How To Increase Your Savings Rate When You Have Multiple Accounts

A savings rate below 20% of net income means you are losing ground — especially with Portuguese inflation at 2.4% in December 2025.

Most advice on growing what you save focuses on cutting spending. That is the wrong starting point. The real problem, for anyone with accounts across two or more banks, is that your actual savings rate is almost certainly lower than you think — because transfers inflate your income figure and distort the number.

Why Your Calculated Rate Is Probably Wrong

You have a salary account at one bank, a savings account at another, and maybe a brokerage account somewhere else. When you export transactions and add up income, that inter-account transfer looks like income twice. Your savings rate appears healthy. It is not.

Portuguese households saved a median of 8.5% of disposable income in 2023 (Pordata). If your number feels comfortable at 12%, strip out the transfers first. It will drop.

The benchmark that matters: 20% of net income, minimum. Below that, retiring before 65 requires either a very late start in index funds or a significant lifestyle adjustment later.

Start with clean data.

What Portuguese Savings Accounts Actually Pay Right Now

Increasing your savings rate is not only about saving more — it is also about not letting what you already save erode quietly. With HICP inflation at 2.4% in Portugal in December 2025 (Eurostat), a savings account paying 1.5% is a guaranteed real loss.

The ECB has cut its deposit rate steadily since mid-2024. In this cycle, Portuguese banks appear to have passed those cuts through faster than they passed through the rises — worth verifying against your own bank’s rate history (Banco de Portugal). ActivoBank, Banco CTT, and a handful of online-only options were still offering between 2.5% and 3.5% on fixed-term deposits as of early 2025 — but check the post-teaser rate before committing; promotional headline rates distort comparisons.

Compare the real rate, not the headline.

High-Yield Accounts and the Transfer Tax You Are Paying

Online banks in Portugal and Spain consistently beat branch-based banks on deposit rates. The reason is structural: lower operating costs. If your main salary account is at a legacy bank paying 0.5% on savings, the gap to an online alternative is often two full percentage points.

Two percentage points on €20,000 in savings is €400 per year, after zero additional effort. That is a reason to separate your operational account from your savings account and place the savings where the rate is better.

The friction is the problem. Most people leave money in low-yield accounts because switching feels complicated.

The Counterargument: Relationship Rates Are Sometimes Real

Some banks offer preferential deposit rates to clients who hold a salary account, mortgage, or investment product with them. Millennium BCP and Caixa Geral de Depósitos have both run these schemes. If a relationship rate at your existing bank exceeds the best standalone rate elsewhere, switching costs real time for zero gain.

In practice, the relationship premium rarely closes the full gap against best-in-market online rates. Take it only if the combined fee savings on other products make the total relationship cheaper than the best online alternative. Also check what you are paying in account maintenance fees.

So What: The Steps That Actually Move the Number

If you want to know your actual savings rate without manually reconciling exports from three different banks, MyCFO calculates it automatically — transfers excluded, so the number is real.

“Two percentage points on €20,000 in savings is €400 per year — for zero additional effort.”

Calculate your true savings rate: sum net income deposits, exclude all inter-account transfers, divide savings by income.
Identify every savings balance earning below the current inflation rate of 2.4% and flag it as a priority to move.
Compare at least three online-only accounts — ActivoBank, Banco CTT, or equivalent. Use the post-teaser rate, not the promotional headline.
Set the transfer to your high-yield account as a standing order on payday, before discretionary spending clears.
Reassess every six months: teaser periods expire, and the best rate today is rarely the best rate next year.

Saving more is partly discipline. Mostly, it is removing friction from the right decision.

The number is 20%

If your savings rate is below 20% of net income and you want to retire before 65, the gap is the problem — not the vehicle you use. Fix the rate first, then optimise where the money sits.

Frequently Asked Questions

How do I calculate my true savings rate when I have accounts at multiple banks?

Add up all net income deposits across every account for a given month. Then subtract all outgoing transfers that represent spending. Exclude any transfer between your own accounts, such as moving money from a salary account to a savings account. Divide the result by total net income and multiply by 100. Most budgeting apps double-count inter-account transfers, which inflates the income figure and flatters your rate.

What is a good savings rate for someone in Portugal or Spain planning to retire before 65?

20% of net income is the minimum benchmark worth targeting if you want to retire before 65 without a dramatic lifestyle adjustment. Below that, you are either extending your working years or relying on portfolio returns to compensate for under-saving. The Portuguese median household savings rate was 8.5% in 2023 (Pordata) — roughly half the threshold that gives you meaningful early-retirement runway.

Should I chase the highest savings account rate or stay with my existing bank for a relationship rate?

Run the numbers on both. Relationship rates at Portuguese banks rarely match the best online-only rates. The difference of two percentage points on a €20,000 balance is €400 per year. Switching a savings balance, unlike switching a mortgage, involves minimal friction. The exception is if the relationship rate also reduces fees on other products. In that case, calculate the total cost of the relationship, not just the savings rate in isolation.

Knowing where to move your savings is only useful if you first know what you are actually saving. MyCFO aggregates balances across all your Portuguese and Spanish accounts and strips out inter-account transfers automatically. The result is one accurate savings rate number.
