Small earnings. A bigger purpose.
Your debit card becomes a vehicle
for your homeownership journey.
Saving for a home can feel like finding room for another expense. Give the cashback from purchases already in your budget a different purpose: add it to your future down payment. You do not need to increase spending or add out-of-pocket contributions to the illustration below.

Linking your card alone does not earn cashback on ordinary debit-card purchases. Saving or investing rewards must be arranged separately. OnestPay does not automatically contribute to a savings or investment account.

Congratulations! With $0 in additional contributions from your pocket, your cashback could help build your future.
You could build $32,237.17 toward your home down payment over 20 yr . At a 20% down payment, that could support an additional $161,185.84 in home purchase price.
This illustration starts at $0 and invests $60.00 in monthly cashback at an assumed 7.5% annual return. Actual returns and rewards can differ.

Extra housing available = additional down payment ÷ 20%. This is an illustration of a larger down-payment budget; it does not establish mortgage eligibility or affordability.
The 7.5% annual return is a hypothetical assumption, not a forecast. Contributions occur at month end. Taxes, fees and inflation are excluded.
Illustrative estimates only. Loan calculations assume a constant rate, monthly interest and payments, and extra cashback applied to principal each month. They exclude fees, penalties and changes in rewards. Savings calculations assume a constant annual return, monthly compounding and end-of-month contributions; they exclude taxes, fees and inflation. Returns can vary and losses are possible. Results are not guarantees.
These are ideas for using your rewards, not automatic OnestPay services. Each illustration applies the full monthly cashback estimate to one goal. Any payments or contributions must be arranged separately. Consider your loan terms and retirement-account rules before making additional payments or contributions.
The bigger picture
Small rewards.
A stronger starting point.
Every cashback contribution adds to the money you can put toward a home. Over time, consistent contributions—and any investment growth—could make that starting point more meaningful.
Your existing savings remain separate. This illustration starts at $0 and shows only what the cashback you enter could add.
Based on your calculator inputs
Your cashback could build $32,237.17 toward a down payment.Putting aside $60.00 each month for 20 yr at an assumed 7.5% annual return could add to your future down-payment budget. At 20% down, that amount could cover $161,185.84 of a home purchase price; affordability and loan eligibility are separate.

A little clarity before you begin.
Does “$0 extra” mean I can buy a home for nothing?
No. It means the additional savings in this illustration are funded entirely by earned cashback. You still pay for your purchases, and buying a home requires sufficient funds, financing where applicable and other costs.
Does the calculator include my existing savings?
No. It starts at $0 and projects only the monthly cashback you enter over your planning period.
Are the return assumptions guaranteed?
No. The return options are hypothetical assumptions. Actual investment returns can be negative. They do not describe a guaranteed savings rate or a return paid by OnestPay.
What does the 20% down-payment illustration mean?
Additional projected down-payment funds divided by 20% equals the portion of a home purchase price those funds could cover at that down-payment ratio. It is a mathematical illustration, not a mortgage approval, affordability estimate or guarantee of a larger home.
Will my debit card earn rewards on every purchase?
No. Cashback applies to eligible purchases paid through OnestPay at eligible stores. Review the current offer and use the OnestPay payment process.
