How it’s Calculated
Connecticut General Statutes § 47a-21 mandates landlords pay interest on security deposits held for more than one year. The interest rate is set annually by the state. The formula used here is: Total Interest = Deposit Amount * (Annual Interest Rate / 365) * Number of Days. Note: Interest typically only accrues after the deposit has been held for at least one full year.

What is the Connecticut Security Deposit Interest?
The Connecticut Security Deposit Interest refers to the mandatory interest that landlords must pay to tenants on security deposits held for more than one year. This regulation is designed to compensate tenants for the use of their funds by the landlord and to ensure that landlords do not profit unfairly from holding tenant deposits. In Connecticut, landlords are legally obligated to pay this interest, with the rate determined annually by the state. This practice protects tenants and promotes fair rental agreements. Understanding this requirement is crucial for both landlords, who must comply with the law, and tenants, who are entitled to this earned interest.
Who Should Use This Calculator?
- Connecticut Tenants: To verify the amount of interest they are owed on their security deposit if it has been held for over a year.
- Connecticut Landlords: To accurately calculate and pay the legally required interest to tenants, ensuring compliance and avoiding disputes.
- Property Managers: To manage security deposit interest calculations efficiently and maintain accurate financial records for rental properties in Connecticut.
Common Misconceptions
- “Interest is paid immediately”: Interest is generally only paid if the deposit is held for a full year or more.
- “Landlord sets the rate”: The interest rate is set by state statute annually, not by the landlord.
- “Interest is paid annually automatically”: While some landlords may pay it annually, the law specifies when it becomes due, and tenants can claim it. It’s not always automatic without tenant request.
- “Interest applies to damages”: The calculated interest is separate from any potential deductions for damages or unpaid rent. It’s calculated on the full deposit amount held.
Connecticut Security Deposit Interest Formula and Mathematical Explanation
The Core Formula
The calculation for the interest owed on a security deposit in Connecticut is straightforward, based on the deposit amount, the applicable annual interest rate, and the duration the deposit was held. The primary formula is:
Total Interest = Deposit Amount × (Annual Interest Rate / 365) × Number of Days Held
Step-by-Step Derivation
- Determine the Number of Days: Calculate the exact number of days between the date the security deposit was received and the date for which you are calculating the interest. This is the duration the landlord has held the funds.
- Find the Applicable Annual Interest Rate: Identify the official annual interest rate set by Connecticut statute for the relevant period. This rate is usually updated yearly. For simplicity and current use, we use the rate applicable for the period closest to the calculation date, or the current year’s rate if the period spans multiple years.
- Calculate the Daily Interest Rate: Divide the Annual Interest Rate by 365 (or 366 in a leap year) to find the daily interest rate.
- Calculate Total Interest Accrued: Multiply the Security Deposit Amount by the Daily Interest Rate, and then by the Number of Days the deposit was held.
Variable Explanations
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Deposit Amount | The total sum of money collected as a security deposit. | USD ($) | $50 – $5,000+ (Often capped at 2 months’ rent) |
| Deposit Received Date | The specific date the landlord received the security deposit from the tenant. | Date | YYYY-MM-DD |
| Interest Calculation Date | The end date up to which interest is being calculated. | Date | YYYY-MM-DD |
| Number of Days Held | The total number of days between the Deposit Received Date and the Interest Calculation Date. | Days | 0 – Many Years |
| Annual Interest Rate | The official interest rate set by Connecticut law applicable to security deposits. | Percentage (%) | 0.06% – 3.00% (Varies by year) |
| Daily Interest Rate | The Annual Interest Rate divided by 365. | Percentage (%) | ~0.0002% – 0.0082% |
| Total Interest Accrued | The total interest earned on the security deposit. | USD ($) | $0 – Varies widely |
Practical Examples (Real-World Use Cases)
Example 1: Standard Calculation
Scenario: A tenant paid a $1,600 security deposit on January 15, 2022. They are moving out on March 1, 2024. The landlord needs to calculate the interest due.
Inputs:
- Security Deposit Amount: $1,600
- Deposit Received Date: 2022-01-15
- Interest Calculation Date: 2024-03-01
Calculation Steps:
- Number of Days: From 2022-01-15 to 2024-03-01 is 776 days.
- Annual Interest Rate: For deposits held over a year, the rate applicable in the year the interest is *due* or calculated often applies. Let’s assume the 2023 rate of 1.50% is used as a recent standard for calculation purposes if held beyond 2023. (Note: The exact rate depends on the specific holding period and CT statutes).
- Daily Interest Rate: 1.50% / 365 = 0.0041096% per day.
- Total Interest Accrued: $1,600 × (0.0150 / 365) × 776 = $53.57 (approximately)
Result Interpretation: The landlord owes the tenant approximately $53.57 in interest, in addition to the return of the $1,600 security deposit (less any legally permissible deductions).
