Every property listing shows two numbers: the price and the expected rent. From those two numbers, agents and portals derive one metric: gross yield. A RM 500,000 condo renting for RM 2,200/month shows a "5.3% yield" in the listing. That number is accurate. It is also useless.
Gross yield ignores the mortgage payment. It ignores maintenance fees, sinking fund, assessment tax, quit rent, insurance, vacancy, agent commission, and income tax. It ignores the fact that you are not paying RM 500,000 in cash — you are putting down RM 50,000 and borrowing RM 450,000 at 4% for 35 years. After all of those costs, the property that shows 5.3% gross yield might generate negative RM 300/month in actual cashflow. Or it might generate positive RM 400/month. You cannot tell from gross yield alone.
The PropCashflow Net Cashflow Calculator gives you the number that agents never show: your actual monthly cashflow after every cost is paid. This guide walks through every input, explains what each metric means, and shows a complete worked example.
The Number Agents Never Show You
Consider two properties, both showing "5% gross yield" in the listing:
Property A: RM 400,000 condo, RM 1,667/month rent
- Maintenance: RM 250/month
- Loan installment (90%, 4%, 35yr): RM 1,594/month
- After vacancy, agent, tax, and expenses: -RM 412/month (negative cashflow)
Property B: RM 400,000 condo, RM 1,667/month rent
- Maintenance: RM 150/month
- Loan installment (90%, 4%, 35yr): RM 1,594/month
- After vacancy, agent, tax, and expenses: -RM 282/month (negative cashflow)
Both show 5% gross yield. Neither produces positive cashflow at 90% financing. The only difference is RM 100/month in maintenance fees — but that translates to RM 1,200/year in cashflow impact.
Now change one variable — loan margin to 70% instead of 90%:
Property A (70% LTV): Loan installment drops to RM 1,239/month → -RM 57/month (nearly break-even) Property B (70% LTV): Loan installment drops to RM 1,239/month → +RM 73/month (positive cashflow)
Same gross yield. Same listing. Completely different investment outcomes depending on financing and expenses. The cashflow calculator reveals these differences instantly.
Step-by-Step Calculator Walkthrough
Step 1: Enter Property Price and Expected Rent
Property Price (RM): The agreed or asking price. This is the base for all calculations — loan amount, stamp duty, down payment, and yield metrics.
Monthly Rent (RM): Based on actual comparable rentals in the same building or area, not the agent's "potential" figure. Check active listings on iProperty, PropertyGuru, or Mudah for the same development. Use the median asking rent, not the highest.
Getting the rent estimate right is critical. A RM 200/month overestimate on a RM 500,000 property swings the gross yield by 0.48 percentage points and the monthly cashflow by RM 200 minus tax effects. Use conservative numbers — if the calculator shows positive cashflow at a conservative rent estimate, the investment is likely sound.
Step 2: Set Financing Terms
Three inputs define your mortgage:
Loan margin (%): How much of the property price you are financing. Common values:
| Scenario | Typical Margin |
|---|---|
| Citizen, first two properties | 90% |
| Citizen, third property onward | 70% |
| PR | 80-90% |
| Foreigner | 60-70% |
| Cash purchase | 0% |
Interest/profit rate (%): The annual rate on your loan. For conventional loans, this is the effective rate (BLR minus spread). For Islamic financing (Musharakah Mutanaqisah, Tawarruq), this is the ceiling profit rate. Current market range for new residential loans: 3.8% – 4.5%.
Tenure (years): Maximum 35 years for most residential properties. Longer tenure reduces the monthly installment but increases total interest paid over the life of the loan. For cashflow analysis, use the actual tenure you plan to take — not the maximum available.
The calculator computes the monthly installment using the standard amortization formula. This is the single largest monthly outflow for a leveraged property and the primary determinant of whether cashflow is positive or negative.
Setting margin to 0% simulates a cash purchase. The mortgage line disappears from the results, and the cash-on-cash return is calculated against the full property price plus acquisition costs.
