The Rubiani Capital Builder is a flexible goal-based planning tool designed to help you build capital toward your preferred future objective.
Whether your goal is a holiday, starting a business, building a home, or something completely personal, the principle is the same: build steadily, stay disciplined, and work toward the amount you need over time.
The calculator helps you estimate what your capital could grow to by your chosen year, or what monthly contribution may be required to reach a target amount.
Flexible by Design
Goal-Based Planning
Disciplined Contributions
Compounding Growth
Capital Builder is for anyone who wants to build capital for a future goal in a more structured and disciplined way.
The product is intentionally open, so the destination is your choice while the discipline of building remains the same.
Step 1: Choose your goal Step 2: Set your path Step 3: Track your projection Illustration:
If you invest KES 20,000 per month for 5 years,
your capital could grow to approximately KES 1,562,000 based on the current planning assumptions.
That capital could then be directed toward the goal you have been building for — whether it is a project, purchase, transition, opportunity, or any other objective that matters to you.
This is only an illustration for planning. Use the calculator below to test figures that match your own goal and timeline.
Adjust the goal, contribution, and timeline to see what your capital could grow to, or what you may need to invest monthly to reach your target.
Build toward a specific goal — like travel, home ownership, or business capital — using disciplined investing and compounding.
If you plan to add a one-off top-up at the start, enter it here (optional).
Choose a goal, select a mode, and test different monthly amounts or target values.
The calculator will show whether you’re on track — and what adjustments may be needed.

Projections are illustrations for planning purposes only. Returns are not guaranteed and may vary over time.
Is this product tied to one specific goal? Can I start with my target instead of my monthly amount? Can I include a lump sum? Is the projected return guaranteed? Who is this most suitable for?
Choose your goal, test different contribution levels, and build a practical path toward the future objective that matters to you.
