Vehicle assumptions behind the graph
Illustrative assumptions you can replace. The upgrade is fully financed; its loan is separate from your future payment goal above.
Defer: Virtual Car Lease fund Upgrade now: value minus interest paid Defer: current transport after costs
The red and gold lines provide cost context, not a purchase date. They show car value minus interest or upkeep, not loan equity. The labeled green milestone is when modeled fund growth covers the full future payment.

Compare paying half versus all of the payment

No waitingSplit the payment
The fund pays it
Half the payment from the fund
Full payment from the fund
These waiting periods estimate when growth could cover half or all of the payment without planned use of principal. The car is still paid for: returns vary, selling investments may be needed, and taxes and running costs remain.

Payments from the account
Estimated balance after the term
Contributions stop when waiting ends. Each month, the account earns the assumed return, then pays the selected share of the lease or loan payment. Withdrawals reduce the balance. A finite term can use principal; covering one term does not fund an unlimited series of cars.
What if you keep paying yourself after getting the car?
Stop contributing
Continue the virtual payment
These are alternative paths from the same starting account. Continued deposits are new money from your budget, separate from any share of the car payment you pay yourself. Current-car or public transport costs only reduce deposits during the waiting phase. Future running costs are not modeled.
How the numbers work
During the waiting period: next month's balance = current balance × (1 + annual return ÷ 12) + monthly contribution. Contribution = deferred payment minus current costs, with a minimum of zero.
Growth-covered balance = future monthly payment ÷ (annual return ÷ 12). At zero return, no positive payment can be covered by growth.
During the payment term: next month's balance = current balance × (1 + annual return ÷ 12) minus the selected share of the monthly payment, with a minimum balance of zero. All returns are a constant illustration.
Assumptions and limitations
The opportunity is to turn a payment you delay into an asset you keep. The next car still has a cost; the question is how much of it a dedicated account could help carry.
This simplified model excludes taxes, fees, inflation, volatile returns, changing repair costs, deposits, down payments, insurance, fuel, and lease mileage charges. Depreciation is an assumed constant annual percentage, not a resale quote. The upgrade line subtracts interest, but excludes its maintenance costs; principal payments exchange cash for ownership and are not subtracted again. Future payments remain fixed. This is not a full comparison of vehicle ownership costs. Do not divert money you need for essential transport or repairs.
