The first plan is written on a Sunday in May, in a notes app, and it is a good one. Essential monthly outgoings for the household come to ₹85,000, rent included. Eight months of that is ₹6,80,000, and ₹6,80,000 is what sits in the sweep-in deposit linked to the salary account. The line reads: emergency fund — done. The second plan is written the following April, in a spreadsheet, by the same two people, and it is also a good one. The flat needs ₹6,80,000 of the household’s own money on top of the loan, in about fourteen months, and the sweep account has ₹6,80,000 in it. That line reads: down payment — arranged. Neither document mentions the other. Neither is wrong. There is one balance and there are two plans, and the only place the error exists is in the space between two files that have never been open at the same time.
Two families hold a receipt for the same wedding hall on the same date. Both receipts are genuine, both amounts were paid, and the manager who took the second booking was not being dishonest — he was looking at a different page. Nothing is discovered until the fourteenth, when the problem is no longer a booking problem.
A double-counted balance is exactly this. Each plan is correct on its own page, the money is really there, and nobody is lying. The clash is invisible until the day both claims arrive, which is also the day nothing can be done about it.
What the arithmetic actually is
Put the two claims in one column and the balance in another, which is a thing neither document does. The claims total ₹13,60,000. The balance is ₹6,80,000. The household is therefore 50 per cent funded against its own written commitments — and there is no page anywhere, in either app, on which the figure 50 appears. That is the whole difficulty with [[double counting]]. It never shows up as a shortfall, because in each plan taken separately there is no shortfall.
| What each document says | The number in it | What it implies about the sweep balance |
|---|---|---|
| The May note | ₹85,000 a month × 8 = ₹6,80,000 | That the ₹6,80,000 stays where it is, untouched, and is available on any Tuesday |
| The April sheet | Own contribution of ₹6,80,000, due in about 14 months | That the ₹6,80,000 leaves the account on a known date and does not come back |
| Both together, which nobody wrote | Claims ₹13,60,000 against a balance of ₹6,80,000 | That one of the two plans is entirely unfunded, and neither document says which |
The day it resolves itself, which is worse than the day it is discovered
Nothing about this is dangerous while both plans are only plans. It becomes concrete on the Tuesday the money goes to the builder, and what happens that Tuesday is not one bad thing but two, moving in opposite directions.
The version that catches people who have no home loan
The commonest double count in Indian households is not cash at all. It is a [[sum assured]]. Take a different family, further along: term cover of ₹1,00,00,000 was bought in one year with a single purpose written next to it — replace the income. A home loan was taken four years later, and from that day the household’s understanding, if anybody says it aloud, is that the policy clears the loan and replaces the income. Those are two claims on one figure, and the event that triggers the first is by construction the same event that triggers the second.
Why double counting survives so well
- Each plan is correct. Scepticism aimed at finding a mistake finds nothing, because there is no mistake inside either document. The defect lives between them.
- [[Mental accounting]] does the concealing. The same balance carries a different label in each plan, and a labelled pot feels like a separate pot. It is the same instinct that makes a ring-fenced retirement account useful, running in the unhelpful direction.
- The claims are usually correlated, which is the part that turns an inconvenience into a crisis. One income funds both plans, so the event that empties the reserve — a job ending, a business quarter going wrong — is also the event that makes the second commitment unaffordable. With insurance the correlation is total: the claim that pays is the claim that ends the income.
- The two documents have different owners in the household. Very often one person keeps the emergency plan and the other keeps the purchase plan, and each is confident the other has accounted for it.
- Nothing forces a reconciliation. No statement, app or adviser produces a page listing every commitment against every balance. If the household does not build it, it does not exist.
- Emergency fund: ₹6,80,000 held, ₹6,80,000 required. Funded.
- Down payment: ₹6,80,000 held, ₹6,80,000 required. Funded.
- Every number in both documents is accurate.
- The household describes itself, honestly, as well prepared.
- No review of either plan can detect anything.
- Claims: ₹13,60,000. Balances: ₹6,80,000. Coverage: 50 per cent.
