Getting started
What does Know Your Money help me do?
It helps you forecast cash balances and explore retirement and brokerage projections. You can see how your entered income, spending, and assumptions affect future results, and identify when the modeled balance may become too low.
Link to this answerWhich calculator should I start with?
Start with Cashflow. Enter your starting balance, regular monthly income and expenses, and upcoming one-time items. Then use that information as a starting point for reviewing your retirement spending assumptions.
Link to this answerIs this a record of what has actually happened?
The forecast is calculated from the data you enter. Scheduled payments and projected balances should not be treated as independently verified bank transactions. Keep your inputs aligned with your actual situation.
Link to this answerHow often should I update my forecast?
Review it when balances, income, bills, or plans change. A regular monthly review can help you catch outdated amounts and missing one-time items.
Link to this answerDoes the app guarantee that my money will last?
No. It shows modeled outcomes based on inputs and assumptions. A forecast with no depletion is limited to its calculation period and is not a guarantee about the future.
Link to this answerCashflow and transactions
Which balance should I enter as my opening balance?
Use the balance at the beginning of the period being modeled, before the transactions included after that point. Using a later balance while also counting payments already reflected in it can double-count those movements.
Link to this answerShould expenses be negative numbers?
Enter positive amounts and choose the correct transaction type. Income adds to the balance and Expense subtracts from it.
Link to this answerWhy can my balance get low when I earn more than I spend each month?
Payment timing matters. Expenses early in a month may arrive before income later in the month. Review the daily balances and monthly low, not just the closing balance.
Link to this answerDoes recurring mean weekly or every two weeks?
Recurring items occur once per active month. Do not use one monthly item as though it automatically represents weekly or biweekly payments. Use separate dated entries where needed to reflect the actual timing.
Link to this answerHow do I enter a bill that increases next year?
Edit its recurring item and use the dated amount-change controls. Enter the new amount and effective month, then save. The app retains earlier dated changes, so you can preserve the history of the bill.
Link to this answerShould I replace the main Amount with the latest amount?
Not if you want to preserve the earlier base amount. The main Amount is used before dated changes take effect. Add a dated change for a later increase instead.
Link to this answerWhat if I save two amounts for the same effective month?
The newer saved amount updates that month’s existing step. It does not create a second payment for the month.
Link to this answerHow do I change just one month’s bill?
Use an override for that individual occurrence. A dated recurring change is for an amount that continues from the selected month onward.
Link to this answerWhat happens to a payment scheduled for the 31st in a shorter month?
The cashflow calculation places it on the last available day of that month.
Link to this answerWhy is my opening balance blue?
In Cashflow, blue identifies an overridden opening balance. It replaces the normal balance carried forward from the previous month. Open the opening-balance editor and use Clear Override if you want normal carry-forward restored.
Link to this answerWhy does a later opening balance stay fixed after I change an earlier payment?
Check for an opening-balance override in that later month. An override establishes a new starting balance there, which can interrupt the effect of changes in earlier periods.
Link to this answerWhat is the difference between going below my threshold and going below zero?
Your threshold is the minimum cash cushion you chose. Going below it means the forecast falls below that cushion. Going below zero means the scheduled movements exceed the cash available in the model.
Link to this answerDoes a daily balance represent the lowest point during the banking day?
No. The cashflow calculation applies the day’s scheduled transactions and records the resulting balance. It does not simulate bank processing times or intraday settlement order.
Link to this answerIncome & Expenses
How is Income & Expenses different from Summary?
Summary focuses on balances: Open, High, Low, and Close. Income & Expenses focuses on transaction totals, separating income and expenses into recurring and one-time categories.
Link to this answerHow do I see what makes up a total?
Open Cashflow → More → Income & Expenses and tap a monthly amount. The detail list shows the transactions contributing to that total.
Link to this answerWhy does a seasonal payment appear under One-Time?
Seasonal recurrence belongs to the app’s one-time item system. Those occurrences remain in the One-Time reporting category even when scheduled in several months or years.
Link to this answerHow do I stop transfers from inflating my income and expenses?
