## What is Compound Interest Simulator?

Simulate your investments and visualize the growth of your savings through the incredible power of compound interest. 

Whether you're an adept of the FIRE (Financial Independence, Retire Early) movement, planing to make a major purchase, or simply looking to understand how your money can grow over time to support a good retirement, this app will be a great asset in your journey for financial freedom.

This calculator is ideal for simulating fixed income investments, planning your savings, visualizing wealth evolution, and achieving retirement goals or financial independence plans.

Getting started with the "Basic Mode" is easy: Just input the initial amount of money (if any), an optional monthly deposit, the interest rate and how much time you are planing to keep your capital invested. This app will then show you all the information you need in a beautiful graph, accompanied by a detailed analysis for the selected period.

For more customization, the 'Advanced Mode' offers additional features: You can add multiple deposits and withdrawals over time, choose different compounding frequencies (such as daily or quarterly), and adjust the number of days in a year. For example, you can simulate a scenario where you make significant monthly deposits for 30 years, and then begin making annual withdrawals of a percentage of the balance. This calculator is that flexible.

Watch your money work for you, and achieve your financial goals with the magic of compound interest!

Note: This app is for informational purposes only, may contain inconsistencies, and in no way replaces personalized financial advice from a qualified advisor. Investment decisions and life-saving strategies should be based on professional guidance and not on information from unknown sources on the internet.

### 5/5 — Michael

*2026-08-04*

Great app

### 5/5 — Très performante

*2026-07-26*

Cette application répond exactement à mes besoins. Après en avoir essayé plusieurs qui ne me convenaient pas. Je l’ai adoptée.

### 5/5 — A melhor e mais completa

*2026-07-06*

Recomendo, me ajuda demais no cálculo das previsões de rendimentos.

### 1/5 — Einziger Zinsrechner mit monatlicher, wöchentlicher Zinszahlung. Aber schlimme Datenkrake!!

*2026-07-02*

Bitte Berechnung mit sich ändernden Zinssätzen ermöglichen! Zb erst 4 Monate 4% Aktionszins, dann 2% Standard Zinsen. Dann Zinssatz-Erhöhung auf zb 3% für konkrete Zeiträume. Unabhängig davon zu stark an meinen Benutzerdaten interessiert!!! Das fängt hiermit an: „210 Partner werden Ihre personenbezogenen Daten verarbeiten und dürfen Informationen von Ihrem Gerät (Cookies, eindeutige Kennungen und andere Gerätedaten) speichern und darauf zugreifen. Die Informationen von Ihrem Gerät können mit den Partnern geteilt oder speziell von dieser App verwendet werden. Wir und unsere Partner dürfen genaue Daten zur Standortbestimmung verwenden.“
Danach kommen noch über 50 Firmen mit angeblich berechtigtem Interesse an der Erhebung MEINER Daten! Fällt euch was auf?

### 1/5 — disappointing.

*2026-06-29*

initially I entered 84.25 % p.a. as interest rate. I changed to 5.25% but calculations would not alter

### 5/5 — IDEIA DE MELHORIA

*2026-05-25*

App muito bom. Recomendo muito. Eu gostaria que tivesse a função de considerar o aumento do investimento ao longo do tempo. Pois para empreendedores, o depósito mensal em investimentos, tende a crescer ao longo do tempo também.

### 5/5 — Muito bom

*2026-02-12*

Poderia ter um botão de “+ “ e de “-“ para facilitar limitar o tempo de limite de depósitos e retiradas

### 5/5 — Fantástico!

*2026-02-04*

Excelente app, útil, prático e com uma ótima interface!

### 5/5 — Mega gut 👍

*2026-01-31*

Ich war auf der Suche nach einer App, welche mir die Zinsen und Zinseszinsen ausrechnen kann.

Bei dieser App bin ich hängen geblieben, da diese die Berechnungen für mich nachvollziehbar aufschlüsselt. Und dies macht sie um Welten besser als andere Apps die ich getestet habe.

### 5/5 — Exactly what I was looking for.

*2026-01-08*

Exactly what I was looking for. Thanks!
