Lord Krsna is the Supreme Personality of Godhead and cause of all causes. Krsna is the ORIGINAL Form of God from whom ALL His Visnu and Narayana forms expand from. This means the only difference between Srimati Radharani and Lord Balarama, is Lord Krsna IS the Supreme Personality of Godhead and ORIGINAL cause of all causes who has 4 extra qualities than both Radharani and Balarama.

Lord Krsna has 64 qualities in full, or 100% of His own personal attributes that other expansions only partially have.

The percentages of Krsna's 64 qualities that others have mathematically work out as follows-

Visnu-tattva (headed by Balarama) and Visnu-"sakti"-tattva (headed by Radharani) both have 60 qualities or 93.75% of Krsna's qualities.

So how much is 60 qualities out of 64 qualities written as a percentage exactly?

Convert fraction (ratio) 60/64

Answer: 93.75%

Siva-tattva has 55 qualities- How much is 55 out of 64 written as a percentage?

Convert fraction (ratio) 55/64

Answer: 84.375%

Jiva-tattva has 50 qualities. How much is 50 out of 64 written as a percentage?

Convert fraction (ratio) 50/64

Answer: 78.125%

Lord Krsna is the Supreme Personality of Godhead and cause of all causes.

Krsna is the ORIGINAL Form of God from whom ALL His Visnu and Narayana forms (Visnu-tattva) expand from.

This means the only difference between Srimati Radharani (Visnu-"sakti"-tattva expansion) and Lord Balarama (Visnu-tattva expansion), is Lord Krsna IS the Supreme Personality of Godhead and ORIGINAL cause of all causes, and has 4 more qualities than both Radharani and Balarama and other Visnu-tattva expansions.

Therefore, not even Srimati Radharani, Krsna's eternal consort or Balarama, Krsna's older brother, have all Krsna's 64 qualities in full like Krsna does all the time, they only have 60 of those qualities which is 93.75% of Krsna's 64 qualities.

Lets make this easy to understanding-

Srila Prabhupada - "Tattva is manifested in different ways-

1 - Viṣṇu-tattva, 

2 - Viṣṇu-"śakti"-tattva,

3 - jīva-tattva, like that." (Lecture SB 6.2.7,Vrndavana, Sep 10, 1975)

"Sakti-tattva" means the different categories of "energies" of Krsna, the various categories of living entities (Visnu-tattva, Sakti-tattva Siva-tattva and Jiva-tattva) and non-living sakti (mahat-tattva or matter) as Srila Prabhupada explains.

Srila Prabhupāda - "Sakti means “energy.” There are many types of energies of the Supreme Lord, and all of them are auspicious." (SB Canto 4 Ch 6 text 43 Purport)

Siva-tattva is neither jiva-tattva, Visnu-tattva or Visnu-sakti-tattva. Siva-tattva is in a league of his own having 55 of Krsna's 64 qualities, or having 84.375%

The Visnu-"sakti"-tattva and Visnu-tattva expansions are direct expansions of Krsna, while the jiva-tattva (jiva-souls) are separate expansions of Krsna who have their own personality independent from Krsnas.

Lord Krsna has 64 qualities which is 100% of His own set of qualities.

Visnu-tattva has 60 qualities 93.75%

Visnu-"sakti"-tattva also has 60 qualities 93.75%

Siva-tattva has 55 qualities 84.375%

Jiva-tattva has 50 qualities 78.125%

The Supreme Personality of Godhead and cause of all causes Krsna has all the following 64 transcendental qualities in their fullness.

In actual fact, the extent of His 64 transcendal qualities are inconceivable to even great Vaisnavas.

(46) Very attractive to all women

(48) all-opulent

(49) all-honourable

(50) The supreme controller.

Besides all of the above-mentioned fifty qualities, Lord Krsna possesses five more, which are sometimes partially manifested in Lord Brahma or Lord Siva. 

These transcendental qualities are as follows:

(51) Changeless

(52) all-cognizant

(53) Ever fresh

(54) sac-cid-ananda-vigraha (possessing an eternal blissful body)

(55) Possessing all mystic perfections.

