How the compare savings rates calculator works

It grows the same deposits at two different rates over your horizon and shows the gap between the ending balances — the real cost of leaving money in a low-yield account.

Worked example

Worked example: with amount saved of $25,000, current rate (apy) of 0.50% and higher rate (apy) of 4.50%, the compare savings rates calculator shows extra earned at the higher rate of $12,893.

At 0.50%: $26,282
At 4.50%: $39,175
Difference: $12,893
Extra interest: $12,893

The formula

Each rate compounds (balance + contribution) × (1 + r) per period; the result is the difference between the two ending balances.

Questions about the compare savings rates calculator

How much does a higher savings rate really matter?

Over years, a lot. Moving from a near-zero account to a competitive yield can add thousands on the same deposits, as the comparison shows.

Is switching accounts worth the hassle?

Usually yes — high-yield savings accounts are liquid and FDIC-insured like ordinary ones. The extra earnings shown here are essentially free money.

What is a good savings rate to aim for?

Compare against the best high-yield accounts available; they typically track close to the federal funds rate. Enter both to see your specific gain.

Is the Compare Savings Rates Calculator free to use?

Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
