FPS Calculator — How Many FPS Will I Get?
Pick your graphics card, processor, game, resolution and preset. The calculator estimates your average FPS, 1% low and frame time from published benchmark data — and tells you whether your CPU or GPU is the ceiling.
Same setup at other resolutions
Estimate, not a guarantee — see the methodology below. Actual results vary with drivers, temperatures, background load and the specific scene being rendered.
How this FPS calculator works
Every estimate starts from a measured anchor: the frame rate a reference graphics card achieves in each game at 1080p on the High preset, aggregated from published benchmark reviews by Tom's Hardware, TechPowerUp and Gamers Nexus during 2024–2025. Your card's estimate scales that anchor by its relative performance index — an RTX 5090 is indexed at 100, and a card indexed at 50 is expected to deliver roughly half the reference frame rate, with esports titles scaling slightly sub-linearly because they lean harder on the CPU at high frame rates. Resolution then applies measured scaling multipliers: 1440p typically delivers about 72% of 1080p performance, and 4K about 42%. Presets scale again — Low at roughly 1.45× High, Medium 1.2×, Ultra 0.78×. Finally the CPU ceiling applies: every processor in the list has a maximum frame rate it can feed in esports and in heavy AAA games, and the estimate is the lower of what the GPU could draw and what the CPU can supply. That last step is the one most calculators skip, and it is why a flagship GPU paired with an old CPU stops gaining in Valorant long before it stops gaining in Cyberpunk.
The 1% low estimate multiplies the average by a per-game ratio drawn from the same reviews — around 0.82 for the steady Cyberpunk 2077 and nearer 0.65 for the spiky Minecraft — because the relationship between average and lows is a property of the game's engine more than of your hardware. All figures assume native resolution rendering with no upscaling: DLSS, FSR and XeSS raise real results above these estimates, by design, since the calculator's job is a conservative planning figure you can trust before spending money, not a best-case marketing number.
Calculators by game
Reading the verdict
The verdict compares your estimate with the monitors people actually own. Sixty FPS satisfies a 60Hz display; 144 FPS feeds the most common gaming monitors; 240 FPS is competitive territory where the monitor stops being the excuse. If your estimate sits just under a boundary — 132 against a 144Hz screen, say — the cheapest fix is usually one preset step or a resolution-scale notch in the game itself, not new hardware. And if you want to verify what your current system and display are really doing today, in your browser, the FPS test and refresh rate test measure it directly.
Frequently asked questions
How accurate is this FPS calculator?
Treat it as a planning estimate within roughly 10–15% for typical systems. It is built from published review benchmarks and stated scaling rules, but drivers, temperatures, memory configuration and the exact scene rendered all move real results. It is designed to compare hardware choices, not to promise a number.
Why does the CPU change my FPS in some games but not others?
Every frame needs the CPU to prepare it and the GPU to draw it; the slower of the two sets the rate. Esports titles at high frame rates are usually CPU-limited, while heavy AAA titles at high resolution are usually GPU-limited. The calculator models both ceilings and shows you which one binds.
Does the calculator include DLSS or FSR?
No — all estimates are native resolution without upscaling or frame generation, deliberately, so the figure is a conservative floor. Enabling DLSS, FSR or XeSS in a real game will raise your frame rate above the estimate, sometimes substantially.
What is the 1% low figure?
The frame rate of the slowest 1% of frames, estimated from the average using a per-game ratio from review data. It predicts how the game feels in its worst moments — the dips — which matter more to smoothness than the average suggests.
Which upgrade should I buy first?
Find which ceiling binds in the games you play: if the calculator says your result is CPU-capped, a GPU upgrade buys little there; if the GPU estimate is the lower number at your resolution, the CPU is fine. That single check prevents the most common wasted upgrade in PC gaming.
