Riven Calculator Warframe

Warframe Riven Mod Kuva Cost Calculator

Calculate the total Kuva required to cycle your Riven mod a specific number of times based on its current roll count.

function calculateKuvaCost() { var currentRollsInput = document.getElementById("currentRolls"); var additionalRollsInput = document.getElementById("additionalRolls"); var resultDiv = document.getElementById("kuvaResult"); var currentRolls = parseInt(currentRollsInput.value); var additionalRolls = parseInt(additionalRollsInput.value); if (isNaN(currentRolls) || currentRolls < 0) { resultDiv.style.display = "block"; resultDiv.innerHTML = "Please enter a valid current roll count (0 or higher)."; return; } if (isNaN(additionalRolls) || additionalRolls <= 0) { resultDiv.style.display = "block"; resultDiv.innerHTML = "Please enter a valid number of desired additional rolls (1 or higher)."; return; } var totalKuvaNeeded = 0; // Costs to perform the Nth roll. Roll 1 is index 0. // Roll 1=900, 2=1000, 3=1200, 4=1400, 5=1700, 6=2000, 7=2350, 8=2750, 9=3150. // Roll 10 and beyond = 3500. var baseCosts = [900, 1000, 1200, 1400, 1700, 2000, 2350, 2750, 3150]; var cappedCost = 3500; var capThresholdRoll = 10; for (var i = 1; i <= additionalRolls; i++) { var rollNumberBeingPerformed = currentRolls + i; if (rollNumberBeingPerformed < capThresholdRoll) { // Use base costs array (adjusting for 0-based index) totalKuvaNeeded += baseCosts[rollNumberBeingPerformed – 1]; } else { // Use capped cost totalKuvaNeeded += cappedCost; } } var finalRollCount = currentRolls + additionalRolls; resultDiv.style.display = "block"; resultDiv.innerHTML = "

Understanding Warframe Riven Mods and Mechanics

Riven Mods are unique, potent upgrades for weapons in Warframe that offer randomly generated stats. Obtaining a "god roll" Riven for a popular weapon is an endgame pursuit for many Tenno. Understanding how they work, specifically regarding Disposition and the Kuva cycling process, is crucial for efficient resource management.

Riven Disposition Explained

Not all Rivens are created equal. The strength of the stats on a Riven is dictated by the weapon's Riven Disposition. This is a multiplier ranging roughly from 0.5x to 1.55x, represented in-game by 1 to 5 dots.

• Low Disposition (0.5x – 0.7x): Popular, powerful weapons (like the Bramma or Nukor) have low disposition to keep them balanced. Their Riven stats will be lower.
• High Disposition (1.3x – 1.55x): Less popular or weaker weapons have high disposition, making Rivens for them extremely powerful to encourage their use.

When you see a stat on a Riven, its value is the base stat type multiplied by the weapon's disposition and adjusted by the number of positive and negative stats on the mod.

The Kuva Cycle Process

When you first unveil a Riven, its stats are random. To change these stats, you must "cycle" or "roll" the Riven using Kuva, a resource obtained from high-level Grineer missions. Each cycle generates a new set of random stats (and potentially a new polarity), and you are given the choice to keep the old stats or accept the new ones.

The Increasing Cost of Rolling

The Kuva cost to cycle a Riven increases with the number of times it has already been rolled. This mechanic makes chasing a perfect roll increasingly expensive. The calculator above helps you estimate this cost.

• Roll 1 (0 to 1): 900 Kuva
• Roll 5 (4 to 5): 1,700 Kuva
• Roll 10+ (9 to 10 onwards): The cost caps at 3,500 Kuva per roll.

Because the cost caps at 3,500 Kuva past the 9th roll, veterans often spend tens or even hundreds of thousands of Kuva searching for specific stat combinations like Critical Chance, Critical Damage, and Multishot with a harmless negative curse.