Example 2: Recent Low Rate Scenario
Scenario: A tenant paid a $1,200 security deposit on June 1, 2020. They are calculating the interest due as of June 1, 2021 (exactly one year later).
Inputs:
- Security Deposit Amount: $1,200
- Deposit Received Date: 2020-06-01
- Interest Calculation Date: 2021-06-01
Calculation Steps:
- Number of Days: From 2020-06-01 to 2021-06-01 is 365 days (2020 was a leap year, but the period doesn’t include Feb 29th within the calculation span itself, and 2021 is not).
- Annual Interest Rate: The rate for 2021 was 0.06%.
- Daily Interest Rate: 0.06% / 365 = 0.0001644% per day.
- Total Interest Accrued: $1,200 × (0.0006 / 365) × 365 = $0.72 (approximately)
Result Interpretation: Even though the deposit was held for a full year, the very low interest rate set by the state resulted in only $0.72 of interest being owed. This highlights how the official rate significantly impacts the amount of interest.

Key Factors That Affect Connecticut Security Deposit Interest Results
Several elements influence the final interest amount calculated for a Connecticut security deposit. Understanding these factors is vital for accurate calculations and fair practices:
- Deposit Amount: This is the principal base for interest calculation. A higher security deposit directly results in more interest earned, assuming all other factors remain constant. Landlords in CT can typically require up to one month’s rent as a security deposit, though this can sometimes be more depending on lease terms and local ordinances.
- Duration the Deposit is Held (Number of Days): Interest accrues over time. The longer a landlord holds a security deposit, the more interest accumulates. Connecticut law specifies that interest generally becomes payable if the deposit is held for more than one year. The precise number of days between the receipt date and calculation/return date is critical.
- Official Annual Interest Rate: This is perhaps the most volatile factor. Connecticut law mandates an annual rate, which can fluctuate significantly based on economic conditions. Rates have ranged from very low (e.g., 0.06%) to higher figures (e.g., 3.00%). This rate is not set by the landlord but by state statute, ensuring fairness and consistency.
- Leap Years: While most calculations use 365 days in a year, leap years (containing 366 days) can slightly alter the daily interest rate calculation if the holding period includes February 29th. This affects the precision of the calculation over longer durations.
- Timing of Calculation/Return: The exact date chosen for calculating interest impacts the total number of days. For landlords, timely return of the deposit with accrued interest (less deductions) is crucial. For tenants, knowing when interest starts accruing (after one year) helps them track their entitlement.
- Statutory Compliance and Legal Nuances: Connecticut General Statutes § 47a-21 governs security deposits. Specific clauses regarding notification, how interest is paid (annually or at move-out), and allowable deductions can affect the net amount received by the tenant. While the calculator computes gross interest, landlords must adhere to all legal requirements for deductions and timely payments.
- Inflation and Real Return: Although not directly part of the calculation formula, inflation impacts the *real* value of the interest earned. A high interest rate might seem good, but if inflation is higher, the purchasing power of the interest earned might be diminished. The state sets the rate partly to reflect broader economic conditions.
- Potential Fees or Taxes: While interest earned on security deposits is generally considered taxable income for the tenant in the US, specific tax implications should be consulted with a tax professional. Landlords might also incur costs related to managing deposits, though these aren’t typically deducted from the tenant’s interest.
Frequently Asked Questions (FAQ)
Yes, under Connecticut General Statutes § 47a-21, landlords are required to pay tenants interest on security deposits if the deposit is held for more than one year. The interest rate is determined annually by the state.
The interest rate is updated annually. For the most current year, you can check the Connecticut Department of Consumer Protection or financial news sources. The rate for recent years has varied, for example, 1.50% in 2022-2023, and 0.06% in 2020-2021. Always verify the rate applicable to the period your deposit was held.
You are entitled to receive interest if your security deposit has been held for more than one year. The law specifies how and when this interest should be paid, typically either annually or upon termination of the tenancy.
The number of days is calculated from the date the landlord received the security deposit until the date the interest is being calculated or the tenancy ends. Our calculator handles this date difference automatically.
Landlords can deduct amounts from the security deposit for damages beyond normal wear and tear or for unpaid rent. However, the interest earned is generally considered the tenant’s money. Deductions typically apply to the principal deposit amount, not the accrued interest itself, unless specific lease terms or legal interpretations allow otherwise. Always review your lease and CT statutes.
If a landlord fails to pay the legally required interest, tenants may have grounds to take legal action. This could involve filing a small claims court case or contacting the Connecticut Department of Consumer Protection for assistance. Keeping records of your deposit payment and lease agreement is crucial.
