Total Income (Total Income): Formula, Examples and How to Get There From Market Rent
Market Rent is what the property could earn. Total Income is what it expects to collect.
The short version: the gap between the two is made almost entirely of leasing, renewal and collections decisions, which means it's made on-site.
Quick Answer Total Income (Total Income) is a property's expected rental income after deductions for vacancy, loss to lease, concessions, bad debt and non-revenue units, plus other income such as fees and parking. The formula is Total Income = Market Rent − Revenue Deductions + Other Income. For example, a property with $2,160,000 of Market Rent, $212,400 of deductions and $108,000 of other income has an Total Income of $2,055,600.
What Is Total Income?
Total Income is the realistic top line of a rental property. It starts from the most a property could earn and subtracts what it won't collect.
Total Income sits at the top of the operating statement, above operating expenses. Subtract operating expenses from Total Income and you get net operating income (NOI).
For the site team, Total Income is the number your leasing, renewal and collections work actually produces. Market Rent describes the building. Total Income describes how well it's run.
Two Definitions You'll See
The term isn't used the same way everywhere, so it's worth knowing both versions.
The appraisal version is short. The California State Board of Equalization defines Total Income as "the anticipated income from all rents after an allowance is made for vacancy and collection losses." Investor guides often fold other income into the starting figure and subtract a single vacancy and credit loss line.
The multifamily operating-statement version breaks the gap into separate lines: loss to lease, vacancy, concessions, bad debt and non-revenue units, then adds other income.
Both land in the same place if the inputs match. This article uses the operating-statement version, because it's how most multifamily operators budget and report, and because each line maps to something the site team controls.
The Total Income Formula
Here's the full waterfall from Market Rent to Total Income:
Market Rent − Loss to lease = Market Rent (Market Rent) − Vacancy loss − Concessions − Bad debt − Non-revenue units = Net Rental Income + Other income = Total Income
Each line is a separate assumption in the budget and a separate line on the operating statement.
Market Rent: The Starting Point
Market Rent is the rent the property would earn if every unit were leased at market rent for the whole period, occupied or not.
Market Rent = Sum of market rents for all units × 12 months
Some statements call this potential gross income (PGI), and some versions of PGI include other income. In this article, Market Rent is rent only.
Market Rent moves when market rents move. If the property raises its asking rents mid-year, Market Rent goes up from that month, even if no lease changes yet. The difference shows up as loss to lease.
The Deductions: Loss to Lease, Vacancy, Concessions, Bad Debt and Non-Revenue Units
Five lines take you from Market Rent to net rental income.
Loss to lease is the gap between market rent and the rent residents actually pay on their current leases. A resident who signed at $1,450 when market rent is now $1,500 creates $50 a month of loss to lease. It's not a loss in the sense of money spent. It's future income the property can capture at renewal.
Vacancy loss is the market rent on units that sit empty. It's the most familiar deduction and the one most tied to the local market. Nationally, the U.S. Census Bureau reported that "National vacancy rates in the second quarter 2026 were 7.3 percent for rental housing." That figure covers all rental housing, not just apartments, so your budget's vacancy assumption should come from your own property and submarket, not a national number.
Concessions are rent given away to sign or keep a lease: a month free, a reduced first month, a gift card. Recording them as their own line, rather than quietly lowering the rent, keeps the true cost visible.
Bad debt is rent that's billed but never collected, usually written off after a resident moves out owing money.
Non-revenue units are units that produce no rent by design: model units, employee units, a unit used as an office, or a unit down for major repairs.
Other Income
Other income is everything besides rent: application and administrative fees, late fees, parking, pet rent, storage, amenity fees and utility reimbursements.
Add it after net rental income to reach Total Income. Fees and utility billing, including RUBS, are regulated at the state and local level, so check your local rules before changing what you charge.
How to Calculate Total Income: A Multifamily Example
Here's an illustrative 120-unit property with an average market rent of $1,500 a month. The numbers are round on purpose.
- Calculate Market Rent. 120 units × $1,500 × 12 = $2,160,000.
- Subtract the deductions. Loss to lease (2% of Market Rent), vacancy (5%), concessions (1%), bad debt (1%) and one model unit total $212,400.
- That's net rental income. $2,160,000 − $212,400 = $1,947,600.
- Add other income. $75 per unit per month = $108,000.
- That's Total Income. $1,947,600 + $108,000 = $2,055,600.
| Line | Annual amount |
|---|---|
| Market Rent | $2,160,000 |
| Loss to lease (2%) | −$43,200 |
| Vacancy loss (5%) | −$108,000 |
| Concessions (1%) | −$21,600 |
| Bad debt (1%) | −$21,600 |
| Non-revenue unit (1 model) | −$18,000 |
| Net rental income | $1,947,600 |
| Other income | $108,000 |
| Total Income | $2,055,600 |
Illustrative example. Not a benchmark for any market.
