Ping & Tickrate Calculator

Frequently Asked Questions

What contributes to total online delay?

Total delay ≈ half ping (one-way RTT) + server tick interval + client frame time + interpolation buffer. Each link adds latency between your input and seeing the result.

How does tickrate translate to milliseconds?

Tick interval (ms) = 1000 ÷ tickrate. A 64-tick server updates every 15.6 ms; 128-tick every 7.8 ms. Lower-tick servers add more delay and coarser hit registration.

What is the interpolation buffer for?

Clients hold a small buffer (often 2 ticks, e.g. ~31 ms at 64-tick) to smooth other players' movement between updates. It improves visual smoothness but adds to your effective reaction delay.

Does lower ping always mean an advantage?

Lower ping reduces your delay, but tickrate, frame rate and interpolation also matter. A 20 ms-ping player on a 20-tick server can feel laggier than a 40 ms player on a 128-tick server.

How This Calculator Works

The delay between pressing a button and seeing the result on screen in an online game is not just "your ping". It is a chain: the round-trip network time (ping/RTT), the time the server waits for its next simulation step (one tick), the time your client takes to draw the next frame, and the deliberate interpolation buffer the client holds so other players move smoothly instead of teleporting between updates. This tool adds those components into a single estimated input-to-display delay in milliseconds, and also expresses it in frames so you can relate it to what you actually feel. It explains why a 20 ms ping can still feel sluggish on a low-tickrate server with a large interp buffer.

Formula / Method

Tick interval = 1000 ÷ tickrate (ms per server simulation step). Client frame time = 1000 ÷ FPS. Interpolation delay = interpolation ticks × tick interval - clients typically buffer one to two ticks of other players' positions. Total estimated delay = ping (full round trip) + tick interval + frame time + interpolation delay. The total in frames = total delay ÷ frame time. This is a first-order model: it captures the dominant additive terms but not jitter, USB polling, render-queue depth, monitor scan-out, or server-side lag compensation, which can each add or subtract a few milliseconds.

Worked Example

Ping 40 ms, 64-tick server, 144 FPS client, 2-tick interpolation. Tick interval = 1000 ÷ 64 ≈ 15.6 ms. Frame time = 1000 ÷ 144 ≈ 6.94 ms. Interpolation = 2 × 15.6 ≈ 31.3 ms. Total ≈ 40 + 15.6 + 6.94 + 31.3 ≈ 93.8 ms, which is about 93.8 ÷ 6.94 ≈ 13.5 frames at 144 FPS. The interpolation buffer (31 ms) is nearly as large as the ping here - dropping to a 128-tick server roughly halves both the tick and interp terms, cutting about 23 ms off the total.

Common Mistakes

Assuming ping is the whole story - tick interval and interpolation often add as much delay as the network itself.

Halving ping for "one way" and then adding it twice - ping is already the full round trip; do not double-count.

Ignoring the interpolation buffer; it is a deliberate, often the largest, single term on low-tick servers.

Confusing tickrate with FPS - the server simulates at tickrate regardless of how many frames your GPU draws.

Expecting this estimate to match a precise high-speed-camera measurement; it omits polling, scan-out, and queue latency.

Tips & FAQ

What lowers delay the most? Usually whichever term is largest for you - a far server (high ping), a low tickrate, or a big interp buffer; this breakdown shows which lever to pull rather than blindly "getting better internet". Does higher FPS help here? A little: it shrinks the frame-time term and reduces jitter, but it cannot compensate for a high-ping or low-tick server. Why does a high-tick server feel snappier? Both the tick interval and the interpolation delay (which is a multiple of the tick) shrink, often removing 20–40 ms versus a 20-tick server at the same ping. Is this my exact input lag? No - treat it as a comparative estimate of the network/sim portion; peripheral polling, the render queue, and display latency add more on top, but those are roughly constant across servers so the differences this tool shows are still meaningful. Why do I get shot behind cover? That is lag compensation working as designed: the server rewinds to where the shooter saw you, so your total delay plus theirs is the window in which a "peeker"s advantage" exists - lowering any term here narrows it for you.
