A capo on the 3rd fret raises every string by 3 semitones (minor third). You keep playing the shapes you know; they just sound higher. With the capo on the 3rd fret a C shape sounds as E♭, a G shape as B♭, a D shape as F and an Em shape as Gm.
The calculator above is set to capo 3. Type the shapes you play to see the real chords, or switch to “Play in a key” to find the best capo for any key.

Keys with capo 3
Every family of open shapes moves together. C shapes (C, F, G, Am) give E♭ major: E♭, A♭, B♭, Cm. G shapes (G, C, D, Em) give B♭ major: B♭, E♭, F, Gm. D shapes (D, G, A, Bm) give F major: F, B♭, C, Dm. A shapes (A, D, E, F♯m) give C major: C, F, G, Am. E shapes (E, A, B, C♯m) give G major: G, C, D, Em. Am shapes (Am, Dm, E7, F) give C minor: Cm, Fm, G7, A♭. Em shapes (Em, Am, B7, C) give G minor: Gm, Cm, D7, E♭. Dm shapes (Dm, Gm, A7, B♭) give F minor: Fm, B♭m, C7, D♭.
When capo 3 is the easiest choice
Out of every major and minor key, capo 3 is the calculator’s first choice for E♭ major (with C shapes: C, F, G, Am); B♭ major (with G shapes: G, C, D, Em); C minor (with Am shapes: Am, Dm, E7, F); G minor (with Em shapes: Em, Am, B7, C).
How capo 3 sounds and feels
Up to the 3rd fret the guitar still sounds full, and the frets are slightly closer together, which makes stretches easier. It is the most popular range for singers who want a song a little higher. The strings now vibrate over about 84.1% of their open length, so every note is 18.9% higher in frequency: the low E string sounds as G.
Put the capo straight across, just behind the 3rd fret wire (not on top of it), and tight enough that every string rings without buzzing. Then retune if needed: a capo can pull strings slightly sharp.
