Asset Registry and Net Worth Documentation

How to read this document

Sections move from purpose → concepts → calculation process → worked examples → edge cases. Formula boxes use plain mathematical notation for clarity; they are conceptual summaries, not API contracts.

• Point lists call out operator-visible behaviour.
• Callouts mark warnings, limitations, or important qualifications.
• Worked examples use round numbers so you can reproduce the arithmetic by hand.

Purpose and scope

The Asset Registry records what a household owns, owes and is insured for, shows what each item is worth today, and projects it forward from the terms entered. It tracks and forecasts; it does not recommend what to buy, sell or repay.

• Record assets, debts and insurance policies with their real terms
• See today's value of each item and why it is that value
• Follow net worth over time and project it forward
• Keep every assumption visible and editable

The Asset Registry surface

Asset Registry (/assets) is web-only and opens for household administrators after a separate unlock (the account password, or an emailed code when two-factor sign-in is on). It locks again on its own after a short while, or with Lock now.

• Four registers: Assets, Debts, Insurance (protection policies) and Goals.
• Adding or editing happens on its own page. The form asks only for what that kind of item needs, and a preview beside it shows today's value, a projection and the figures that follow from the terms, before anything is saved.
• Each asset and debt has a page with its value or balance, a projection with a table view, its recorded history, its terms and what it is linked to.
• The overview leads with net worth, assets and debts side by side, then the forecast, where the value sits, net worth over time, and what is coming up (maturities, premium dates, rate changes, payoffs).
• Asset Registry data is excluded from InteliHouse and every AI feature. There is no consent toggle for it: it is never read.

Balance-sheet identity

Every figure on the overview, the forecast's first year and each item's page start from the same value today, so they agree. The result is only as current as the records behind it; it is not liquid cash, taxable wealth or an independent valuation.

• Assets add, debts subtract.
• Goals count only when marked to be included in net worth; avoid counting money that is also recorded as an asset.
• Sold or closed assets and paid-off debts leave every total and keep their history.
• A transfer between two recorded assets does not create wealth.

Kinds of asset

Each kind asks for the terms that decide its value. They are grouped into classes for the allocation view.

• Cash & deposits: cash and bank balances (optionally earning interest), fixed deposits, recurring deposits, money owed to you (loans given, security deposits, advances, refunds due).
• Investments: stocks & ETFs, mutual funds, SIPs (recurring investments), bonds & sukuk (including treasury bills), crypto, gold & precious metals, business & private equity stakes.
• Retirement & insurance: provident and pension accounts (EPF, PPF, VPF, NPS, 401(k), IRA, DEWS, pension plans), end-of-service gratuity, and insurance plans with a cash or surrender value (ULIP, endowment, whole life, savings plans).
• Property: homes, rental property, land, commercial and off-plan property, with optional rental income.
• Vehicles & valuables: vehicles, electronics, furniture, jewellery, art, watches, collectibles.
• Units and price: for holdings priced per unit (shares, fund units, coins, grams of gold), units × price fills in the value.

Today's value

Today's value starts from the latest dated observation: the purchase, or the latest value you recorded. It is carried forward to today only by a rule you stated: an interest rate, an appreciation or depreciation rate, a straight-line schedule, a known maturity amount, or a statutory formula (gratuity). A trend read from your recorded values is used for projections only; it never changes today's value.

• Recording a value makes it today's value from its date; a value recorded with an older date only adds to the history.
• Removing the latest recorded value makes the one before it current again.
• Each item's page says how its value was arrived at: as recorded, accrued at a rate, on its schedule, worked out from installments, at amortised cost, or by formula.
• A value recorded more than a year ago is flagged on the overview.

Two kinds of rate

Deposit rates (fixed and recurring deposits, provident funds, interest on balances) are nominal yearly rates with a stated compounding frequency, the way banks quote them. Market rates (expected return, appreciation) are effective yearly averages: r a year multiplies the value by (1 + r) each year.

Fixed and recurring deposits

A fixed deposit accrues interest from its deposit date at the stated rate and compounding. If interest is paid out to an account, the deposit stays at its principal and the payout per period is shown. At maturity it either rolls over at the same rate or is paid out and stays at its maturity value; a maturity amount from the receipt, when entered, is the value on that date.

In a recurring deposit, each installment earns interest for exactly the time it is held, compounding at the stated frequency — the method banks use for recurring deposits. Installments stop at maturity.

Recurring investments, provident funds and premium plans

A SIP, a provident or pension account and an insurance plan with premiums all take installments. The first falls on the start date, then one each period; a yearly step-up raises the installment on each anniversary of the start. Installments stop on the end date, or at maturity, and the balance carries on growing.

• A balance from a recent statement is the most accurate starting point. Without one, the value is worked out from the opening amount and every installment since the start, at the stated rate (or what was put in, if no rate is given).
• With Add installments automatically on, today's value moves on from the latest statement by each installment due since, plus growth at the stated rate. Turn it off when each installment is recorded separately, for example as a transfer from a bank account, so none is counted twice.
• Provident funds earn declared interest compounded yearly and can include an employer contribution; market-linked plans grow at the expected return.
• A plan's gain is shown against what has been put in, not against a purchase price.
• Installments imply nothing about returns, so no trend is read from a plan's balance.

