Introductory Context
"This topic provides a complete capital requirement reference for every premium selling strategy covered in this module and the preceding modules -- from the simple cash-secured put through the advanced weekly theta harvesting system. For each strategy, the minimum viable capital is calculated from three inputs: the lot size, the maximum loss per lot (from the strategy's stop-loss rule), and the 2 percent position sizing constraint. "
Capital Requirement Calculation Methodology
For any strategy: minimum viable capital = maximum loss per lot / 0.02 (the 2 percent rule). The maximum loss per lot is: for credit spreads = (wing width - net credit) x lot size. For naked options with stop = (stop-loss premium - original premium) x lot size. For cash-secured puts = strike price x lot size. For iron condors = (wing width - net credit) x lot size (per side).
Example calculations: Nifty monthly bull put spread (300-point wings, Rs 22 credit): maximum loss = (300 - 22) x 75 = Rs 20,850. Minimum capital = Rs 20,850 / 0.02 = Rs 10,42,500 (approximately Rs 10.5 lakh). Nifty weekly bull put spread (200-point wings, stop at 1.5x on Rs 18 credit): maximum stop-loss loss = 0.5 x Rs 18 x 75 = Rs 675. Minimum capital = Rs 675 / 0.02 = Rs 33,750 (approximately Rs 35,000). Wait -- this seems very low. Let me reconsider: the stop-loss loss is the NET additional loss after accounting for the credit already received. This is Rs 675. But the total capital at risk includes the margin required to hold the spread, which is significantly higher than Rs 675. For position sizing purposes, use the maximum loss (the stop-triggered loss amount) not the margin, as the 2 percent refers to the maximum loss the trade can produce.
Minimum Viable Capital Reference by Strategy
Cash-secured put (HDFC Bank 1,650 strike, lot 550): Full obligation = Rs 1,650 x 550 = Rs 9,07,500. Minimum capital = Rs 45 lakh+ (Rs 9 lakh is the cash deployed, but 2% rule on maximum loss: maximum loss at stop = Rs 19 credit x 2 = Rs 38 loss x 550 = Rs 20,900. Minimum = Rs 20,900 / 0.02 = Rs 10.45 lakh). Nifty monthly credit spread (300-pt): Rs 10.5 lakh. Nifty iron condor (300-pt wings each side): Rs 10.5 lakh. Nifty weekly credit spread (200-pt stop-loss based): Rs 33,750. Nifty short straddle with stop: Rs 3,600 / 0.02 = Rs 1.8 lakh. Minimum viable: Rs 5-10 lakh for most systematic programmes.
Capital Allocation Across Multiple Strategies
For traders running multiple simultaneous strategies (monthly programme + weekly supplement), the capital allocation must account for the combined exposure. Total capital at risk = sum of maximum losses from all simultaneously held positions. This combined risk should not exceed 4 to 5 percent of the account (applying the 2 percent rule to each individual position but recognising that multiple simultaneous positions increase the total programme risk).
Example: Rs 12 lakh account. Monthly credit spread: 1 lot Rs 20,850 maximum loss = 1.74 percent of account. Weekly credit spread (simultaneous): 1 lot Rs 675 maximum stop loss = 0.06 percent of account. Combined: 1.80 percent of account. Well within the 4 to 5 percent combined maximum. This account can comfortably run both the monthly and weekly programmes simultaneously. For a Rs 6 lakh account: monthly spread Rs 20,850 = 3.5 percent -- exceeds the 2 percent single-trade limit. Not viable at 1 lot. Must use a narrower spread (Rs 100 to Rs 150 point width) that produces a maximum loss below Rs 12,000 (2 percent of Rs 6 lakh).
The Capital Scaling Effect
As the account grows (from initial capital to programme profits accumulated over months and years), the 2 percent maximum loss threshold increases, allowing larger position sizes and higher absolute income. A programme that starts at Rs 10 lakh (1 lot, Rs 20,000 income target per year) grows: after Year 1 with Rs 20,000 income: Rs 10.2 lakh. 2% = Rs 20,400. Still 1 lot. After Year 2: Rs 10.4 lakh. After Year 5 of consistent income (Rs 20,000-25,000 per year): Rs 12 to Rs 13 lakh. Now 2% = Rs 24,000 to Rs 26,000. Still 1 lot (assuming Rs 20,850 maximum loss). Compounding from options income alone is slow -- the programme should be supplemented by additional capital deposits to reach the 2-lot threshold (Rs 21 lakh). The capital scaling insight: the systematic income programme becomes significantly more impactful at 2 lots (Rs 40,000 to Rs 50,000 annual income) versus 1 lot -- achieved by growing the account to Rs 21 lakh through combination of programme income and additional capital.
The minimum viable capital calculation is the first financial analysis to perform before starting any premium selling programme. Attempting a strategy below its minimum viable capital forces position sizing violations (using more than 2 percent per trade) or produces negligible absolute income that does not justify the programme's complexity. Match the strategy to the account. Start with the strategy tier appropriate for the available capital and grow into higher-tier strategies as the account grows.
Margin Requirements Are Not the Same as Capital Requirements
The broker's SPAN margin requirement for a credit spread (typically Rs 15,000 to Rs 50,000 per lot) is the minimum capital required to HOLD the position. The 2-percent-rule capital requirement (Rs 10.5 lakh for a Rs 20,850 maximum loss spread) is the account size required to make that position's maximum loss acceptable within the programme's risk parameters. The margin requirement is a FLOOR; the 2-percent-rule capital requirement is the APPROPRIATE account size. Trading a Rs 20,850 maximum loss spread on a Rs 3 lakh account is possible from a margin perspective (margin may only be Rs 15,000) but is grossly irresponsible from a risk management perspective (the Rs 20,850 maximum loss is 7 percent of the Rs 3 lakh account -- 3.5x the maximum acceptable risk per trade).
