WealthCurve
A focused Windows projection app for long-term compound growth scenarios. Compare assumptions, inspect values by age, track milestones, estimate target contributions, and explore Coast FIRE projections.
What WealthCurve does
WealthCurve helps you explore “what if” projections using age, contribution amount, contribution frequency, growth rate, milestones, target planning, inflation assumptions, and Coast FIRE calculations.
Create scenarios
Build saved projection scenarios with starting age, contribution, frequency, growth rate, lump sum, target amount, and more.
Compare outcomes
Compare multiple scenarios on the same graph to see how different assumptions change long-term projections.
Inspect by age
Use age-based graphs and value inspection to understand what each projection may look like at specific ages.
Core features
A focused feature set for long-term projection, scenario comparison, and educational planning.
Age-based graphs
WealthCurve uses age on the graph instead of only “Year 1, Year 2, Year 3,” making projections easier to connect to real life.
Low, base, and high variations
Model uncertainty by showing lower, base, and higher growth assumptions. For example, 11% with ±1% shows 10%, 11%, and 12% paths.
Contribution frequency
Choose weekly, biweekly, semi-monthly, monthly, quarterly, yearly, or custom contribution frequency.
Contribution step-up
Model contributions that increase over time, with an optional maximum contribution amount.
Target Planning
Estimate the contribution needed to reach a target amount by a target age, with gap or surplus summaries.
Coast FIRE Projector
Estimate how much may need to be invested by a chosen coast age to stop contributing and still reach a later target.
Milestones
Track milestone ages for values such as $100k, $250k, $500k, $1M, $2M, and $5M.
Inflation-adjusted values
Optionally include inflation-adjusted values to compare nominal projections with approximate purchasing-power estimates.
Export options
Export projection information as CSV and summary formats for review, record keeping, or personal analysis.
Coast FIRE example
If the target is $2,000,000 at age 65, the coast age is 40, and the assumed growth after coast age is 8%, WealthCurve can estimate the amount needed at age 40.
