How much will DLSS / FSR boost your FPS?
Find out how many FPS DLSS, FSR or XeSS upscaling adds in Quality / Balanced / Performance modes at your resolution.
What you enter: FPS without upscaling, CPU limit, resolution
What you get: FPS in Quality / Balanced / Performance
Open →
Do you have enough video memory (VRAM)?
Calculate how much video memory you need for your resolution, texture settings and ray tracing. Find out whether you will run out of VRAM.
What you enter: resolution, textures, RT, frame rate
What you get: VRAM needed, GB
Open →
How much does 1 FPS cost? Upgrade value calculator
Compare graphics cards by cost per frame. Find out which upgrade gives more FPS for your money.
What you enter: price and FPS of two graphics cards
What you get: cost per 1 FPS, upgrade value
Open →
What FPS do you need for your refresh rate?
Calculate how many FPS your monitor actually uses and whether you are losing frames. Match the refresh rate to your graphics card.
What you enter: monitor refresh rate, current FPS
What you get: required FPS and headroom
Open →
Field of view (FOV) calculator
Convert the field of view (FOV) when switching between 16:9, 21:9 and 32:9 so the image does not look stretched or squeezed.
What you enter: aspect ratio, vertical/horizontal FOV
What you get: FOV for another monitor
Open →
How much electricity does your PC use?
Calculate the real power draw of your gaming PC and the electricity cost per month and year at your rate.
What you enter: GPU and CPU TDP, hours, electricity rate
What you get: kWh and cost per month/year
Open →
What bitrate should you stream at?
Pick the best bitrate and codec for streaming on Twitch or YouTube for your resolution, FPS and internet speed.
What you enter: resolution, FPS, codec, platform
What you get: bitrate, kbps
Open →
eDPI and sensitivity conversion calculator
Calculate your eDPI and transfer sensitivity between games (CS2, Valorant, Apex) while keeping your usual arm movement.
What you enter: DPI, sensitivity, game
What you get: eDPI and sensitivity transfer between games
Open →
How to squeeze out the FPS you need?
Find out how much extra performance you need for your target FPS and which settings or technologies will provide the missing frames.
What you enter: current and target FPS
What you get: what to change: settings, upscaling, upgrade
Open →
What the calculators compute: the median catalogue GPU as an example
Average FPS of catalogue GPUs by resolution (median over 1,927 models with measurements, high settings) — the basis for the "FPS for refresh rate" and "Target FPS" calculators.

In short
How accurate are the FPSHQ calculators?
The calculators use open formulas with coefficients from the FPSHQ database (1,927 GPUs with measurements). The result is an estimate: real FPS depends on the CPU, settings and driver version. For an exact measurement use the FPSHQ app.

Frequently asked questions
How accurate are the FPSHQ calculators?
The calculators use open formulas with coefficients from the FPSHQ database (1,927 GPUs with measurements). The result is an estimate: real FPS depends on the CPU, settings and driver version. For an exact measurement use the FPSHQ app.
Where do the DLSS/FSR gain coefficients come from?
From the ratio of the internal render resolution to native (Quality ≈ 67%, Balanced ≈ 58%, Performance ≈ 50% linear scale), adjusted for CPU-bound scenarios. NVIDIA and AMD describe upscalers the same way in their documentation.
Which calculator should I use if a game stutters?
Start with "Target FPS" — it shows how far the GPU falls short; then "DLSS/FSR" — how much upscaling will give; if VRAM is short — "VRAM". For an upgrade — "Cost per frame".
Do I need to sign up?
No. All calculations run in the browser. An account is only needed to save "My PC" and get personalised results across the site.
Methodology and sources
This page uses the FPSHQ database: the GPU and CPU catalogue with synthetic benchmark scores, official game system requirements, FPS measurements from users of the FPSHQ app and the FPSHQ performance model. Calculated values are estimates, not a measurement of your exact configuration: the real result depends on drivers, settings and the rest of the hardware. More about the methodology →
