How the numbers work

What your plan doesn't model, and why

A projection is a model, and every model has edges. This page names them.

Short answer

Your plan doesn't yet model a second property, refinancing, or service and conservancy charges, and it prices a policy off the owner's age. It also makes a few deliberate choices, such as paying tax a year after the income.

Knowing these helps you and your advisor tell what a number includes, and where a manual adjustment covers the gap.

Here is what your plan doesn’t attempt yet, and where it handles a situation its own way, so you and your advisor never guess what a number includes.

What your plan doesn’t model yet

These situations are real for plenty of households. Your plan just doesn’t have a place for them yet.

  • A second property, or refinancing an existing one. Housing models one property per household. Selling, buying again or refinancing partway through the plan isn’t represented. A rate change means editing Housing directly, not a “refinance” action.
  • Service and conservancy charges, and utilities. Housing projects a property’s purchase, loan and stamp duty in detail, but S&C charges and utilities aren’t their own line. Fold them into your general expenses.
  • True age-based pricing when the insured differs from the owner. Name someone other than the owner as insured, and unless you pick “Others” with their date of birth, premiums and coverage still price off the owner’s age (see below).
  • Some CPF rules. The extra interest from 55, the $5,000 withdrawal limit, low-wage contribution bands, voluntary top-ups and the MediSave cap before 55. See CPF.
  • Google or Apple sign-in. Signing in is by email and password only.
  • Sharing templates between advisors. An advisor’s plan templates are private to them. Sharing or exporting a template to another advisor isn’t available.

How your plan treats some situations

None of these are bugs. They’re deliberate choices your plan makes, worth knowing before a number reads as more precise than it is.

Insurance

Your plan prices a policy’s premium and coverage at the owner’s age, unless you set the insured to “Others” with their own date of birth. Naming your partner as insured doesn’t change that.

Housing

Your plan gives a BTO a 4-year wait from application to keys. An executive condo or new-launch condo waits 3 years from signing to keys by default. You can change either under “Customise the assumptions” in Housing.

Your plan treats “years till completion” as full years before payments start. Entering 3 means payments begin in year 4, not 3.

Your plan models a new-launch condo’s progressive payment stages on the developer’s real billing milestones, such as foundation, structure, roofing and TOP. See the Assumptions reference for the schedule.

CPF

At 55, your plan forms your Retirement Account from your SA first, then your OA, up to your Basic, Full or Enhanced Retirement Sum, rounded down to a whole tier, using your balances at the end of age 54. CPF itself sets aside up to the Full Retirement Sum, so the two can differ. The SA then closes, and your OA stays open with whatever is left. Nothing is paid out as cash. From 55, a cash shortfall draws on your OA first, before investment-linked policies and investments. See CPF for the details.

Income and expenses

In a promotion or job-switch year, your plan’s lifestyle increment replaces the normal yearly expense increase rather than adding to it. Both sit on top of inflation.

Your plan’s projected income tax arrives a year after the income it taxes, plus a prorated first year. This mirrors how Singapore assesses tax after the income is earned. It’s also why your first-year tax rarely matches what you paid: your plan prorates it and works out each year’s tax from the previous year’s income.

Goals and milestones

Your plan treats a recurring goal’s amount as per occurrence, not per year. A monthly goal counts 12 times a year, a twice-yearly goal twice, and so on, before it’s added to your projected expenses.

Children

Your plan sets an unborn (planned) child to female on the polytechnic path by default, since a planned child has no gender or path fields. Once the child is born, add them as a current child with real details in “Family and children”.
