Explain promotional savings rates: compare periods, amounts and subsequent interest

Explain interest as a timeline

When a prospect mentions a promotional rate, your savings sales team first needs a shared timeline. A high percentage does not yet describe the return over the entire planned saving period. What matters is how long it applies, how much money qualifies and what happens afterwards. Breaking this down helps the person choose between a short promotional window and an account intended for longer use. Your offer becomes clearer when you show which conditions belong together and where future developments remain open.

Separate three things in the conversation: the annual interest rate, the actual period during which it applies and the date interest is credited. “Per year” does not turn a four-month promotion into a twelve-month commitment. Crediting interest later does not extend the promotional period either. Ask how the person understood the advertised figure. If they say “I get that rate for a year” although the terms specify a shorter period, you have already identified the main point to clarify.

Establish when the person’s promotion starts

Use the specific terms to establish which event starts the promotion. Opening the account, receiving the first deposit and launching a general campaign are different dates. In preparation, distinguish these possibilities and identify the rule that actually applies. Also ask when the money is likely to be available. If the window starts before the planned transfer, part of the promotion may pass without the intended amount benefiting. Postponing a transfer restarts the clock only if the offer expressly provides for this.

A longer delay can therefore change the decision differently from a small rate difference. Someone awaiting a payment needs a comparison starting with the realistic arrival of their money. Someone who already has the funds faces a different timeline. If the deposit arrives later, keep the remaining promotional window visible. This prevents “four months of promotional interest” becoming an unspoken assumption that every new euro deposited qualifies for four full months. Have the provider confirm the exact period once the opening date is established.

Consider eligibility and amount together

For new-customer promotions, the provider’s definition determines who can participate. “I am new to your advice service” and “I meet the bank’s new-customer terms” are different statements. Check whether the conditions refer to the person, a particular account or a previous period. A past customer relationship should therefore lead neither to automatic exclusion nor automatic eligibility. Where the history is unclear, obtain the provider’s confirmation before using the promotion as the basis for a comparison.

The amount limit matters just as much. If only part of the balance qualifies for a promotional rate, explain both portions. Ask for an approximate planned amount without requesting evidence of wealth for the product comparison. Above the limit, the advertised percentage alone would give an incomplete picture. Separate the qualifying amount from the remainder and identify the rule for each. An additional euro may earn a different rate from the first euros; the largest displayed figure does not imply a uniform rate.

For example, the ING Extra-Konto product information, retrieved on 18 October 2026, distinguishes a first account, a condition concerning previous account ownership, a limited promotional period, an amount cap and a subsequent variable rate. This structure shows why several conditions need to be read together. Use current documentation for your own offer. One institution’s conditions describe neither all easy-access savings accounts nor a particular person’s eligibility at another bank.

Calculate with explicit assumptions

The following calculation is expressly fictional; its rates are not current market offers.

Suppose someone wants to leave €12,000 untouched for twelve months. In the model, offer A pays 3 per cent annually for three months and then a variable rate. For an initial comparison, you assume 1 per cent annually afterwards. Offer B is modelled at 1.8 per cent annually throughout the period. You simplify by using month fractions, a constant balance and a calculation without tax or compound interest. Keep every assumption visible so an illustrative calculation does not appear to promise an exact return.

For offer A, the first three months produce 12,000 times 0.03 times three twelfths: €90. Under the chosen assumption, the following nine months produce another €90. The total is €180. For offer B, 12,000 times 0.018 for the full year produces €216. The higher introductory rate therefore does not automatically win this model comparison. The combination of periods and their rates is decisive. The €216 is also merely the result of the stated assumption, not a forecast for a real account.

Then examine a second continuation for A. At an assumed annual rate of 2 per cent after the promotion, the nine months produce €180; adding the initial €90 gives €270. At 0.5 per cent annually afterwards, the post-promotion interest is €45 and the total €135. This range makes the open assumption visible. It gives no reason to expect a particular subsequent rate. The person can now distinguish the part of the calculation tied to a specified promotional rate from the part depending on a variable continuation.

