What is a dividend portfolio calculator?

A dividend portfolio calculator aggregates multiple dividend-paying stocks into a single view showing total forward annual income, blended yield, value allocation, and income distribution. Rather than calculating each position individually, it gives you a portfolio-level picture of income, yield, concentration, projected growth, and dividend quality across all holdings at once.

How is blended dividend yield calculated for a portfolio?

Blended portfolio yield = Total Forward Annual Income / Total Portfolio Value × 100. It weights each holding's yield by its value contribution — a large holding with a low yield dilutes the portfolio yield more than a small holding. The Portfolio Builder calculates this automatically from all entered holdings.

What is dividend portfolio concentration risk?

Concentration risk means too much of your dividend income depends on too few holdings. If one stock contributes 40% of total income and cuts its dividend, your portfolio income falls by 40% immediately. The Income Analysis tab calculates the Herfindahl-Hirschman Index (HHI) — an industry-standard concentration measure — and flags any holding whose income share exceeds a threshold you set in the Rebalancer.

How does the dividend quality score work?

The quality scorecard rates each stock 0–100 across five weighted metrics: forward yield (20 points), EPS-based dividend coverage ratio (25 points), 5-year dividend growth rate (25 points), consecutive years of dividend payments (15 points), and payout ratio (15 points). Each metric is scored on a rubric — for example, a coverage ratio above 3× earns 25 points while below 1× earns 0. Scores of 80+ are Excellent, 60–79 are Good, 40–59 are Moderate, and below 40 are Weak.

What each tab calculates

Portfolio Builder

Enter all holdings with shares, price, annual dividend, sector and frequency. Auto-calculates yield, income, value weight and income weight per row. Dual doughnut charts for income and value allocation plus three KPI summary cards.

Income Analysis

Breaks income down by sector and frequency with visual bars. Builds a 12-month income calendar. Calculates Herfindahl index concentration score and flags over-concentrated positions by income share.

Growth Projector

Projects total portfolio income using blended DGR, price growth and optional monthly contributions. Shows multiplier, projected value, total dividends earned, yield on cost, and a dual-axis line chart.

Rebalancer

Compares current blended yield against a target or equal-weight goal. Flags over-concentrated positions and generates specific buy/reduce/hold recommendations per holding.

Quality Score

Scores each stock 0–100 across yield (20 pts), coverage (25 pts), DGR (25 pts), streak (15 pts) and payout (15 pts). Grades from Excellent to Weak with a portfolio average and ranked bar chart.