Krsna also possesses five other qualities, which are manifest in the body of Narayana/Visnu, and they are listed as follows:

(56) He has inconceivable potency.

(57) Uncountable universes generate from His body.

(58) He is the original source of all incarnations.

(59) He is the giver of salvation to the enemies whom He kills.

(60) He is the attractor of liberated souls.

Besides these sixty transcendental qualities, Krsna has four more, which are not manifested even in the Visnu/Narayana form of Godhead, what to speak of the demigods or living entities. They are as follows:

(61) He is the performer of wonderful varieties of pastimes (especially His childhood pastimes).

(62) He is surrounded by devotees endowed with wonderful love of Godhead.

(63) He can attract all living entities all over the universes by playing on His flute.

(64) He has a wonderful excellence of beauty which cannot be rivaled anywhere in the creation.

The Absolute Truth is anandamaya (desiring to increase His joy), hence from His original form He expands and becomes many. These emanations from the Supreme Person are of two categories: full expansions and partially manifested expansions.

The Lord's various full and partial expansions and the Lord Himself simultaneously co-exist, only appearing to manifest under the influence of time.

These expansions of the Supreme Being are known as Visnu-tattva, and they are also Supreme Absolute Truth. While non-different from the Lord, the Visnu-tattvas all accept their own role as Godhead in the mood of Servitor to the "original" Supreme Being.

This relationship is the foundation of Vedic monotheism, which encompasses the inconceivable, absolute personal nature of the original Godhead.

The Supreme Being possesses two other expansive qualities known as Siva-tattva and jiva-tattva. Together with Visnu-tattva, these three qualities are representative of the Absolute Person's internal, external and marginal energies.

The Lord has expanded Himself as Lord Siva and Lord Brahma, and we, the living entities, are also expansions. 

Like us, Lord Brahma is also jiva-tattva.

Lord Siva is between Visnu-tattva and jiva-tattva. And Lord Visnu is Visnu-tattva. Visnu-tattva, via media, and jiva-tattva - they are all expansions of the Supreme Personality of Godhead.

Therefore we can summarize as

Lord Krsna has 64 qualities or 100%

Visnu-tattva and Visnu-"sakti"-tattva has 60 qualities or 93.75%

Siva-tattva has 55 qualities or 84.375%

Jiva-tattva has 50 qualities or 78.125%

This is the reason why Krsna is called Param Purushottam, Purnavatar or Supreme Personality of Godhead.

Reference from Srimad Bhagavatam Canto 1 Ch 3 text 29 Purport-

Srila Prabhupāda - "Learned scholars in transcendental subjects have carefully analyzed the summum bonum Krsna to have sixty-four principal attributes. All the expansions or categories of the Lord possess only some percentages of these attributes. 

But Sri Krsna is the possessor of the attributes cent percent. And His personal expansions such as svayam-prakasa, tad-ekatma up to the categories of the avataras who are all visnu-tattva, possess up to ninety-three percent of these transcendental attributes.

Lord Siva, who is neither avatara nor avesa nor in between them, possesses almost eighty-four percent of the attributes. But the jivas, or the individual living beings in different statuses of life, possess up to the limit of seventy-eight percent of the attributes.

In the conditioned state of material existence, the living being possesses these attributes in very minute quantity, varying in terms of the pious life of the living being. The most perfect of living beings is Brahma, the supreme administrator of one universe. He possesses seventy-eight percent of the attributes in full.

All other demigods have the same attributes in less quantity, whereas human beings possess the attributes in very minute quantity. The standard of perfection for a human being is to develop the attributes up to seventy-eight percent in full. The living being can never possess attributes like Siva, Visnu or Lord Krsna. 

A living being can become godly by developing the seventy-eight-percent transcendental attributes in fullness, but he can never become a God like Siva, Visnu or Krsna. He can become a Brahma in due course. 

The godly living beings who are all residents of the planets in the spiritual sky are eternal associates of God in different spiritual planets called Hari-dhama and Mahesa-dhama.

The abode of Lord Krsna above all spiritual planets is called Krsnaloka or Goloka Vrndavana, and the perfected living being, by developing seventy-eight percent of the above attributes in fullness, can enter the planet of Krsnaloka after leaving the present material body."
