Easy-access or fixed-term deposits: access versus a fixed rate
How much of my money can I commit for a fixed term?
The first question is not which offer displays the largest percentage today, but when you will need the money. Accessible savings and a fixed term serve different purposes. Compare interest only after clarifying that distinction.
Allocate money according to its purpose
A reserve for unexpected expenses needs to be accessible at short notice. Money needed at a known later date can be planned differently. Easy-access deposits typically have a variable rate; fixed-term deposits commit the agreed amount for the contractual term. Check withdrawal, renewal and interest-payment conditions in the actual contract rather than assuming daily access from a product name.
Two years under three assumptions
A calculation example excluding fees and tax: €10,000 is invested for two years, with interest reinvested at each year-end. A constant 3% produces €10,609. If the flexible alternative earns 3% in year one but only 1% in year two, it produces €10,403. If the second-year rate instead rises to 4%, it produces €10,712. None of these rates is a market forecast.
The cost of flexibility is unknown
The fixed scenario leads by €206 in the first comparison and trails by €103 in the second. Today’s calculation cannot determine the later variable rate. Fixing a rate exchanges an uncertain future development for predictable contractual payments. Remaining flexible preserves access and the opportunity to respond to new terms.
Check protection and access separately
Statutory deposit protection and immediate access are different properties. In Germany, section 8 of the EinSiG generally provides €100,000 per depositor and credit institution; multiple accounts at the same bank do not automatically create separate limits. Check the bank actually holding the account and its protection scheme. This example does not assume a special rule for temporarily high balances.
Staggered maturities can separate the decisions
Instead of committing everything at once, separate amounts can mature on different dates. This creates regular decision points but does not guarantee higher returns. Do not compare interest paid out with interest reinvested without adjusting the assumptions. Your necessary reserve and planned spending should remain affordable under the less favourable rate scenario too.
Easy access answers a liquidity question; a fixed term answers a planning question. Decide when you need access first, then compare payment schedules of equal length with the same treatment of interest.
