Baseline beside a hypothetical
A scenario comparison shows how a proposed change affects EastStar's planning metrics relative to the saved baseline. The baseline represents the current profile assumptions. The scenario is a temporary “what if?” version that can change income, expenses, debt, or payments without rewriting that profile.
Examples include testing an extra debt payment, adding a recurring expense, changing take-home income, or considering new borrowing. The comparison can show differences in total debt, monthly obligations, remaining free cash, debt-free date, payoff timeline, and estimated interest cost.
Change one question clearly
A useful scenario begins with a specific question. “What if I add $100 to this debt each month?” is easier to interpret than changing income, three expenses, and two payments at once. When several values change together, the result shows their combined effect but cannot identify which change caused each difference.
Start with current baseline information. Then:
- Name the decision being tested.
- Change only the values needed to represent it.
- Check that the scenario does not count the same money twice.
- Review near-term cash measures and long-term payoff measures.
- Save the conclusion outside the model if it needs follow-up with a lender or professional.
You can create additional scenarios to test uncertainty. For variable income, compare a cautious month with a typical month. For a new cost, compare the expected amount with a higher amount. This gives a range of modeled outcomes rather than one precise forecast.
Reading tradeoffs
Most decisions affect more than one metric. An extra payment can reduce estimated interest and move the debt-free date earlier while lowering remaining free cash. New borrowing can increase total debt and monthly obligations while preserving cash today. A scenario should be evaluated across these tradeoffs, not by whichever number looks most favorable.
Also consider factors outside EastStar: emergency reserves, taxes, insurance, job stability, contractual penalties, and personal priorities. The app cannot assign a universal value to flexibility or risk.
What a comparison can and cannot say
EastStar applies the same simplified monthly model to the baseline and scenario. This consistency makes directional differences useful. It does not make either future certain.
Actual results may differ because balances, rates, expenses, income, and behavior change. Lenders may calculate interest daily, apply payments differently, charge fees, or change a variable rate. A scenario does not reserve money, submit a payment, open an account, or modify the saved profile unless the app explicitly offers and confirms such an action.
Use scenario comparison to narrow questions and expose consequences before committing. After a real decision is made, update the baseline with current information. The new baseline can then support the next comparison without treating an old hypothetical as reality.
Give scenarios clear names or notes when recording their conclusions. “Extra payment” is less useful later than “Add $100 monthly to card beginning in August.” A precise description makes it easier to reproduce the assumptions after balances change. Delete or disregard scenarios that no longer represent a live decision so an outdated comparison is not mistaken for the current plan.
Savings scenarios
EastStar also offers savings scenarios for exploring a target without creating a savings goal. Choose Existing accounts to use the current balances of one or more saved savings accounts, or choose Clean slate to enter a hypothetical starting balance. With either starting point, enter a target amount, APY, and target date. The target amount must be greater than the starting balance.
EastStar estimates the Required monthly savings needed to reach that target by the selected date. It also displays a chart of projected savings by month. The chart applies the entered APY and the calculated monthly savings contribution to the selected starting balance using the same simplified monthly planning approach. It is useful for comparing assumptions, such as a different target date or yield, rather than for predicting an exact bank balance.
For Existing accounts, the scenario reads the balances of the accounts selected when you view it. It does not combine or change their saved planned contributions. For Clean slate, the starting balance belongs only to the hypothetical. In both cases, the scenario's APY and target details are scenario inputs, not changes to the accounts in Profile.
Savings scenarios do not mutate your profile or move money. They do not connect to a financial institution, open an account, schedule a transfer, record a deposit, or change a balance. Use them to test a question, then update Profile or create a savings goal only after you decide what you want to track. Actual interest and balances can differ because rates, transaction timing, fees, withdrawals, and account rules may change.