Step 3: Enter Monthly and Annual Expenses
These are the operating costs of holding the property. Enter each expense separately for an accurate breakdown:
| Expense | Where to Find It | Typical Range |
|---|---|---|
| Maintenance fee | JMB/MC billing, ask developer/agent | RM 150 – RM 700/month |
| Sinking fund | Usually 10% of maintenance | RM 15 – RM 70/month |
| Assessment tax | Local council website, annual bill | RM 500 – RM 2,000/year |
| Quit rent | State land office, annual bill | RM 50 – RM 500/year |
| Fire insurance | Bank/lender requirement | RM 300 – RM 1,200/year |
| Repairs allowance | Budget estimate | RM 50 – RM 150/month |
Maintenance fees are the most variable line item. A basic apartment at RM 0.20/sqft for 800 sqft costs RM 160/month. A premium condo at RM 0.50/sqft for 1,200 sqft costs RM 600/month. This RM 440/month difference is RM 5,280/year — often enough to flip a property from cashflow-positive to cashflow-negative.
Before committing to a property, verify the actual maintenance fee with the JMB or management corporation. Never rely on the developer's brochure figure for completed properties — fees are set by the JMB and may differ from the original projection.
Step 4: Set Vacancy Rate and Agent Commission
Vacancy rate (%): The percentage of the year the property sits empty between tenants. Default is 8.3%, which represents one month of vacancy per year. This is a reasonable baseline for most established areas.
| Market Condition | Suggested Rate |
|---|---|
| Oversupplied area, new development | 16.7% (2 months) |
| Average market, established area | 8.3% (1 month) |
| High-demand area, limited supply | 4% (2 weeks) |
| Long-term tenant, renewed tenancy | 0% |
Vacancy directly reduces your effective rental income. At RM 2,500/month gross rent, the difference between 0% and 16.7% vacancy is RM 5,000/year in lost income. Be honest with this input — most investors underestimate vacancy.
Agent commission: Standard is one month's rent for a two-year tenancy agreement. Amortized monthly, this is approximately 4.2% of gross rent. If you self-manage and find tenants yourself, set this to zero. If your agent charges differently (some charge half-month for renewals), adjust accordingly.
Step 5: Set Tax Parameters
Residency status: Resident (progressive rates, 0%-30%) or Non-Resident (flat 30%). This is the same distinction covered in detail in the Rental Income Tax Calculator guide.
Other chargeable income: For residents, enter your employment/business income. Rental income stacks on top and is taxed at the marginal rate. Higher other income means a higher marginal rate on rental income, which reduces your after-tax cashflow.

Step 6: Read the Results Dashboard
The results panel provides a complete financial picture:
Monthly Breakdown:
| Line Item | Description |
|---|---|
| Gross monthly rent | Your entered rent amount |
| Less vacancy | Rent x vacancy rate |
| Less agent commission | Amortized monthly agent fee |
| Effective rent | Gross rent minus vacancy and agent |
| Less operating expenses | Maintenance, sinking fund, insurance, tax, quit rent, repairs |
| NOI (Net Operating Income) | Effective rent minus all operating expenses |
| Less mortgage payment | Monthly loan installment (P+I) |
| Less income tax | Tax on net rental income at applicable rate |
| Net Monthly Cashflow | The final number — what goes into or comes out of your pocket |
Yield and Return Metrics:
| Metric | Formula | What It Tells You |
|---|---|---|
| Gross Yield | (Annual rent / Property price) x 100 | Headline yield — starting point only |
| Net Yield | (Annual NOI / Property price) x 100 | Return on the asset before financing |
| Cash-on-Cash Return | (Annual net cashflow / Cash invested) x 100 | Return on your actual cash outlay |
| Break-Even Rent | The rent at which net cashflow = RM 0 | Stress-test minimum viable rent |
NOI vs. Net Cashflow: Why Both Matter
Net Operating Income (NOI) is the property's income after all operating expenses but before financing costs and income tax. It measures the property's performance independent of how you finance it.
