Savings growth with monthly contributions

Amounts in MAD. Interest is added monthly and contributions are made at the end of each month.

Starting amount (MAD)Monthly contribution (MAD)Annual return (%)Duration (years)

Total you put in: 170.000,00 MAD
Interest earned: 51.791,44 MAD
Final balance: 221.791,44 MAD

Interest is added every month and contributions are made at the end of each month. A fixed rate is an assumption, not a promise of return.

How it works

With compound interest, the interest you earn is added to the balance and then earns interest itself.

The balance after n months is P × (1 + r)^n + C × ((1 + r)^n − 1) ÷ r, where P is the starting amount, C the monthly contribution and r the monthly rate (annual rate ÷ 12).

Starting with 50 000 MAD, adding 1 000 MAD a month at 4% a year for 10 years, you put in 170 000 MAD and the balance is about 221 791 MAD.

Read it carefully

The rate is an assumption you choose. Real returns change and are not guaranteed.
The result ignores inflation, fees and tax on the interest.
It is a general calculation, not advice on where to save or invest.

Questions

Is the return guaranteed?

No. The tool applies the rate you type, nothing more. Real products have their own rates, fees and risks.

When are contributions counted?

At the end of each month, so a contribution earns interest from the following month.

Does it account for inflation or tax?

No. Both reduce what your savings are worth in practice. Ask your accountant about tax on interest.
