Specifications. Recommended Delta-V: ~ 6,500 for Orbit and Return. ~ 7,500 for Landing and Return.
Getting an intercept with minmus is harder, because of the smaller SOI and inclination. Once you have an intercept, getting in orbit, landing, getting back to orbit and getting home are easier. All of those things require less dV , lower TWR , and are more tolerant of human error.
Your calculator is 100% correct, you DO need 12000 delta-v to go from Kerbin surface to land on MinMus, and return to Kerbin surface.
With proper aerobraking, a round trip from Kerbin to Duna's orbit and back requires roughly 1700 m/s of delta-v, less than a round trip to any other planet....Interplanetary Travel.BodyDelta-VKerbin~620 m/sDres~820 m/sEve~1080 m/sJool~1350 m/s3 more rows
The Mun's orbit keeps it directly above Kerbin's equator. Because the Mun is tidally locked to Kerbin with a perfectly circular, non-inclined orbit, exactly 50% of the Mun's surface (excluding areas on the edge obscured by the Mun's mountains) is ever visible from Kerbin.

You will need at least 2000ms Delta-V for the orbit and return, you can test this by seeing if your lander is **almost** capable of reaching Kerbin orbit by itself.
Similar to the Mun guide, wait until Minmus is about 4-5 degrees over the horizon (20-40 degrees in the map) to begin your burn. It will appear as a small dot above the horizon. Burn until your apoapsis intersects Minmus' orbit, and (hopefully) you will be caught.
After your ship reaches that Minmus escape point, you'll be independent of Minmus' gravity and are back in orbit of Kerbin. In order to get back to Kerbin, wait until you are at your Kerbin orbit's Apoapsis, point your ship toward your retrograde vector, and wait for your periapsis to sink back into Kerbin.
roughly 4500 m/sReaching a stable orbit around Kerbin is one of the first milestones the player achieves in the game. Achieving such an orbit with a fuel-optimal ascent requires a delta-V of roughly 4500 m/s, the second largest of all celestial bodies with a solid surface after Eve.
Duna has a thin, cool atmosphere with a mass of approximately 3.0×1015 kilograms, a datum level pressure of 6.755 kilopascals (0.067 atmosphere), and a depth of 50,000 meters. Compared to the atmosphere of Kerbin, Duna's atmosphere has 1/15th the mass, 1/15th the surface pressure, and 1/9th the surface density.
To execute this maneuver the player should start in a low Minmus orbit the lower the periapsis to just below the surface in the centre of one of the flats. Proof-of-concept lithobraking has been carried out successfully, without retro-rockets or parachutes, on both the Mun and Kerbin.