What the Example Tells You About Occupancy
This property is 95% physically occupied: 5% of the units are empty.
But net rental income is only 90.2% of Market Rent ($1,947,600 ÷ $2,160,000). That's one common way to express economic occupancy, though definitions vary. The other 4.8 points are loss to lease, concessions, bad debt and the model unit.
Two properties can both report 95% occupancy and collect very different amounts of rent. That's why it pays to know the three ways to measure occupancy and which one an owner is asking about.
Total Income vs Market Rent vs NOI
Three numbers, three different questions:
| Metric | What it answers | How it's calculated |
|---|---|---|
| Market Rent | What could the property earn at full occupancy and market rent? | Market rent × all units × 12 |
| Total Income | What does the property expect to collect? | Market Rent − deductions + other income |
| Net operating income | What does the property earn after running costs? | Total Income − operating expenses |
If the example property has $1,031,668 of operating expenses, its NOI is $2,055,600 − $1,031,668 = $1,023,932.
Total Income is also the denominator for the operating expense ratio. Here, that's $1,031,668 ÷ $2,055,600 = 50.2%. Every dollar Total Income misses makes the expense ratio look worse, even if expenses didn't change.
Because value is roughly NOI divided by a cap rate, every dollar of Total Income that reaches NOI is worth many times that in value. We cover how NOI turns into property value in a separate post.
What Moves Total Income On-Site
Each deduction is a result of how the property is run. Here's what each one is worth on the example property:
- Vacancy. One vacant unit-day costs about $49.32 ($1,500 × 12 ÷ 365). One percentage point of vacancy across the year is $21,600. Faster turns and earlier pre-leasing cut it directly.
- Concessions. The $21,600 concessions line equals about 14.4 months of free rent at $1,500. Track concessions by reason (lease-up, renewal, retention) so you know which ones are buying occupancy.
- Loss to lease. If 60 renewals a year are priced $25 a month below where they could be, that's $25 × 12 × 60 = $18,000 a year. Renewal pricing is where loss to lease is won or lost, which is one reason to start working renewals well before expiration.
- Bad debt. At 1% of Market Rent, it's another $21,600. Screening, collections follow-up and payment plans all show up here.
- Other income. An extra $10 per unit per month across 120 units is $14,400 a year. Check local rules on fees and utility billing first.
None of these levers changes the building. All of them change Total Income.
How Total Income Shows Up in the Budget
A strong revenue budget starts from the rent roll, not from Market Rent times last year's collection percentage:
- Which leases expire in each month
- What share you expect to renew, and at what rent
- How many days a turned unit sits empty
- What market rent will be when each unit re-leases
- Which concessions you'll need, and where
Build it that way and every Total Income line has a reason behind it, which is exactly what an owner asks for in a budget review. In Vizibly, revenue is built from the rent roll and lease expirations pulled from the property management system, so those assumptions start from the actual leases rather than a retyped spreadsheet.
Common Total Income Mistakes
- Budgeting from physical occupancy. A 95% occupancy target doesn't mean 95% of Market Rent. Loss to lease, concessions and bad debt still come out.
- Netting concessions into rent. Lowering the recorded rent instead of booking a concession hides the cost and inflates loss to lease.
- Calculating Market Rent at in-place rents. Market Rent uses market rent. Starting from current lease rents makes loss to lease disappear on paper.
- Forgetting non-revenue units. Model and employee units still count in Market Rent, so they need a deduction.
- Treating one-time income as recurring. A one-off settlement or fee spike in other income won't repeat next year.
FAQ
Is Total Income the same as gross income?
No. Gross income usually means potential income before vacancy and collection losses, while Total Income is what's left after those losses, plus other income.
Does Total Income include other income?
In most multifamily operating statements, yes: other income such as fees, parking and utility reimbursements is added after net rental income to reach Total Income.
What is the difference between potential gross income and Total Income?
Potential gross income is what the property would earn fully leased at market rent, and Total Income is what it expects to collect after vacancy, credit losses and other deductions.
Is Total Income before or after operating expenses?
Total Income is before operating expenses; subtracting operating expenses from Total Income gives you net operating income.
What is the Total Income multiplier?
It's a valuation shortcut: sale price divided by Total Income, used to compare properties quickly, not to replace a full valuation.
Is Total Income monthly or annual?
It's usually quoted as an annual figure, but the operating statement shows it monthly, and the months add up to the year.
The Punchline
Market Rent is the ceiling. Total Income is what the team actually brings in.
Loss to lease. Vacancy. Concessions. Bad debt. Other income. Each one is a line on the statement and a decision on-site.
