How this site stays free
MustangCalculators has no paywalls, no login walls, and no subscription fees. Every tool — compression ratios, gear calculations, quarter-mile estimates, injector sizing, and more — is free to every Mustang owner who needs it. We keep the servers running and the calculators updated through a combination of advertising partnerships and the generosity of readers who choose to support the site directly.

Our advertising partner
Display ads on MustangCalculators are served through Monetag, a reputable advertising network used by publishers worldwide. Monetag maintains quality and safety standards for the ads it serves. We chose Monetag specifically because their network does not serve the low-quality, deceptive, or malicious ad categories that plague lesser ad networks. If you ever see an ad that seems out of place or inappropriate for this audience, please contact us — we take ad quality seriously.
Some links on this site are affiliate or sponsored links. These are always disclosed where present. When you see a link marked "sponsored" or a note like [ Click to see how we earn ], that is us being upfront about how the site generates revenue. Clicking those links costs you nothing extra and helps keep every calculator free.
Support us directly
If you find this site useful and want to help keep it alive, you can buy us a coffee on Ko-fi. No account required, no pressure — just a direct way to support the tools, the hosting, and the memory of Scott G. Clayton that this site is built around.
Every contribution goes directly toward server costs, tool development, and keeping this website alive and free for every Mustang owner who needs it.
Advertise with us
MustangCalculators serves a focused audience of Mustang owners, restorers, racers, tuners, and DIY builders actively looking for technical tools and reference data. This is not a general automotive audience — these are hands-on enthusiasts who spend money on parts, tools, and services.
We accept direct advertising placements from brands and businesses that are a genuine fit for this audience. If you are in the automotive parts, tools, restoration, performance, or related space and want to reach Mustang owners directly, we would like to hear from you.

Editorial independence
Advertising and affiliate relationships have zero influence over calculator formulas, paint-code data, technical accuracy, or editorial recommendations. The tools on this site are built to be correct — not to serve an advertiser's interest. Paid relationships are disclosed where present.
Placement standards
We reserve the right to reject any ad category, creative, or offer that does not meet our standards for audience safety, legal compliance, brand fit, or technical quality. Categories we do not accept include adult content, gambling, payday lending, and anything we would not want shown to a teenager working on a Mustang in their dad's garage.