Include the actual saving pattern

A constant balance is convenient for the model but may be unrealistic for the customer. If they need part of the money for a project after a few months, include that planned withdrawal in a second timeline. Ask about the likely date and the approximate remaining balance. You do not need a private spending list. The practical decision is whether the comparison can assume a full year’s unchanged balance or needs to include an already known change.

With regular deposits, not every instalment earns interest from day one. Assign each planned deposit to its actual period rather than applying the eventual balance retrospectively to the whole year. The same principle works in reverse for withdrawals. A simplified calculation can leave these movements out if you explain the simplification and its significance. Once those movements determine the difference between two offers, use an appropriate calculation method from the product documentation or obtain a professional calculation.

Assess a bundle on its own merits

Some promotions require another product or offer different terms for a bundle. Ask whether that additional product is needed independently of the interest advantage. A current account already planned and an account opened solely for a promotion lead to different decisions. Set out the requirements and any costs alongside the offer using the valid pricing and participation documents. An interest comparison is incomplete if it includes a visible extra benefit but overlooks the further customer relationship needed to obtain it.

Consider the person’s administrative effort too. Will they need to monitor a second account, read additional documents or make another decision after a promotion? Some people find this manageable; others want account administration to be as quiet as possible. Let the person weigh this themselves. A higher modelled return does not yet explain whether the bundle fits their everyday preferences. Your contribution is to present the interest benefit and the additional task clearly side by side, without treating a preference for convenience as financial foolishness.

Treat the subsequent rate as an open decision

If the subsequent rate is variable, do not use it to promise an already determined annual return. Use the currently stated figure as a dated calculation assumption and show how another continuation would change the result. A prospect can then deliberately choose the promotion while understanding that later interest needs another look. That is a different decision from choosing interest fixed for the entire period. Explain the difference before the person relies on a total figure.

A personal reminder for the end of the promotion can help if the person wants to compare again later. Agree what they will review: the actual rate, remaining balance, changed purpose and effort of a possible switch. A reminder does not predetermine a decision. Continued account use might remain attractive, or the saving goal may change. For your sales team, a specific question is more useful than a generic follow-up date: which previously open assumption should now be replaced with the known position?

Finish with a clear comparison

By the end, the person should be able to explain three things in their own words: when their promotion starts and ends, which amount qualifies and what is settled or variable afterwards. Then ask which condition matters most to their decision. If an eligibility requirement remains unclear, clarify that exact point. If the later development is decisive, compare different assumptions. The next step then follows from the interest question rather than a desire to turn every conversation immediately into an application.

When recalculating later, keep the original assumptions identifiable. If only the subsequent rate changes, the saving amount or duration should not also change unnoticed. If the person’s plan changes, say so explicitly. A traceable comparison does not need a complicated table: two clearly described timelines are often enough. What matters is that the person understands why the result differs and what choice follows for them. They can then pursue an offer on a clear and reliable basis.

Compare on the same basis

Also compare offers as of the same date. A promotional page saved last month and a rate retrieved today do not form a fair comparison if eligibility has since changed. Before deciding, check that both offers remain available for the intended start. If a promotion has a fixed application deadline, put that date beside the individual interest start date. The end of the application window and the end of the person’s interest window answer different questions; one deadline does not replace the other.

Check which version you are actually comparing too. An offer for a first individual account may have different requirements from a bundle or an additional account. Label each calculation with the relevant version so an attractive rate does not accidentally sit beside another offer’s conditions. Whenever a requirement changes, recheck the whole related set of terms. This keeps the benefit attached to precisely the product for which it was described.

Finally, the calculated result needs to retain the same meaning. A pre-tax amount cannot be compared directly with an expected personal payout. Use a common calculation basis for the product comparison and label it clearly. If the person’s individual tax position needs to be included, refer that question to the appropriate adviser. This still allows you to compare the interest timeline properly first; it prevents two differently defined results from appearing to represent the same thing.
