How Much Should You Save Each Month? (Simple Guide + USD Examples)
Knowing how much you should save per month depends on your financial goal, your timeline, and whether your savings earn interest. In this guide, you’ll learn simple rules of thumb, practical USD examples, and how to calculate the exact amount using a free online tool.
Use the Savings Goal Calculator to see how much you need to save each month based on your goal, timeline, and interest rate.
1. The Simple Rule: The 50/30/20 Method
A popular budgeting rule suggests saving 20% of your monthly income.
Monthly income: $4,000
Recommended savings: $800/month
This rule works well as a general guideline, but it doesn’t tell you if you'll reach a specific goal in time. That’s where goal-based saving comes in.
2. Goal-Based Saving: Calculate Backwards
To know how much you need to save each month, answer three questions:
- What is your goal? (e.g., $10,000 emergency fund)
- When do you need it? (timeline)
- Will your savings earn interest? (0–5% typical)
3. Clear USD Examples
📌 Example 1: Save $5,000 in 1 year
If you save every month with no interest:
📌 Example 2: Save $10,000 in 3 years
With 3% annual interest (compounded monthly):
Without interest, it would be $278/month — interest saves you time and money.
📌 Example 3: Save $20,000 in 5 years
Assuming a 4% interest rate:
4. How to Calculate Your Exact Monthly Savings
Use this formula (or the online calculator):
Monthly Saving = Goal × r / ((1 + r)n − 1)
- r = monthly interest rate
- n = number of months
Or, simply use the Savings Goal Calculator — it applies this formula automatically.
