Example Data Table
This example shows how weighted contributions combine into a final portfolio result.
| Portfolio Item | Weight % | Return % | Weighted Contribution % |
|---|---|---|---|
| Certifications | 20.00 | 12.00 | 2.40 |
| Portfolio Projects | 25.00 | 18.00 | 4.50 |
| Networking | 15.00 | 9.00 | 1.35 |
| Mentorship | 10.00 | 7.00 | 0.70 |
| Leadership Training | 20.00 | 14.00 | 2.80 |
| Personal Branding | 10.00 | 11.00 | 1.10 |
| Total Gross Return | 100.00 | - | 12.85 |
| Net Return After 0.50% Fee | - | - | 12.35 |
Formula Used
Weighted contribution for each item
Weighted Contribution = (Effective Weight × Item Return) ÷ 100
Gross weighted portfolio return
Gross Return = Sum of all weighted contributions
Net return after fees
Net Return = Gross Return − Annual Fee
Benchmark gap
Benchmark Gap = Net Return − Benchmark Return
Normalized effective weight
Effective Weight = (Input Weight ÷ Total Input Weight) × 100

Frequently Asked Questions
1. What does weighted portfolio return mean?
It is the combined return from all portfolio items after multiplying each item’s return by its portfolio weight. Higher weights create larger influence on the final result.
2. Why might my total weight differ from 100%?
Your entered allocations may be incomplete or intentionally oversized. The normalization option rescales entered weights so the calculator can produce a clean 100% effective allocation.
3. What happens when I enable normalization?
Each input weight is divided by the total entered weight. The result becomes an effective weight that always sums to 100%, which helps compare incomplete plans fairly.
4. Should I include fees in planning scenarios?
Yes. Fees reduce the final return you actually keep. Including them gives a more realistic estimate for long-term planning, evaluation, and goal setting.
5. What does benchmark gap show?
Benchmark gap compares your calculated net return with a chosen reference return. A positive gap means your plan outperforms the benchmark. A negative gap means it trails.
6. Can I use this for career planning scenarios?
Yes. You can model skill investments, projects, training, and certifications as portfolio items. The calculator helps compare how different allocations may affect expected overall value.
7. Why is contribution more useful than return alone?
Contribution shows both importance and performance together. A strong return on a tiny weight may matter less than a moderate return on a large allocation.
8. What do the CSV and PDF downloads include?
They include the calculated portfolio table with weights, returns, and weighted contributions. This makes reporting, sharing, and recordkeeping much easier.
