How much to save, how much to spend?

The 20% rule doesn't apply for everyone. Let's start from what you actually save and spend.

Your money in

Essentials are what you must spend to live. Salary starts at the median of Singapore's workforce, because averages get dragged up by high earners.

Gross monthly salaryS$

The top number on your payslip, before CPF and tax come out. Not what lands in your bank account.

Monthly essentials, or break it down by category right below itS$

Rent, food, transport, bills, insurance. Everything left over is discretionary.

Emergency cash already savedS$

7 in 10 Singaporeans keep 3-6 months of expenses saved (MoneySense 2023).

About you

Age and legal status drive your CPF and tax. This moves the number more than anything else here.

Your age
Residency
Tax status

Tax resident if you were in Singapore 183 days last year. Most work-pass holders are.

Your safety net

How much cover, and how fast to build it.

Emergency cover
Build it in months
Your monthly plan
S$1,100/mo to save

When the fund is full

Keep the habit going. Your retirement calculator sizes the investing amount.

How this is worked out

The whole plan is six lines of arithmetic. The sophistication is in what feeds them: your take-home pay is computed from your exact age, residency, and tax status against the real CPF and IRAS tables. No rough percentages, no guessing.

take-home     = gross − your CPF − monthly income tax
discretionary = take-home − essentials
fund target   = essentials × cover − cash already saved
monthly save  = min(target ÷ timeline, 80% × discretionary)
guilt-free    = discretionary − monthly save
savings rate  = monthly save ÷ take-home

Common questions

Why not just save 20%?

A flat percentage ignores that essentials don't scale with income. A S$3,000 earner with S$1,800 of essentials has about S$587 of discretionary income, but 20% of gross asks for S$600, more than exists. Start from your real essentials instead.

Does CPF count as savings?

For Singapore citizens and permanent residents aged 55 and below earning above S$750 a month, 20% comes from you and 17% from your employer. It is illiquid but yours and growing. This page plans cash savings on top, and keeps the two numbers separate on purpose.

How big should my emergency fund be?

Three to six months of essential spending, in cash you can touch tomorrow. Not investments, and not CPF.

What happens when my emergency fund is full?

The habit continues, but the amount gets re-sized. Your emergency build rate was never an investing rate, so size the investing amount with the retirement calculator.

Does this handle my income tax?

Yes. It runs the same YA2024-onwards tax bands and exact-age CPF and earned income relief as the income tax calculator, then works from your take-home pay.
