Calculator Manual & Training Guide

Everything the tool does, in plain language — what to enter, how each number is worked out, and how to read what comes out. Use it to train, or just read it through start to finish.

SAVE = the monthly mortgage SAFE = years your reserve lasts Two modes: Proposal & Comparison
Section 1

What this tool is

It turns a client's property sale into a clear plan for their next move. From what they're selling, it works out how much money they free up, how much they can borrow, and what they can comfortably buy — then packages it into a clean PDF for the client and an internal brief for you.

The whole idea sits on two words:

  • SAVE — the monthly mortgage instalment. Lower = easier to carry.
  • SAFE — the safety net: how many years of instalments their leftover cash (the reserve) can cover with zero income. Higher = safer.

Every figure is an indicative estimate to guide a conversation — not a bank approval and not financial advice.

Section 2

The two modes

At the top you pick one of two modes. The whole page changes colour so you always know which you're in — gold = Proposal, green = Comparison.

Gold · Proposal

No purchase yet — 4 plans

For prospecting. Enter what they're selling and the tool auto-generates four ready-made plans — from a big safety cushion to maximum wealth-building. Best when the client hasn't picked a property yet and you want to show what's possible.

Green · Comparison

Comparing options — deck

For a client weighing specific choices. Each "option" can hold one OR several properties (e.g. buy A vs buy A + B). The tool lays them side by side and recommends the one with the best 4-year outcome.

Tip: a saved client remembers which mode it was built in and reopens in that mode — the dropdown shows "· Proposal" or "· Comparison" so you know before loading.
Section 3

What you enter

All money figures are monthly, in SGD, unless the label says otherwise.

Buyers

Residency
SC / PR / Foreigner — decides the ABSD rate.
Age
Drives the loan tenure (older = shorter loan = smaller borrowing).
Fixed income /mo
Basic monthly salary. Counted at 100%.
Variable /mo (×70%)
Average monthly commission / bonus / overtime (annual bonus ÷ 12). MAS only recognises 70% of this for the loan — the 30% "haircut". Full-commission earners put everything here.
Debt /mo
Existing monthly commitments (car, other loans). Reduces borrowing.
CPF OA
CPF Ordinary Account they already hold — adds to firepower.
Owns before sale
How many residential properties they own now. Anything you mark as sold below is auto-deducted, so the ABSD/loan count at purchase is correct.
Married couple
A toggle. Tick only if buying together as a married couple — it's needed before ABSD remission can apply. Never assumed.

Property to sell

Sale value
Expected selling price.
Outstanding loan
What's still owed to the bank — repaid from the sale.
CPF used
CPF previously used on this property (incl. accrued interest) — refunded to their CPF OA on sale, so it's still theirs to redeploy.
Owned by
Which buyer owns it — so its count is deducted from the right person at the next purchase.
Agent fee
Your commission %. A red warning appears below 2% (PropNex guideline). GST is added on top automatically.

Settings

Loan interest rate
The rate used for the actual instalment. Required.
TDSR stress rate
The higher "test" rate banks use to check you can still afford it (default 4%).
Default renovation
A renovation budget added to the buy-in.
Property type (Proposal)
Private = TDSR only · EC = lower of TDSR & MSR · HDB = MSR (30%) only, shorter tenure.
Reserve years
How many years of instalments the Conservative / Prudent plans keep aside.

Comparison options

Each option holds one or more properties. Per property you set: price, type (new launch/BUC, private resale, HDB resale), who's buying it, and whether it's own-stay or investment. Investment unlocks rent, maintenance and how many months it's rented; an own-stay new launch lets you set "rent while waiting" for the build.

Section 4

Key terms — explained simply

Firepower — the total cash + CPF the client can deploy. Worked out as:

Sale price agent fee (incl. GST) outstanding loan CPF used = cash proceeds. Then + the CPF refunded back to OA + any CPF they already hold = Firepower.

Eligibility (how much they can borrow) — capped by the rules:

  • TDSR 55% — total monthly loan repayments can't exceed 55% of gross monthly income (minus existing debts), tested at the stress rate.
  • MSR 30% — for HDB/EC only, an extra cap: home loan ≤ 30% of income. The lower of the two wins.
  • Tenure — set by the buyers' income-weighted average age. Older shortens it and lowers the loan.

LTV (loan-to-value) — the max % of price a bank will lend:

1st housing loan
up to 75%
2nd housing loan
about 45%
3rd+ housing loan
about 35%
Important: the loan used is always the lower of the LTV cap and TDSR/MSR eligibility. If the bank won't lend the full LTV, the client makes up the gap in cash — see Section 5.

