Monthly contribution
How it works
P = max(0, (G − S(1+r)ⁿ) / (((1+r)ⁿ − 1)/r))
Using the calculator
Enter: Target amount · Starting amount · Annual rate · Term in months. Calculation: P = max(0, (G − S(1+r)ⁿ) / (((1+r)ⁿ − 1)/r)).
Worked input and result
Example: Target amount = 20,000; Starting amount = 2,000; Annual rate = 5 %; Term in months = 36. Result: Monthly contribution = 456.14.
Understanding the result
Assumes a fixed annual rate compounded monthly and contributions at month-end. Returns zero if the starting balance with interest already reaches the target. Taxes and fees are excluded.
The required monthly contribution assumes a fixed rate and regular end-of-month deposits. Market fluctuations, tax and account fees can affect your real savings plan.