- One of the two plans is entirely unfunded and neither says which.
- The purchase raises essential outgoings by ₹32,000 a month.
- Eight months of cover after the purchase costs ₹9,36,000, not ₹6,80,000.
- The choice is now explicit: delay, reduce, or accept a period with no reserve.
- 1One page, two columns, no exceptions
On the left, every balance you hold, each appearing exactly once — bank, sweep deposit, liquid fund, equity, PPF, EPF, gold, everything. On the right, every commitment with a rupee amount and a date. This page is boring, takes about forty minutes, and is the only artefact that can detect the error at all.
- 2Draw one line from each claim to the balance that will fund it
The moment two lines arrive at the same balance, you have found a double count. It does not matter how sensible each plan was; the question is only whether any balance is on the receiving end of more than one line.
- 3Ask what the commitment does to the requirement, not only to the balance
For each claim, write the change in monthly outgoings it causes. A purchase that adds a fixed EMI raises the reserve you need at the same moment it consumes the reserve you have. This single line is what the flat’s costing left out.
- 4Check whether the two claims can arrive together
Independent claims on one balance are a scheduling problem. Correlated claims on one balance are a solvency problem. One income funding both, or an insured event that ends the income and calls the loan, means the claims are correlated by construction and should be treated as simultaneous.
- 5Resolve it on paper, while all the options still exist
A double count found today can be settled by delaying the purchase, reducing it, funding the reserve separately or consciously accepting a defined gap for a defined period. Found on the day both claims arrive, only the last of those is still available, and it is not being chosen — it is being suffered.
The page has just been drawn, and it shows two lines into one balance
You have ₹6,80,000 in the sweep account. The emergency plan claims it as eight months of cover at ₹85,000 a month. The flat plan claims it as the own-contribution, due in fourteen months. Both plans were written by you.
A household holds ₹6,80,000. Its emergency plan requires ₹6,80,000 and its down-payment plan requires ₹6,80,000. What is the most accurate description of its position?
May mein notes app mein likha: ghar ka zaroori kharch ₹85,000 mahina, 8 mahine ka reserve ₹6,80,000, aur sweep account mein utna hi pada hai — "emergency fund ho gaya". Agle April sheet mein likha: flat ke liye apna hissa ₹6,80,000, chaudah mahine baad — "down payment ka intezaam ho gaya". Dono kaagaz sahi hain, dono "ho gaya" bol rahe hain, aur dono ek hi paise ki baat kar rahe hain. Daawa ₹13,60,000, paisa ₹6,80,000 — yaani aadha, aur yeh 50 ka aankda kisi bhi page pe likha nahi hai. Phir jis mangal ko paisa builder ko gaya, do cheezein ek saath huin: account zero, aur EMI ₹58,000 shuru jabki kiraya ₹26,000 band — kharcha ₹85,000 se ₹1,17,000. Ab 8 mahine ke reserve ki keemat ₹9,36,000 hai aur haath mein kuch nahi. Jo cheez reserve khaati hai, wahi aksar reserve ki zaroorat bhi badha deti hai. Yahi baat term plan pe bhi lagti hai: ₹1 crore ka cover jo ₹62 lakh ka loan bhi chukayega aur ghar bhi chalayega, asal mein ₹38 lakh hai — ₹72,000 mahine ke hisaab se saade gyarah saal nahi, saade chaar saal. Ilaaj ek page hai: har balance ek baar likho, har zimmedari rakam aur tareekh ke saath — jis balance pe do teer aa rahe hon, wahi gadbad hai.
- A double-counted balance produces no shortfall inside either plan, so no review of either plan can find it.
- The only artefact that detects it is one page listing every balance once and every commitment with an amount and a date.
- A commitment that consumes a reserve usually raises the reserve required, because it converts a flexible outgoing into a fixed one.
- Correlated claims are the dangerous case: one income funding both, or an insured event that simultaneously ends the income and calls the loan.
- A sum assured that must clear a loan and replace an income is doing two jobs — read the cover in months of living, after the loan.