Buy-in — the upfront money to complete the purchase: Down payment (price − actual loan) + BSD + ABSD + renovation + legal. Whatever firepower is left after the buy-in becomes the SAFE reserve.

SAVE — the monthly mortgage. Year 1 uses the original tenure; from ~12 months you can refinance to a longer tenure, easing it to the lower Year 2+ figure.

SAFE / runway — how long the leftover cash reserve can cover the mortgage with zero income (12 × Year-1 instalment, then 12 × Year-2 each further year).

Stamp duties:

  • BSD — Buyer's Stamp Duty, paid on every purchase (tiered, ~1–6%).
  • ABSD — Additional Buyer's Stamp Duty, charged per buyer based on how many properties they own and their residency. A married couple with ≥1 Singapore Citizen buying their first home jointly can get full ABSD remission ($0) — only when the Married toggle is on.

Investment net rent — rent isn't pure profit. The tool nets it down: rent collected − maintenance − vacancy/agent/repairs − property tax (IRAS estimate) − income tax (estimate)= net rent.

Section 5

How loan & firepower work together

Think of two taps filling a bucket — the loan and the firepower. A plan picks the biggest property where both together are enough, and stops at whichever runs dry first. Here's how that plays out:

A · Small shortfall, plenty of cash
Bank lends a touch less than 75%. Client just pays a little more cash down. Plan proceeds; the SAFE reserve shrinks slightly. No issue.
B · Big shortfall, but large firepower
Bank lends much less than hoped. Firepower covers the whole gap. Still works — more cash goes in, so less is left as reserve.
C · Shortfall AND not enough cash
Neither the loan nor the cash can reach that price. The plan automatically lowers the property price until loan + firepower can truly afford it. The client sees the realistic, affordable home.
D · Why the loan fell short in the first place
Same result, different cause: income too low or too much existing debt (TDSR), an older buyer (shorter tenure), or mostly commission income (only 70% counts). Any of these shrinks the loan, pushing more onto the down payment.
In one line: the loan does what it can, firepower fills the rest, and if together they still fall short, the price drops to what's genuinely affordable.
Section 6

The four proposal plans

In Proposal mode the same firepower is redeployed four ways — same household, the client's call on risk:

Conservative
Keeps the biggest reserve (most SAFE). Smaller purchase, maximum cushion. For the cautious.
Prudent
A confident upgrade that still holds ~2 years of instalments in reserve. The usual lead.
Build Capital
Puts most firepower into the property; little/no reserve — the mortgage becomes their forced savings.
Build Wealth
Most aggressive — a cash top-up on top to buy bigger and build the asset fastest.

Each plan shows its price, the SAVE monthly figure, and the SAFE years — so the client picks the balance they're comfortable with.

Section 7

Reading the on-screen result

After you hit Generate, the summary panel shows:

  • Firepower and (Proposal) Qualifies to borrow, or (Comparison) the Best 4-yr net gain in dollars.
  • The green recommendation banner (Comparison) — says why an option wins: highest projected 4-year gain, how much more than the next option, and how much stays as reserve.
  • Cards for each plan/option, with the recommended one badged and its net gain as the headline number.
The recommended option = the highest projected 4-year net gain (capital growth + net rent − ABSD − rent-while-waiting), while still keeping a sensible reserve.
Section 8

The PDFs & the agent brief

Two downloads, two audiences:

  • Client PDF (green button) — premium, branded with your photo/name. Proposal = a firepower breakdown page + the four plans. Comparison = firepower → allocation → side-by-side table → a dedicated page per option → a written "why this one" case.
  • Agent Brief (dark button, internal) — never give this to a client. It has talking points, objection-handling, and a full worked example showing every number's derivation (firepower, buy-in, 4-year return, SAVE, reserve). The proposal brief works through all four plans.
Watermark: every PDF carries your name faintly across it, and so does this manual — so anything that leaks is traceable to the agent who generated it.
Section 9

Saving clients

  • Save client stores the whole form to your account (it follows you across devices). Saving the same name again overwrites it.
  • The dropdown loads any saved client back — the label shows whether it was a Proposal or Comparison.
  • Reset clears everything for a fresh start.
  • Profiles are private to you — agents never see each other's saved clients.
Section 10

Rules & good practice

Every figure is indicative. Always verify against the bank's actual approval and current IRAS / MAS rules before presenting. This is a planning aid, not financial advice and not a loan approval.
  • Verify before you present — especially the loan amount, ABSD, and any tax estimate.
  • The agent brief is internal only — never hand it to a client.
  • Don't promise outcomes — frame plans as illustrations of what's possible.
  • Comply with CEA & PropNex guidelines, including the 2% commission guideline.
