Full math for every number on the flagship screen, worked out for a ₹1 Cr corpus · Balanced preset · 30% slab · 8% FD baseline. Change any of those and the formulas below still apply — just re-substitute your values.

Step 1 · corpus split

How ₹1 Cr splits across four sleeves

The Balanced preset assigns a fixed percentage to each sleeve. Every rupee is deployed — the shares always sum to 100%.

Equity SWP40%₹40,00,000
Total corpus100%₹1,00,00,000
Step 2 · income per sleeve

Each sleeve produces year-1 income

Different sleeves are taxed differently. That's the whole point — post-tax cash flow depends on the mix, not just the headline yields.

Guaranteed sleeve₹1,38,460 /yr

Fixed-coupon bonds (RBI floating-rate savings bonds, PSU bonds). Interest is added to your income and taxed at your full slab rate.

net = principal × yield × (1 − slab)
= ₹25,00,000 × 8.05% × (1 − 31.2%)
= ₹25,00,000 × 0.0805 × 0.688
= ₹2,01,250 × 0.688
= ₹1,38,460 /yr
Appears in: the "Guaranteed" segment of the payout calendar (₹69,230 in Jan + Jul), inside the flagship's y1.guaranteedNet engine output.

Tax-free bonds₹88,500 /yr

Legacy PSU tax-free bonds (NHAI, PFC, REC etc.). Coupons are exempt from income tax under section 10(15). Lower headline yield, but nothing bites into it.

net = principal × yield (no tax)
= ₹15,00,000 × 5.9%
= ₹15,00,000 × 0.059
= ₹88,500 /yr
Appears in: the tax-free bar on the payout calendar (whole coupon in one user-selected month, default March).

InvIT / REIT₹1,58,400 /yr

Quarterly distributions from infrastructure / real-estate trusts. Blend of interest, dividend, and return-of-capital — modelled here as a single effective tax rate (default 12%).

net = principal × yield × (1 − effective tax)
= ₹20,00,000 × 9% × (1 − 12%)
= ₹20,00,000 × 0.09 × 0.88
= ₹1,80,000 × 0.88
= ₹1,58,400 /yr
Appears in: the InvIT/REIT bars on the payout calendar (₹39,600 each in Mar, Jun, Sep, Dec).

Equity SWP₹2,20,000 /yr

Systematic withdrawal from an equity hybrid fund. The engine steps monthly: fund grows at monthly-return rate, you withdraw a fixed amount, cost basis is consumed proportionally. Only the gain inside each withdrawal is taxable.

annual withdrawal = equity × withdrawal rate
= ₹40,00,000 × 5.5%
= ₹2,20,000 /yr
realized gain, year 1 ≈ small (fund has barely appreciated)
Simulated monthly: total realized ≈ ₹25,000 for year 1
LTCG tax = max(0, realized − ₹1,25,000) × 12.5%
= max(0, ₹25,000 − ₹1,25,000) × 12.5%
= max(0, −₹1,00,000) × 12.5%
= ₹0 (exemption fully shields year-1 gain)
net = annual withdrawal − LTCG tax
= ₹2,20,000 − ₹0
= ₹2,20,000 /yr
Appears in: the equity SWP bars on the payout calendar (₹18,333/mo, every month, all 12 months). At larger corpuses year-1 realized gain will exceed the ₹1.25L exemption, LTCG kicks in — this is the "fixed exemption shrinks in impact" property.
Step 3 · aggregate

Sum the sleeves, divide by 12

All year-1 sleeve nets add up to the annual in-hand income. Divide by 12 for the monthly number shown across the flagship.

annual net = guaranteedNet + taxfreeNet + yieldcoNet + equityNet
= ₹1,38,460 + ₹88,500 + ₹1,58,400 + ₹2,20,000
= ₹6,05,360 /yr
monthly in-hand = annual net ÷ 12
= ₹6,05,360 ÷ 12
= ₹50,447 /mo
Appears in 7 places: Pair 2 RIGHT, StickyPair in-hand, VerdictCard in-hand reference, Payout calendar avg line & sweep note, Year-by-year table row 1 (both Monthly and Today's ₹ columns — identical in year 1 because deflator = 1).
Step 4 · pair 1 — tax bite

