Tiered Savings / FD Effective Rate Calculator (Malaysia)

Find the true blended interest rate for tiered savings or fixed deposit accounts. Supports step-style tiers and slab-style tiers, and compares against a simple flat-rate FD.

How tiered savings and FD interest really works in Malaysia

Many Malaysian savings and fixed deposit accounts advertise tiered interest structures such as "First RM20,000 at 3 percent, next RM30,000 at 4 percent, above RM50,000 at 1.5 percent". The headline sounds attractive, but the actual blended rate you receive depends on your balance and how the tiers are applied.

Step tier vs slab tier interest

In a step or marginal tier structure, each ring of your balance earns the rate of that tier. For example, if you have RM60,000, the first RM20,000 may earn 3 percent, the next RM30,000 earns 4 percent, and only the remaining RM10,000 earns 1.5 percent. Your overall effective rate is the weighted average of these portions.

In a slab structure, once your balance crosses a tier threshold, the entire balance earns that tier rate. Using the same RM60,000 example, if it falls into the highest tier, all RM60,000 might earn 1.5 percent. This can be very different from a step structure, which is why it is important to know which model your account uses.

When a tiered savings account can be worse than a simple FD

  • Your balance sits mostly in low tiers with modest rates.
  • The highest advertised rate only applies to a small portion of your money.
  • Bonus rates require conditions like monthly deposits or card spend that you do not meet.
  • A simple FD at a flat rate could give more interest with less effort.

The Tiered Savings / FD Effective Rate Calculator helps you see the full picture by breaking down interest from each tier and comparing it with a plain FD rate of your choice. Instead of guessing based on marketing banners, you can check the true effective rate based on your own balance and holding period.

Limitations of this calculator

  • Uses simple interest for the chosen number of months and does not model daily compounding.
  • Does not check complex eligibility rules for bonus interest or promotional campaigns.
  • Does not factor in tax, account fees or other conditions.
  • Does not represent any specific bank, product or recommendation.

Treat the output as an educational estimate. If the tiered product only beats a normal FD by a small margin, the extra complexity and requirements may not be worthwhile. Always read the product disclosure sheet and speak to your bank if you are unsure how interest is calculated.
