CD (Cash Deposit) Balance in Group Health Insurance
A CD (Cash Deposit) balance is an advance float an employer parks with the insurer to run a group health policy. The insurer draws from it to add new joiners mid-term, adjust cover and settle servicing, and refunds it when employees are deleted. For example, adding an employee at a ₹4,000 pro-rata premium deducts ₹4,000 from the CD balance the moment the endorsement is issued.

A CD balance is an advance float the insurer draws premium and mid-term additions from — it earns no interest and must be kept topped up.
How a CD balance works in a group plan
At the start of the policy the employer deposits an advance amount into a cash-deposit account held by the insurer. This balance is not the premium — it is a working float the insurer draws against as the policy runs. Every mid-term endorsement — a new joiner added, a leaver deleted, a dependent updated — is settled instantly against this account instead of raising a fresh invoice each time.
When a new employee joins, their pro-rata premium is deducted from the CD balance and the person is added to cover. When someone exits, the unused portion of their premium is refunded back into the balance. The account is therefore in constant motion, reconciling additions and deletions across the year without HR having to cut a cheque for every change.
The account bears no interest for the employer. If the balance falls below the insurer’s threshold, a low-balance alert prompts HR to top it up; until it is replenished, further additions can be held. At expiry, any credit left over is refunded or adjusted against the renewal premium.
A worked example (CD account ledger)
An employer opens the month with a CD balance of ₹1,50,000. Three employees join at a pro-rata premium of ₹4,000 each, and one employee exits with an unused pro-rata refund of ₹3,000.
Opening balance
3 additions (−₹4,000 each)
1 deletion refund
Closing balance
Every change nets against the same account. If the closing balance had dropped below the insurer’s threshold, the next joiner would wait until HR topped the account back up.
Why the CD balance matters for employers
The CD balance is the quiet piece of plumbing that decides whether a new joiner is actually covered on their first day. If the account is empty, the endorsement stalls — and an employee who believes they are insured can find a cashless claim rejected because they were never added to the live policy.
It also keeps servicing frictionless. Because additions and deletions net against one float, HR is not chasing a fresh invoice for every headcount change. A well-sized balance — tuned to your joining rate — means cover keeps pace with hiring without manual finance steps in between.
The risk is silent depletion. A fast-growing team can burn through a CD account faster than expected, so the low-balance alert is not noise — it is the signal that your next few joiners could otherwise be left uncovered.
How Onsurity handles the CD balance
Onsurity keeps the CD account visible instead of hidden inside the insurer’s back office. HR sees the live balance, every deduction and every refund on the TeamSure dashboard, so there is no guessing whether the account can absorb this week’s joiners.
Additions and deletions are processed digitally, so a new joiner’s pro-rata premium is drawn and their cover goes live without a paper trail. Low-balance alerts reach HR before the threshold is breached, giving time to top up so no endorsement is left waiting.
Pair that with Day-1 cover options and cashless access at 10,000+ network hospitals, and the CD balance does its job invisibly: employees are covered from the day they join, and finance sees exactly where the float stands.
Frequently asked questions
Does a CD balance earn interest?
No. The cash deposit sits with the insurer as an advance float and does not accrue any interest for the employer. It is purely a working balance the insurer draws against to service premium, mid-term additions and claims on the group policy, so it should be sized to cover expected activity, not held as savings.
What happens if the CD balance runs out?
When the balance falls below the insurer’s threshold, servicing pauses: new joiners may not get added and endorsements can be held until you top it up. Insurers send a low-balance alert so HR can replenish it in time. A depleted CD account is the most common reason a genuine mid-term addition fails to reflect before a claim.
Do I get the unused CD balance back?
Yes. At policy expiry any credit left in the CD account is either refunded to the employer or adjusted against the next year’s renewal premium. Deletions of exiting employees also refund their unused pro-rata premium back into the balance during the year, so the account is continuously reconciled.
Is the CD balance the same as the premium?
No. The premium is what the policy costs; the CD balance is the float the insurer draws that premium and mid-term adjustments from. On many corporate plans the annual premium is paid up front and the CD account then handles the pro-rata add/delete activity across the year, keeping servicing instant.
How much CD balance should an employer keep?
Enough to cover a few weeks of expected additions plus a buffer. A fast-hiring team should hold more, because every new joiner’s pro-rata premium is drawn the moment they are endorsed onto the policy. Your broker or the insurer will suggest a threshold based on headcount and joining rate.