Edit each relevant recurring or one-time item, check Exclude from Income & Expense Summary, and save. The item still affects the cash balance but is omitted from that report’s totals and detail list.
Link to this answerWill naming an item “Transfer” automatically exclude it?
The exclusion checkbox controls reporting. Do not rely on the name alone.
Link to this answerCan I exclude an item I created previously?
Yes. Edit the existing item and change its exclusion setting. You do not need to recreate it.
Link to this answerWhy doesn’t income minus expenses equal the change in my cash balance?
The report can exclude transfers that still move cash. Opening-balance overrides can also affect the balance without being income or expenses. Check those differences before assuming the report is wrong.
Link to this answerRetirement
Is my Social Security start year the same as my retirement year?
It does not have to be. Enter each separately. The retirement calculation applies Social Security only from its configured start year onward.
Link to this answerShould my mortgage amount include property taxes?
No. The clarified mortgage field is for principal and interest excluding property tax. Enter property tax separately, following each field’s displayed units. An escrowed total entered alongside separate property tax can count taxes twice.
Link to this answerWhy do housing costs remain after my mortgage ends?
The model treats property tax separately from the mortgage component. Ending the mortgage does not eliminate property tax.
Link to this answerDo healthcare inputs use today’s costs or future costs?
Use estimated monthly costs in today’s dollars. The app applies its inflation factor. Entering an amount you have already inflated for retirement would inflate it again.
Link to this answerWhat if healthcare is already included in Adjusted Current Costs?
Do not include the same spending in both places. If you use the separate healthcare fields for those costs, remove the corresponding amount from Adjusted Current Costs. The healthcare fields add to the other modeled spending.
Link to this answerWhat do Go-Go, Slow-Go, and No-Go mean?
They are names for optional retirement lifestyle-spending phases. You choose percentages and transition ages to represent your expectations. They are planning assumptions, not predictions about your health or spending.
Link to this answerDoes 90% mean my spending falls by 90%?
No. It means the affected lifestyle component is modeled at 90% of its otherwise-calculated amount—a 10% reduction. It does not reduce every component of your retirement costs.
Link to this answerAre healthcare and housing reduced by the spending phases?
The separate healthcare add-on, mortgage interest, and property tax are not phase-adjusted. The factor applies to the lifestyle/non-housing component. Medical spending left inside Adjusted Current Costs can still be part of that component, so separate your inputs carefully.
Link to this answerWhy didn’t an edited assumption change my withdrawal?
Check whether the withdrawal is manually overridden. A saved manual override takes precedence over the calculated withdrawal for that period.
Link to this answerDoes “funds run out” identify an exact real-world date?
It identifies depletion at the level of detail used by that forecast. Retirement results may identify a year; cashflow can identify a day. Neither establishes when real balances will actually be depleted.
Link to this answerBrokerage & comparisons
Can I add the Retirement and Brokerage results together?
Only if they represent separate funds and you understand the relationship between the models. If both projections represent the same money in alternative scenarios, adding them would count it twice. Automatic transfers or synchronization between calculators should not be assumed.
Link to this answerWhy might another calculator give me a different answer?
Models can differ in starting dates, inflation, taxes, payment timing, return assumptions, withdrawal rules, and the period they calculate. Compare those inputs and definitions before comparing the final balance alone.
Link to this answerWhat-If & Monte Carlo
How do I compare a different retirement year?
Open Retirement What-If, adjust the What-If retirement year, and select Run Comparison. Review the Current Plan and What-If results side by side. See the Retirement Guide for the three distinct planning screens.
Link to this answerWhat does probability of ruin mean?
It is the share of simulated trials in which the balance reaches zero, even if later contributions allow it to recover. It describes the simulation under its assumptions, not a guaranteed real-world probability.
Link to this answerAre the weaker and stronger curves the worst and best outcomes?
No. The displayed 25th, 50th and 75th percentile curves describe the distribution of simulated balances. Outcomes outside those curves are possible.
Link to this answerWhy can Monte Carlo change when I run it again?
Simulated returns vary between trials and runs. Review the trial count and the assumptions shown in the app. A simulation explores a range of outcomes; the standard projection follows its own calculation assumptions.
