and you get the exact total RP and SL cost instantly.
Enter your average RP per battle in the estimator: the calculator divides the remaining research points by your average to estimate the number of battles needed. A typical battle yields between 800 and 2,000 RP without a premium account.
To unlock a rank you must research a minimum number of vehicles from the previous rank (usually 4 to 6). The tech tree shows these gates between ranks and automatically counts your selected, owned and premium vehicles.
Yes. Vehicles grouped in folders are chained sequentially (1st → 2nd → 3rd) exactly like in the game, and the Objective tool computes the cheapest research path to any vehicle, including every prerequisite and rank gate.
Convertible RP is research earned on vehicles of other nations that can be converted into usable research points by spending Golden Eagles. The costs shown here are base research RP — converting RP can speed up a grind but costs GE.