What ₹1 Cr in a plain 8% FD would produce

Pair 1 compares a naive 8% FD before and after your slab. Both numbers on the same instrument — the chip between them is the true tax.

pre-tax = corpus × 8% ÷ 12
= ₹1,00,00,000 × 0.08 ÷ 12
= ₹8,00,000 ÷ 12
= ₹66,667 /mo
post-tax = corpus × 8% × (1 − slab) ÷ 12
= ₹1,00,00,000 × 0.08 × 0.688 ÷ 12
= ₹5,50,400 ÷ 12
= ₹45,867 /mo
tax bite = pre-tax − post-tax = corpus × 8% × slab ÷ 12
= ₹66,667 − ₹45,867
= ₹20,800 /mo
Appears as: Pair 1 LEFT = ₹66,667, Pair 1 RIGHT = ₹45,867, Pair 1 chip = "tax takes ₹20,800/mo", meter = 69% reaches you / 31% never arrives (mirrors the 31.2% slab).
Step 5 · pair 2 — mix delta

Balanced split vs plain 8% FD, both post-tax

Pair 2's LEFT is the same ₹45,867 from Pair 1's RIGHT — the FD baseline carried forward. RIGHT is the balanced 4-sleeve result. The chip is the honest mix advantage.

mix delta = balanced in-hand − FD in-hand
= ₹50,447 − ₹45,867
= ₹4,580 /mo
Appears as: Pair 2 chip = "smart mix gains ₹4,580/mo" (teal), StickyPair delta = "▲ ₹4,580 /mo vs all-FD".
Step 6 · verdict

Is ₹50,447/mo «kaafi» for your target?

The VerdictCard compares your monthly target against the balanced in-hand. Two words decide it: whether you have enough, or how much more per month you need.

delta = in-hand − target
= ₹50,447 − ₹1,00,000
= −₹49,553 (shortfall)
verdict
  if delta ≥ 0 → “Kaafi hai ✓”
  else → “Abhi kaafi nahi · ₹|delta|/mo aur chahiye”
Since delta = −₹49,553 (< 0):
→ “Abhi kaafi nahi · ₹49,553/mo aur chahiye”
Appears as: VerdictCard headline (rust "Abhi kaafi nahi" or teal "Kaafi hai ✓") + sub with the magnitude and in-hand reference.
Reference

All formulas on one page

Every number the flagship shows, boiled down. Substitute your corpus / slab / preset and rerun the math.

Sleeve nets (year 1)
  guaranteedNet = alloc% × corpus × yg × (1 − slab)
  taxfreeNet   = alloc% × corpus × ytf
  yieldcoNet   = alloc% × corpus × yyc × (1 − reit-tax)
  equityGross  = alloc% × corpus × eqw
  equityNet    = equityGross − max(0, realized − ₹1.25L) × 12.5%
Aggregate
  annualNet  = guaranteedNet + taxfreeNet + yieldcoNet + equityNet
  monthlyNet = annualNet ÷ 12  ← the in-hand
FD baseline (Pair 1 + Pair 2 LEFT)
  preTax  = corpus × fd ÷ 12
  postTax = corpus × fd × (1 − slab) ÷ 12
  taxBite = preTax − postTax = corpus × fd × slab ÷ 12
Comparison chips
  Pair 1 chip = taxBite    ← "tax takes ₹X/mo"
  Pair 2 chip = monthlyNet − postTax  ← "smart mix gains ₹Y/mo"
Verdict
  delta = monthlyNet − target
  delta ≥ 0 → “Kaafi hai ✓”
  delta < 0 → “Abhi kaafi nahi · ₹|delta|/mo aur chahiye”

Every calculation above uses the flagship's default assumptions (guaranteed yield 8.05%, tax-free yield 5.9%, InvIT yield 9% at 12% effective tax, equity return 10.5% with 5.5% initial withdrawal, FD baseline 8%). Changing any input in the calculator re-runs the same formulas with your numbers.