Net Cashflow is what you actually take home after everything — including the mortgage payment and income tax. It measures the investment's performance given your specific financing structure.
Why does the distinction matter? Because the same property can have a positive NOI but negative cashflow (common with high leverage), or a negative NOI but you are still holding because you expect capital appreciation. The calculator shows both so you can separate the property's fundamental performance from your financing decision.
Example:
- NOI: RM 800/month (property is fundamentally sound)
- Mortgage: RM 1,200/month (high financing cost)
- Net cashflow: -RM 400/month
The property is operationally profitable (RM 800 NOI). But the leverage turns it cashflow-negative. Reducing the loan margin, negotiating a lower rate, or extending the tenure would improve cashflow without changing the NOI. Alternatively, a cash buyer would capture the full RM 800 NOI as cashflow.
Understanding the Yield Metrics
Gross Yield
Gross Yield = (Annual Rent / Property Price) x 100
This is what appears in listings. It is a useful screening metric — properties below 4% gross yield rarely produce positive cashflow with 90% financing. But it tells you nothing about the actual return after costs.
Net Yield
Net Yield = (Annual NOI / Property Price) x 100
Accounts for vacancy, agent, and all operating expenses. A more meaningful comparison metric because it strips out the costs of running the property. Two properties with 5% gross yield might have 3.2% and 4.1% net yield — the latter has lower operating costs and is fundamentally more profitable.
Cash-on-Cash Return
Cash-on-Cash Return = (Annual Net Cashflow / Total Cash Invested) x 100
This is the metric that matters most for leveraged investors. Total cash invested is your down payment plus all acquisition costs (stamp duty, legal fees). It measures the return on the actual cash you put in, accounting for the effect of leverage.
Example:
- Property: RM 500,000
- Cash invested: RM 75,000 (down payment + stamp duty + legal fees)
- Annual net cashflow: RM 4,800 (RM 400/month)
- Cash-on-cash return: 6.4%
Compare this to investing that RM 75,000 in a fixed deposit at 3.5%. The property generates 6.4% on your cash while also building equity through principal repayment and potentially appreciating. Cash-on-cash return captures the leverage effect that gross yield completely misses.
A negative cash-on-cash return means the property is consuming cash. You are effectively paying to hold it. This may be acceptable if you expect significant capital appreciation, but it should be a conscious decision, not a surprise.
Break-Even Rent
The minimum rent at which net cashflow equals zero. If market rent fell to this level, you would neither gain nor lose cash monthly (ignoring capital appreciation).
Use it as a stress test: If the break-even rent is RM 2,100 and current market rent is RM 2,300, you have only RM 200/month of buffer. A 9% rent decline wipes out your cashflow. If break-even rent is RM 1,700 and market rent is RM 2,300, you have a 26% buffer — much more resilient to market downturns.
Worked Example: RM 500,000 Condo in Petaling Jaya
Inputs:
- Property price: RM 500,000
- Monthly rent: RM 2,200 (based on comparables in the area)
- Loan margin: 90% (loan = RM 450,000)
- Interest rate: 4.0%
- Tenure: 35 years
- Maintenance: RM 300/month
- Sinking fund: RM 30/month
- Assessment tax: RM 1,000/year → RM 83/month
- Quit rent: RM 100/year → RM 8/month
- Fire insurance: RM 480/year → RM 40/month
- Repairs allowance: RM 80/month
- Vacancy: 8.3%
- Agent commission: 1 month/2 years
- Residency: Resident
- Other income: RM 72,000/year
Monthly Breakdown:
| Item | Amount (RM) |
|---|---|
| Gross rent | 2,200 |
| Less vacancy (8.3%) | -183 |
| Less agent (4.2%) | -92 |
| Effective rent | 1,925 |
| Less maintenance + sinking | -330 |
| Less assessment tax | -83 |
| Less quit rent | -8 |
| Less insurance | -40 |
| Less repairs | -80 |
| NOI | 1,384 |
| Less mortgage (RM 450K, 4%, 35yr) | -1,991 |
| Pre-tax cashflow | -607 |
| Less income tax (~RM 50/month) | -50 |
| Net monthly cashflow | -657 |
Yield Metrics:
| Metric | Value |
|---|---|
| Gross yield | 5.28% |
| Net yield | 3.32% |
| Cash-on-cash return | -10.5% |
| Break-even rent | RM 2,860 |
This property is cashflow-negative at RM 657/month with 90% financing. The break-even rent is RM 2,860 — roughly 30% above the current RM 2,200 market rent. At 90% leverage, this property does not work as a cashflow investment.
