If matter is a form of energy, and the total energy of the universe must stay the same, what happens when matter goes into a black hole? Because obviously no form of energy can escape. Or is the universe losing matter?

Matter is not lost when it goes into a black hole. The total mass & energy of the universe remains constant. The only thing that happens is that the mass that goes into a black hole gets "trapped" there.
However, there may be a way for it to get out according to Stephen Hawking. Black Holes may be able to radiate energy (The Hawking Radiation) & thereby gives off energy or particles. The Hawking Radiation comes about when a quantum fluctuation in the vacuum creates a particle & an antiparticle near a black hole. Normally, they come toegether & disappear but if one of the pair gets sucked into Balck Hole, the other particle radiates away.

I assume by matter you mean mass structures. Its the power from space that is needed to form a mass structure. If it its done in a certain amount of time it would have used a particular amount of energy to form the Structure.
So Energy is a phenomenon which is a function of the product of a quantiy of moving mass and the square of the velocity at which it moves.
So mass is not a form of energy it is a strucure (all atoms are structures)There is a difference between mass , Energy and Power.
The total energy and mass of the Universe would stay the same if It is a closed containment with restrains.You are correct on that point.
What escape out of stars is radiation in the form of micromass moving at various frequencies.
If There would exists by definiton a so called black hole which would absorb mass radiation and increase in mass as it does so,It would not change mass content of the Universe.Provided that the black hole would have some kind of purpose or use.
So far we find a purpose for Galaxies and Star and we have not found a purpose for black holes.Above all it does not suck the all energy of the Universe. A mass in order to be contained into a volume no matter what density requires and external pressure to hold it together. So a Back hole if they exist should follow the same Gravitational power of Space rules.Note the total mass of the Universe is very roughly by assumtion and aproximation in the order of !0 ^53 kg.The mass of our Galaxy ,the Milky Way, is in the order of 10^42 kg. The mass of the so called Black hole postulated By Physics are basically minute.So How can it be said , its soaking all the mass of the Universe. The calculated average density of a black hole Within Schwartzchild's Radius can have a density as low and much below that of water.
So it is needed to know what is the purpose of Black hole ? Are they real or just The by product of Einstein's Field equation.

Universe isn't OBSERVED to be losing matter through black holes. Lose matter is just being collected together in one space, this happens for normal stars, as well as black holes.
Parts of question quite insightfull. Just about everything can be described as a form of energy, and SHOULD get "stuck" in a black hole. Hawkins radiation predicted to escape, so it would have to excepted (I don't know if it has been observed/proved)
IF gravity is treated as a type of energy it too must be excepted, otherwise we couldn't have the evidence which "implies" the location of black holes. Understanding how gravity CAN escape might lead to insights into HOW it works.
The assumption that total mass/energy of the universe is constant might not be right. Heard somewhere that the speed of light in vaccuum might actually vary over LONG periods of time. c^2 is "exchange rate" in e/m=c^2 so the total mass/energy of the universe MIGHT fluctuate.

According to some scientists black holes sometimes eject a huge beam of energy on both sides of it ( assuming that a black hole is round) so that might be the energy. Now I know you said that no energy can escape a black hole the oxymoron is that though it is true we are able to detect them some how.

matter is never compleatly destroyed only changed in status the matter that is sucked in to a black hole is only condensed in to a more sub atomicly heaver substance the real question is how dose the universe deal with the forces of constant black hole degredation on the density of time and space

your be counted won,t be neglected ..many things enter a black hollow and the universe is changeless ,.individually i don,t have faith in parallel time universes , in basic terms dimensional universes, even however if there have been time parallels i might desire you entering stated black hollow might end your self interior the destiny in any different case in case you went to the previous you may might desire to be so careful ...even talking to somebody might desire to regulate , a minimum of the historic past of our planet ,,..i like to have faith even however gravity in a black hollow is asserted to weigh down planets to mere atoms , that perhaps the different ingredient of a black hollow or computer virus hollow might yield many extra secrets and techniques to our very life.

What a tremendous question. Far too good for my feeble brain. Don't the laws of physics start to break down as you approach a black hole????

Why should it compensate ?
The mass is still there. The BH is still part of the same universe.
