Here we use the classic formula for Compound Amount:
A = P (1 + r/n)^nt
where P is the intial amount (i. e., the principal), r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.
Then $5994.78 = $4600 (1 + r/12)^(4*12)
or ... $5994.78 = $4600 (1 + r/12)^48
We must solve for r.
Divide both sides of this equation by $4600:
1.303 = (1 + r/12)^48
Take the 48th root of both sides of this equation:
1.0056 = 1 + r/12
0.0056 = r/12 Solve for r: r = 12(0.0056) = 0.0672
The annual interest rate was 6.72%.

The rate of interest monthly is 0.55%.
Given that,
- The deposit amount is $4,600.
- The future value is $5,994.78
- The number of months = 4(12) = 48.
- The payment i.e. PMT = $0
Based on the above information, the calculation is as follows:
The formula is
= RATE(NPER,PMT,-PV,FV,TYPE)
After applying the above formula, the rate of interest monthly is 0.55%.