What changes the picture?
| Adjustment | New Cashflow |
|---|---|
| Reduce loan margin to 70% | -RM 57/month |
| Reduce margin to 60% | +RM 221/month |
| Increase rent to RM 2,500 | -RM 399/month |
| All three combined (70%, RM 2,500) | +RM 243/month |
The calculator lets you toggle these variables in seconds. The RM 500K PJ condo works as an investment at 70% financing with RM 2,500 rent — but not at 90% financing with RM 2,200 rent. That is a RM 900/month difference from two variable changes.
What Good Cashflow Looks Like
There is no universal "good" cashflow number. It depends on your investment thesis:
Cashflow investors (want passive income):
- Target: RM 200-500+ positive monthly cashflow per property
- Cash-on-cash return: 4-8%+
- Break-even rent buffer: 15%+ below market rent
- Typically requires lower leverage (60-70%) or above-average rental yields
Appreciation investors (accept negative cashflow for capital gains):
- Target: Negative cashflow within budget (RM -200 to -500/month)
- Focus on capital growth potential, location, and demand drivers
- Treat the monthly negative cashflow as the "cost" of holding the appreciation option
- Must have salary/other income to cover the shortfall
Balanced investors (want both):
- Target: Break-even to slightly positive cashflow
- Cash-on-cash return: 1-4%
- Willing to accept lower current yield for moderate appreciation potential
- Most common profile among Malaysian property investors
The calculator does not tell you which approach is right. It tells you where a specific property falls on the spectrum so you can make an informed decision.
Linking the Four Tools Together
The cashflow calculator is the central tool, but it works best in combination with the other three:
-
Stamp Duty Calculator — Gives you the exact acquisition costs (stamp duty + legal fees). These costs go into your "total cash invested" figure for the cash-on-cash return calculation. They also become allowable expenses for RPGT when you eventually sell.
-
Rental Income Tax Calculator — Deep dive into the tax component. The cashflow calculator estimates tax, but if tax is a significant factor (especially for non-residents), run the dedicated tax calculator for a more detailed breakdown.
-
RPGT Calculator — Models your exit. Before buying, check what RPGT you would owe if you sold in 3, 5, or 10 years at various price appreciation assumptions. A property with break-even cashflow but strong appreciation potential might still be attractive if the after-RPGT gain is significant.

FAQ
What does the net cashflow calculator calculate? Monthly net cashflow, gross yield, net yield, cash-on-cash return, break-even rent. Accounts for vacancy, expenses, tax, and mortgage.
What vacancy rate should I enter? Default 8.3% = one month vacant per year. High-vacancy areas: 16.7%. Tight markets: 0-4%. Materially changes cashflow.
What is cash-on-cash return? Annual net cashflow divided by actual cash invested (down payment + costs). More relevant than net yield for leveraged investors.
Should I enter full mortgage or just interest? The calculator handles mortgage separately. Full principal+interest deducted after NOI automatically.
What is break-even rent? Minimum rent where cashflow = zero. Use to stress-test: if market rent fell to this level, would you still hold?