End-of-service gratuity

Gratuity is worked out from basic pay and length of service, as if the job ended on the date valued; an expected yearly pay rise and leaving date can be added. The rules are applied as written; an employer's own scheme or contract may differ.

Bonds and sukuk

A bond is valued at amortised cost, the effective-interest method: the yield to maturity that makes the remaining coupons and redemption worth the price paid, applied as time passes. A bond bought below face value rises to it by maturity; one bought above falls to it. A recorded market value restarts the calculation from that price.

• Coupons paid out are income and not part of the value; reinvested coupons are added at the same yield.
• Shown: yield to maturity, coupon income, current yield and the next coupon date.
• Treasury bills have no coupons and grow to face value at their yield.

Vehicles and items that lose value

• Declining balance: the value falls by the stated share each year — value × (1 − d)^t.
• Straight line: the same amount each year, (cost − resale value) ÷ useful life, down to the resale value.
• A recorded value (a revaluation) restarts the schedule: what is left above the resale value is spread over the useful life remaining on that date.
• Neither falls below the resale value entered.

Trends from recorded values

When an asset you value yourself has no stated rate, its forecast follows the trend of its recorded values once they span at least a year: a straight-line fit to the logarithm of the values, which gives the yearly growth the whole history implies. A shorter history is not annualised: a 20% rise in two months reads as about 200% a year and would compound for decades.

• A trend shapes projections only; today's value stays as recorded.
• Until the values span a year, an asset with no stated rate is projected flat at today's value. Its page says so, with the date from which a recorded value starts the trend.
• A depreciating asset whose values rose is given no decline, rather than the rise read as a fall.
• A known maturity amount on an asset bought on a known date implies a contract rate for any term.

Shared ownership and secured debts

• An asset owned jointly can carry the household's share; totals count the share, and the asset's own page shows the whole value.
• A mortgage or car loan can be linked to the property or vehicle it is secured on. The asset then shows equity (its value, in its currency, less the linked balances) and loan-to-value (balances ÷ value).
• Insurance policies can be linked to the vehicle or property they cover.

Debts

A debt's balance is what is owed, on the date the statement shows. Kinds: mortgage, car, personal, education and other loans, credit cards, overdrafts and credit lines, buy-now-pay-later plans, money borrowed from family or friends.

• Fixed installments: each payment covers the month's interest (balance × rate ÷ 12) and some of the balance. With a term and a start date, the installment is worked out over the months left on the term, not the whole original term again.
• Interest only: payments cover the interest and the balance is repaid on the final date. Repaid at the end: nothing is paid until the due date and interest is added to the balance.
• Revolving credit: each month's payment is the larger of the minimum percentage of the balance, the minimum floor and any set amount paid; the share of the credit limit used is shown.
• Fixed, then variable: on the date the fixed period ends the rate changes to the rate entered, and the installment is re-priced over the months then left.
• Follow the schedule: the balance comes down by each installment from its statement date without recording them, and recorded payments count as extra (all principal). Otherwise the balance changes only when payments are recorded.
• A recorded payment pays interest first: from the statement when entered, otherwise worked out at the rate for the days since the previous payment, at most one month. The rest reduces the balance. Removing a payment puts its principal back.
• A debt paid down to nothing is marked paid off and leaves the totals.

On a debt's page, an extra amount each month can be entered as a scenario: the projection shows the payoff date and interest with it, beside the schedule. Nothing changes until a payment is recorded.

Insurance policies

Protection cover — term life, health, critical illness, disability, personal accident, motor, home and travel — is recorded with its cover, premium and dates. Cover pays out only if something happens, so it is never counted in net worth. Plans that build a cash or surrender value are recorded as assets instead.

• Premiums are shown a year, and the next premium or renewal date rolls forward from the date entered by the premium frequency.
• Policies due in the next 60 days appear under Coming up.
• Policy numbers and the names of the people covered or named as beneficiaries are stored encrypted.

Currency

• Each item keeps its own currency; totals and the forecast convert at today's rate, so converted totals move with exchange rates even when balances do not.
• An item that cannot be converted, because no rate is available, is left out of the totals and named, rather than added at face value.
• Projections hold today's exchange rate for every year.

The forecast

The forecast projects every asset by its own model, every debt by its own schedule, and included goals by their interest and recurring deposits, then adds them up year by year in the household currency.

• Views: net worth; assets and debts; assets by class; and put in versus growth, which separates today's value, installments still to come and modelled growth.
• Year one of the forecast is today's net worth.
• Debt payments are assumed to come from future income, not from listed assets.
• Not adjusted for inflation, tax, fees or volatility unless they are part of the rates entered.
• A table view lists every year.

History

• Each asset keeps its recorded values, shown on a time axis so uneven gaps read as gaps.
• Recording a later value keeps the one before it in the history, so the trend has both.
• A net-worth point is saved for each month the registry is opened; the overview shows the change since the previous one.
• Closing an asset records the date and the amount it was sold or paid out for.

Edge cases

• A bank account linked to a cash asset sets that asset's value from the account balance; values recorded on the asset are replaced at the next balance change.
• A transfer from a bank account into an asset adds the amount, converted into the asset's currency, to what the asset is worth on the transfer date.
• Deleting an asset clears the links from bank accounts, debts and policies to it.
• Credit limits are not debts; undrawn credit is not cash.
• Illiquid assets may not sell at the value recorded.
