What is Savings Goal?
The Savings Goal calculation tells you your monthly saving needed from a few simple inputs. The figure you are solving for here is the monthly saving needed, expressed in INR.
The Savings Goal formula
The core formula is:
Monthly saving needed = Savings goal × (Expected return (p.a.) ÷ 100 ÷ 12) ÷ ((1 + Expected return (p.a.) ÷ 100 ÷ 12)^(Time to Savings goal × 12) - 1)Here is what each input means:
- Savings goal — a money amount. Example: ₹10,00,000.
- Expected return (p.a.) — a percentage, such as an annual rate. Example: 8%.
- Time to goal — a value you set on the slider. Example: 5 years.
How to calculate it step by step
- Write down the savings goal (for example, ₹10,00,000).
- Write down the expected return (p.a.) (for example, 8%).
- Note the time to goal (for example, 5 years).
- Apply the formula above to get your monthly saving needed.
- Double-check the result with the Savings Goal Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Savings goal | ₹10,00,000 |
| Expected return (p.a.) | 8% |
| Time to goal | 5 years |
| Monthly saving needed | ₹13,610 |
| Total you invest | ₹8,16,584 |
| Returns earned | ₹1,83,416 |
With savings goal of ₹10,00,000, expected return (p.a.) of 8% and time to goal of 5 years, the monthly saving needed works out to ₹13,610.
Example 2
With savings goal of ₹20,00,000, expected return (p.a.) of 8% and time to goal of 5 years, the monthly saving needed works out to ₹27,219.

Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
