Use this comprehensive Warframe Riven Calculator to precisely determine the final effectiveness of any Riven Mod on its corresponding weapon, factoring in the base weapon stats, the mod’s generated stats, and the crucial Riven Disposition.

Warframe Riven Formula:
The core formula to determine a stat’s final value when a Riven Mod is applied is shown below. This calculator can rearrange and solve for any missing variable.
Where: FSV = Final Stat Value, BSV = Base Stat Value, RM = Riven Multiplier (%), D = Disposition
Formula Source: Warframe Official Forums – Mechanics Guide, Warframe Wiki – Riven Mod
Variables Explained:
- Base Weapon Stat Value (BSV): The initial value of the stat on the weapon before mods are applied (e.g., Critical Chance, Multishot, Damage).
- Riven Mod Multiplier (RM): The percentage value listed on the Riven Mod itself (e.g., +120% Damage, -60% Zoom). Input this as a raw number (120 or -60).
- Weapon Riven Disposition (D): A hidden multiplier for the Riven’s strength, ranging typically from 0.5 (Weak) to 1.55 (Strong). This value is weapon-specific.
- Final Calculated Stat Value (FSV): The resulting stat value after the Riven Mod has been applied, which is the value you are solving for in most cases.
What is a Warframe Riven Calculator?
A Riven Calculator is an essential tool for high-level Warframe players. It helps estimate or verify the final statistics of a weapon after installing a Riven Mod. Rivens are unique, randomized mods that grant substantial bonuses (and sometimes penalties) to a specific weapon. Their unique nature, combined with the ‘Disposition’ mechanic, makes manual calculation tedious and error-prone.
The key to a Riven’s power is its Disposition, which scales the Riven’s written multiplier up or down. A high-disposition weapon will gain much larger bonuses from the same Riven roll than a low-disposition one. This calculator automates the multiplication process, ensuring Tenno can efficiently compare different Riven rolls and optimize their builds without needing complex spreadsheets or in-game testing.
How to Calculate Warframe Riven Stats (Example):
Let’s find the Final Critical Chance (FSV) for a weapon with 25% Base Critical Chance (BSV), a Riven with +130% Critical Chance (RM), and a Neutral Disposition of 1.0 (D).
- Identify Variables: BSV = 25, RM = 130, D = 1.0.
- Apply Riven Mod Multiplier: First, calculate the Riven’s effective multiplier: (RM / 100) * D = (130 / 100) * 1.0 = 1.30.
- Determine Total Stat Increase: The base stat is multiplied by (1 + Effective Multiplier): (1 + 1.30) = 2.30.
- Calculate Final Value: Multiply the Base Stat by the Total Multiplier: $25 \times 2.30 = 57.5$.
- Result: The Final Critical Chance (FSV) is 57.5%.

Frequently Asked Questions (FAQ):
Disposition acts as a final global multiplier on the Riven’s percentage values. A disposition of 0.5 halves the Riven’s effectiveness, while a 1.55 disposition increases it by 55%, making it critical for the Final Stat Value.
This is often due to rounding. Warframe sometimes truncates or rounds final stat values, and there may be other additive mods (like base elemental damage) that are not accounted for in this Riven-specific formula. Always treat this as a highly accurate estimate.
Yes. If you input a negative value for the Riven Mod Multiplier (RM), the calculator will correctly subtract the stat’s value, showing the reduction in the Final Stat Value (FSV).
While dispositions constantly fluctuate based on usage, they generally range from a low of 0.5 (often for powerful, high-use weapons) up to a maximum of 1.55 (typically for lower-use or less popular weapons).
